Background of the Invention The present invention relates to interactive hand- held devices, and more particularly to methods and apparatuses for receiving and decoding modulatea signals, for use by a hand-held devices and receiving benefits from receptions of the signals. The hand-held device of the present invention receive modulated video signals for purposes including en oyment, promotion, transfer of information, data collection, commercial verification, security, education, and transactions or verifications at points of sale, as well as other commercial, personal, entertainment, or amusement purposes. Data may be sent to tne hanα-held αevice by optical or electrical means. Data may oe received by tne hand-held device by utilizing a sleeve, cradle, or docking station; through an optical lens, by use of a PCMCIA or alternate computer port, or by FM, AM, or other radio frequency means. Use of tne device may allow users to receive, process, and/or store other information ana promotional opportunities including access to hote_ rooms and facilities ana interaction m a movie theater. U.S. Patent 4,807,031 Broughton et a... ("Broughton" ) titled "Interactive Video Method and Apparatus" relates generally to m-band video broadcasting of commands and other encoded information to interactive αevices. The invention described therein relates generally to interactive eαucational and entertainment systems, and is described in one embodiment m the context of television program contrc ^ of toys located where there is a television receiver, as within a resiαence. To encoαe control data capable of providing a oenefit to a user, Broughton discloses a novel method of luminance or chrominance modulation of a video signal that creates a composite video signal, wnereby the control data is created by modulating the video signal. The novel modulation method alternately raises and lowers the luminance/ chrominance of adjacent norizontal scan lines to create a video subcamer tnat contains the control data. Under Broughton, the video signal is not being replaced with other data, nor is the data being added as a separate signal along with the video signal, rather, the video signal itself is modulated to subsequently create the control data. Therefore, tne control data is a part of, or contained within, tne video signal. The encoding method also includes preview and remove circuitry to ensure suitability or the presence of data encoding and removal of data encoding, respectively. The control data is trans itteα either by television broadcast means, or by pre-recorded video players that are connected to a video display. The control data is then received by the video display where a video field of the video display is modulatea by control (i.e. auxiliary) data. The control αata is then detected with either opto-electronic or RF radio frequency) detection means that discriminate tne program material from the control data. The detected control data is further reproduced such that the control data can be used witn an interactive device. A practical example of a device as described above is the commercially-sold hand-held game device for receiving and detecting such control data has been called the "Wheel of Fortune" ITV Play-Along Game, intended to be used at while viewing a television program presentation of the famous television show of the same name. The device, produced unoer license by the assignee of Broughton, was a palm-sizeα device and included a photosensor within a case of tre device that received the video signals. The device e" discriminated control data from the video program material and caused a liquid crystal display ("LCD'"* on the face panel of the toy to present portions of a word puzzle, allowing the holder of the device to play the game along with a contestant or to play in response to a videotaped presentation of the game. The "Wheel of Fortune" interactive television (ITV game together with its rand-held control device including keyboard was commercially available in 1988. An improvement on the metnod of modulation described in Broughton is described m U.S. Patent 6,094,228. In Ciardullo et al. ("Ciardullo" improved methods of modulation are disclosed. Data is inserted on the visual portion of a video signal by cnangmg the luminance of paired lines in opposite directions, thus allowing allow larger amounts of data to be modulated m a signal. Brougnton and Ciardullo are both incorporated by reference herein. Efforts by others to provide hand-held devices capable of receiving transmission of modulated data from a video display are represented by U.S. Patents 5,594,493; 5,761,601; 5,767,896, 5,907,350, and 5,953,047. Of these, patent 5,90 ^ ,350 discloses a method for storing data on a so-called smart card, which is contended to receive, decode and store encoded data signals comprising redeemable coupons said to be embedded within television segments ana transmitted along with normal television segments. Tne device of Patent 5,907,350 is a nand-held unit that receives luminance signals from the television display in accordance with the principles of Broughton. The received video signals are decoded and stored within the card for future use. An LCD readout enables Universal Price Codes ("UPC") corresponding to the stored data. A scanner reads the UPC codes at a redemption site, and the stored coupon is then erased from a memory of the card. A microprocessor cnannels the decoding and storage aspects, and a keypad allows use and input. The term "smart card" as used m the above patents, connotes a hand-held, portable device, not conceptually different from the above-mentioned "Wheel of Fortune" ITV game device. However, the term ooes not only apply to those patents. As a generic term, "smart card" gradually has come to mean a card that looks like a credit card but includes a microchip or microprocessor emoedded or incorporated into the card. The smart card may be referred to as a "fmgerheld" computer, typically including a data storage media ranging from less than a kilobyte up to a megabyte (if not more), and are said to have originated m France. Ognibene, P.J., "Card Smarts," Technology Decisions (July, 1999) . Smart cards may, according to a line of reference, also be called "chip cards." While the hand-neld devices of the present invention may be m tne form of a smart card, they may alternatively be in the form of mobile phones. Recently, mobile phones have become equipped with increased capacity to store and process information and many sucn phones are now offering limited network or Internet access, often called wireless Internet access. Industry experts estimate that by 2002, more than 100 million mobile phones will nave Internet access in some fashion and that by 2003, more than 1 billion mobile phones w ll be in use worldwide. Such mobile pnones, with or without Internet access, oecome powerful promotional too_.s when appropriately modified or connected to receive auxiliary data . The personal digital assistants ("PDAs") are another hand-held device capable of providing users with promotional opportunities. The most popular brand, Palm Pilot, introduced its first PDA in 1996. The latest Palm Pilot introduced m 1999, Palm VII, was the first PDA to include wireless Internet access. PDAs and mobile phones, while capable of Internet access, as of the time of this invention nave limited functionality as a result of slow transfers of data and limited displays. It is thus desiraole to provide users of such devices and similar devices such as smart cards interactive opportunities that are compact in size yet rich m content to encourage users to participate m various promotional opportunities without naving prolonged delays m receipt and processing of information. It will be appreciated that under the present invention, that the smart card, mobile pnone, and PDA are all capable of providing the promotional opportunities described m the present application. Hanα-held devices that receive optically encoded data from a display device can be efficiently utilized at a POS without the need to scan a UPC cooe that is displayed, for example, on an LCD. The hand-neld devices and methods may not require additional narαware or software at tne POS and must be capable of providing a high degree of security. Additionally, cneck-out time must not be seriously degraded and multiple promotional opportunities or coupons must be redeemable. For purposes of the present invention, the term "card" means an interactive device of portable character, preferably of hand-held type which may oe carried in the palm by a user, between fingers of the user, or is otherwise intended to be easily grasped and handled manually by the user, including credit card-like devices. To the extent that they are used in tne present description relative only to inventions herein disclosed and/or claimed, the terms "interactive device," "card," "interactive card," "smart card," "optical card," are used interchangeably. The term "sponsor" is used herein in its broadest possible sense, and may include without limitation entities that issue the hand-held devices and entities that accept them or provide redemption services for users of the cards. Sponsors may also include health care and medical institutions and otner service or eleemosynary organizations. The term "computer" is used herein m its broadest possible sense, and may include without limitation a laptop computer, personal computer, mobile phone, personal digital assistant, or other computer like devices. Summary of the Invention Among the several objects, features and advantages of the invention may be noted the provision of interactive hand-held devices for carrying out various modes of novel and commercially advantageous signaling, information-transferring, and value-inαicating methods. The hand-held devices of the present invention are portable devices such as smart cards, mobile phones, and personal digital assistants ("PDAs"/, which contain means to receive auxiliary data. The nand-held devices, to provide some of the promotional opportunities described herein, preferably have means to connect to the Internet, which may be referred to herein as "network access", "wireless access", "Internet access" or "wireless Internet". These hand-held devices react from the reception of auxiliary data from sources including radio transmissions, computer systems, video recordings, video transmissions or other sources for reproduction of vioeo, audio and/or other data. Tne nand-held devices, whicn preferably contain optical or electrical detection and decoding means, respond to auxiliary data received from a video display. All video displays, whether a television set or monitor, television-like, or image- presenting display device capable of displaying an image containing a modulated video signal, may in the present specification be collectively referred to simply as "display devices." Signals are received, detected, and reproduced by the new nand-held devices for various purposes including: enjoyment; promotion; coupon or prize validation; advertising by sponsors; advertising verification and polling; transfer of information; data collection; commercial verification; security and access; education; game playing; transactions, verifications, or redemption by sponsoring entities or related commercial locations at points of sale including tne Internet; other commercial and non-commercial purposes. Transmission of auxiliary data to the hand-held devices is encoded using a system of video modulation, preferably as described in Broughton or Ciardullo, but alternatively by other known metnods in the art including through the use of the vertical-blanking interval (VBI). The video signals may be transmitted to the display device by means of a broadcast, cable, satellite or home video . Other objects, features and advantages of the invention include: A method of television interactive advertisement and promotion signal transmission using interactive hand-held devices m such a manner that both the mode of transmission of information and the display of received information and/or value indicative thereof will attract viewers' attention, stimulate viewers to watch a transmission (whicn may be commercial advertising) , and effectively entice viewers to respond and take action m response to its reception, as well as achieving the foregoing usage purposes. Thus, there is described herein a system wnich includes : A method of sucn signal transmission that is cost effective, brand efficient, and fun for users of the new interactive hand-held devices; A method of such signal transmission using interactive hand-neld devices whicn effectively increases customer awareness, retention, and differentiation of advertisers' messages and products; A method of sucr signal transmission using video interactive hand-nelα devices which allows viewers of television (or video presentations, including advertising, to directly interact with the devices (such as television receiver or display) ; A method of sucn signal transmission using interactive hand-neld devices that builds store (point- of-sale traffic, fosters consumer loyalty, ana gives viewers a reason to pay more attention to a company' s products, services and advertising; A method of such signal transmission using video interactive hand-neld devices which allows viewers of television (or video 1 presentations, including advertising, to upload received information to a computer which displays ana uses relevant Internet addresses, textual information or code, and other promotional information usable by a computer or computer-like device; and Hand-held devices of the invention are intrinsically simple, effective and economical to make and distribute widely, and are reliable and easy to use. The following are merely illustrative of some of the advantages and objects which the new system provides: television advertising response determination; interactive advertising and promotions; attraction of viewers' attention; effectively increase consumer awareness and retention cf commercial advertising, messages, announcements, promotions, and specific products and services; increased customer differentiation of products and services; stimulation of viewers to watch commercials; increase of store traffic in response to commercial messages; fostering of consumer loyalty; enhancement of viewer involvement m program content, including commercials; enhancement of viewer retention of the content of commercial and other messages; enhancement of the value of commercial messages; increased product /service sales; saving of advertising costs; acceleration of response time of customers following delivery of commercial messages; verification of contests and awards; enhancement of viewer retention of the related website domain names; reduction of Darners related to e-commerce opportunities; additional and sometimes instant rewards and information obtainable via tne Internet. The uses and advantages are more fully developed in the following description. Briefly, herein described is a system using handheld devices that derives benefits from the reception of auxiliary data. Auxiliary data is encoded by modulation of a video signal, thereby creating a composite video signal consisting of auxiliary data and continuos video program data. The composite video signal is transmitted to and displayed by a display device. The preferred method of receiving auxiliary data when the hand-held device is a smart card is by optically detecting and extracting auxiliary data on tne smart card. The user first positions the optical receiver of the smart card so that it is capable of receiving video signals from tne display device. The smart card, when actuated and appropriately positioned, begins receiving video signals. Circuitry on the smart card discriminates whether auxiliary data is present in the video signals (i.e., where the video signals received are composite video . If auxiliary data is present, the hand- neld device reproduces the auxiliary data for its use. The preferred method of receiving auxiliary data when the hand-held device is a mobile phone or PDA is by detecting and electronically extracting the auxiliary data from the video signal by use of a decoder box. The decoder box has circuitry that determines whether auxiliary data is present in the video signal. The box then transmits the reproduced auxiliary data to the mobile phone/PDA by RF, IR, PCMCIA, or wire transfer. These methods of data transfer are faster and more reliable than optical transmission, and reception data may then be transmitted faster. The box preferably receives the video signal from its source by use of RCA jacks, but may otherwise receive the data through other methods such as through use of super VHS, fire wire, or coaxial means, or may be connected to an RF antennae, integrated into part of the circuitry of the television, or be connected so that the decoder device can receive the video stream. The auxiliary data, when present, is transmitted from the decoder box to the hand-held device. Transmission tc the nand-held device occurs preferably through RF, so that the hand-held device need not be aimed at or physically connected to the decoder. However, other various methods including IR transmission and direct connection through a computer interface such as a PCMCIA port are likewise capable of receiving transmissions from a decoder box. The decoder box may also function as a two-way device, and may receive information from the mobile pnone/PDA. The decoder box may, with an appropriate graphics rendering unit, display information received from the mooile phone/PDA on the screen. As an alternative to or in addition to the mobile phone/PDA having networ< access, the decoder POX may alternatively contain networκ access. The decoder box may additionally contain means to control various devices sucn as the VCR. Users, upon receipt of information sucn as a televisic schedule on their nanα- held device, may transmit a reαuest to the decoder POX or VCR to schedule recording of a television program. It will be appreciate in the art that although the optical metnod is preferable for smart cards and the electrical method is preferred for mobile pnones and PDAs, both methods are interchangeable and may be used for any handheld device under the present invention. Among the several methods nerein described may be noted a method of video interactive advertising and promotion, comprising normal television programming content modulated to contain auxiliary data, wnere tne auxiliary data is associated witn a sponsor and carries information of special significance relative to the sponsor and of special value to television viewers, distributing interactive devices of nand-held character to television viewers for their use and convenience, the devices being capable of selectively receiving auxiliary data or receiving and decoding composite video signals, providing incentives for viewers to use the interactive devices for obtaining the auxiliary data by rewarding the viewers with mrormation of special value, the interactive devices being capable of retaining indication of naving received the information, and providing redemption of the special value for users at a redemption site where users may present the interactive devices. When auxiliary data is reproduced by use of the card, various possible signals, indications, display readouts, or other interactive events provide the user with a benefit according to content of the auxiliary data. For example, a series of electroluminescent (ELj indicators may operate m sequence to signify coupon value. A LCD readout or other visual displaying device may present information to the user or give notice of value received. Bonus points may be collected and retained on tne device. Text, code, or other data ma;, be transferred to a connected computer for which information may be displayed or executed on that computer. In a use of the device m conjunction with a sports presentation, users mav receive on the hand-held device' s alphanumeric display current sports statistics, including exemplarity, a batter's batting statistics. In a use of the device m conjunction with a car racing presentation, users may receive on the hand-held device's alphanumeric display the lap data, position, speed of a race participant, or other statistics from a racing event. Such statistics may be delivered in real time or delayed. In user of the device in conjunction with hotel access, additional access to rooms and facilities may be available for tne user, of whicn an indication may appear on the LCD. The hano-held device may have additional capabilities for promotion and interactivity which are preprogrammed or programmed via user input. Such capabilities may include demographic or user information, which may be used in various applications of the nanα- held device by a user or sponsor of the device. The hand-held device may also be used to make or facilitate purchases of items. The design of the hand-held devices are typically m the shape and form of smart cards, palm devices, or mobile pnones. The exterior design of the hand-neld device may contain indicia of recognized athletes, teams, products or other figures, and the collection of data located on the card entice users to save, collect, and trade the cards, such as m a rotisserie league. Additionally, other nand-manipulable devices of a similar size and nature that are capable of receiving and processing auxiliary data as described nerem are also within the scope of this invention and may receive data by either the electrical or optical metnods as appropriate or as is desired. Thus a stuffed animal or toy, snapshot-type camera, replica sports helmet, scaled racing car, or a replica baseball bat with proper circuitry may process the data as a nand-neld device of the nature described herein. Another feature of the present invention s an optional computer interface port. The nand-held device facilitates transmission between the device ano other hand-held devices, computers, and other computer-like devices. In promotional applications of tne hand-held device requiring Internet access, if the device cannot transmit data and information through the Internet directly through wireless means or other direct connection to the Internet, it may connect to the Internet through use of a computer interface port. Television viewers, upon watching commercials, programs, or movies, use the hand-neld device to obtain opportunities for e-commerce or informational purposes. The information may then transferred to computers or computer-like devices where it may be used for informational or promotional opportunities. For example, a talk show may have a discussion about endangered animals. Informational or promotional opportunities such as available books or videos relating to those animals, along with information relating to how viewers may learn more information from a given Internet website, are transmitted m composite video signals received by the hand-held device. The opportunities are transmitted as the content of the auxiliary data with the composite video signal, and when the hand-held device is a PDA or mobile phone, is preferably electrically detected and discriminated by a decoder box, and then transferred by RF to the hand-held device for its use. The auxiliary data may also be transferred by other known means including by IR and through direct wiring. Alternatively, the auxiliary data may be optically detected and reproduced by the hand-held device, wnich is the preferred method of receiving the auxiliary data when the device is a smart card. As a further alternative, the auxiliary may be detected either optically or electrically, and then transferred to and discriminated by hardware or software of a connected computer or computer-like device. In some of the promotional applications, the opportunities are transmitted with the composite video signal and are preferably optically detected and reproduced by the hand-held device and then transmitted to a computer by an interface. However, the auxiliary data may alternatively be electrically detected by a decoder device, transferred to the card and discriminated, and then transferred again to a computer via an interface. As a further alternative, received composite video signals may be transmitted from the hand- neld device to a computer by an interface, where the auxiliary data is discriminated and the opportunities are then detected and reproduced by the computer. By any of the methods described herein, tne opportunities once available to the computer can oe stored and used, such as for e-commerce or information collection. When appropriately connected, the stored information from tne computer-interface card is uploaded (when appropriate) to a computer for processing and fulfillment. The information received by the computer includes a web page, Internet address or Uniform Resource Locator ("URL"), Hypertext Markup Language ("HTML") or similar textual information or code that can be displayed to or executed for a user. This information provides a means for the user to obtain benefits through interactivity, and for the sponsor to provide promotional information to the user. Devices and methods are provided under this invention which allow an electronic coupon to be redeemed at a point of sale using existing point of sale "(POS") hardware and software. In addition, the coupon can be configured to be used only once and with a reasonably high degree of security. Furthermore, check out time is not seriously degraded and multiple coupons may be redeemed at the same POS with relative ease. One method of using the card at a POS, involves the user giving the nand-held device to the casnier. The casnier then locates the correct coupon or redemption value on the hand-held device using a scrolling function in combination with the LCD. The hand-held device is then held such that tne LCD is facing towards the cashier and the photodetector faces the bar code scanner. The "redeem" button is then pressed, and the photodetector on the hand-held device passes over the bar code scanner. The timer in the hand-held device resets the device to non-redeem mode if a scan is not detected within thirty seconds. When the scanning laser light is detected by tne hand-neld device, tne device beeps and a numeric cooe is displayed which may correspond to a stock keeping unit (SKU) number or other information regarding receipt of product shipment, inventory, and/or stocking. Other codes, including an additional numeric code such as the serial number of the hand-held device or a security code can also be displayed. The cashier then enters the numeric code or codes and the appropriate discount or value is applied to tne purchase of the consumer. The timer may also delete the coupon if the hand-held device is scrolled to the next coupon, or if the device is powered down and tnen powered up again. The coupon may also be erased either automatically or manually by pressing predetermined buttons on the hand-held device. Various other methods of the invention are set forth in the following description and claims. Similarly, other objects and features will be apparent or are pointed out more particular herein below.

Description of Inventive Embodiments Referring to FIGS. 1-3, m a system of the invention, and in accordance with tne various methods nerem described, composite video signals are received and projected oy a display device 10, to be received by a first embodiment of an interactive hand-held device of the invention 12. Display device 10 is representative of a television screen, video monitor or other video display, movie screen, computer monitor, video-converted display or video-like display, capable of receiving analog or digital video or video-representative signals from a suitable source, sucn as a television transmitter, a videotape, streaming video servers, a Digital Versatile Disc ("DVD") , or the computerized display representation of such a source of image content. For present purposes, however, it will be assumed that display device 10 is a kinescope or other conventional type of television display or monitor (whicn may, of course, include multiple or single-beam types of projector displays). Thus, display device 10 may schematically represent a video display for displaying video signals but may alternatively be any sort of electron gun, active, array or passive array display device capable of providing not only imaged information in a visible mode but also auxiliary information (e.g., data) in a suostantially transparent mode. Display device 10 may be further characterized as a computer monitor or display, as well as a portion or window of such display device. Display device 10 may also be a nigh definition or digital television, or other digital video presentation device. Video signals include tnose delivered by microwave relay, satellite retransmission or cable, streaming and other types of downloadable or viewable computer video presentations, and tnose generally made available oy wired or wireless methods.

Housing 14 may be of any hand-held shape desired that is functional and hand manipulable, examples of which include a PDA (as shown) , cell phone, PCMCIA card, snapshot-type camera, replica sports helmet, replica baseball bat or football, or scaled racing car. On front surface 16 of hand-held device 12 is an imprinted brand name of a sponsor 17, and possibly information or indicia that may induce a user to associate device 12 with a particular sponsor 17. When hand-helo devices 12 are inexpensive to manufacture, such as when they are in the form of smart cards, imprinted sponsors 17 may be found with higher frequency. However, when hand-held devices 12 are the user' s personal device such as a cell pnone or PDA that have primary uses otner than receiving promotional opportunities, such indicia may not be included. Sponsors 17 may include various entities such as advertisers, Internet websites, television shows, other occurrences, programs or events, for which use of the device will provide interactive opportunities. Sponsor 17 may be a company providing the hand-held device 12 to a user of its service, such as a hotel, phone company, PDA service, or place of business, that uses device 12 for access, privileges, and/or rewards . A leading edge 18 of the hand-held device 12 in PDA- like shape may include an RF antenna 68 to receive auxiliary data as is described herein below. Visible from front surface 16 of the device is a visual display 20, of which alternatively or additionally may be light- admitting diodes or other electro luminescent light sources 20a, 20b, 20c, and 20d as shown in FIG. 2B. Handheld devices 12 have various users controls and may include a keypad or touch screen (not shown) to allow user input for specific functions and additional uses. Hand-held device 12 is depicted as a smart card in FIG. 2C in a manner in which it may be held and used. Hand-held device 12 includes a credit card or wallet- card-sized housing 14 that encloses various circuits and circuit components ("Circuitry") of the device.

Housing 14 may be of any hand-held shape desired that is functional and hand manipulable, examples of which include a PCMCIA card, snapshot-type camera, replica sports helmet, or scaled racing car. A leading edge 18 of hand-held device 12 may include a lens or small aperture 36 to admit video signals to a photosensor within housing 14, as is described herein below. Visible from front surface 16 of hand-held device 12 are a plurality of light-emitting devices 20 which may be light-admitting diodes (LEDs) or other electro luminescent light sources, including, for example, regions of a LCD of either active or passive type. A typical manner in which hand-held device 12 is used and the lignts are operated is as follows: A user watches a television presentation such as a commercial, television program, movie, or other video-displayed program. When such a presentation is displayed, the user may then hold hand-held device 12 device as shown m FIG. 2B or 2C. The user positions hand-neld device 12 so that leading edge 18 of device 12 will be in a position for receiving video signals from display device 10. Handheld device 12 or display device 10 may have indicia informing the viewer to press tne pressure membrane or button 22 at a preferred time, such as when a commercial of a sponsoring entity appears. Although the term "button" is used herein, it is considered to include memprane switches, pressure or touch regions capable of activation and carrying out tne function of a button. Wher the user presses outton 22, the video signal will De detected and received by a pnotoαetector (the process to be described below) witnm housing 14. The composite video signal comprises a video signal modulated with auxiliary data, m accordance with the teaching of the above-referenced Broughton and/or Ciardullo each of which are nerein incorporated by reference. A discriminator, implemented by circuitry of hand-neld device 12 determines whether auxiliary data has been transmitted along with the video signal of t π e presentation. However, the video signal may be received by a decoder box which then discriminates the auxiliary data and transfers it to the hand-helα device 12 by RF or by other means including IR or a computer port and direct wired connection. The received video signals may be sent through an interface (to be described below) of the hand- helα device 12 to a computer or computer-like device where the discrimination of auxiliary data may De implemented in the computer's hardware or software. If the discriminator determines that the transmitted video signals contain auxiliary αata or auxiliary data is received, the circuitry of the nand-held device 12 may then cause an audio transducer 34 present on the printed circuit Doard to sound a tone or "beep", providing assurance that the auxiliary data has been received satisfactorily. A suitable aperture may be provided on the front or rear surface of hand-held device 12 to allow sound to pass from audio transducer 34. Hand-held device 12 may contain more advanced means of providing sound to a user. Hand-helα device 12 may contain advanced sound circuitry so that the device can play digital audio signals comprising songs or instruments. The songs may be prerecorded to hand-helo device 12 and may be triggered upon proper notice, or they may be downloaded in delayed or real-time and thereafter be played. Thus, versions of hand-held device 12 that are capable of music may synchronize songs through multiple devices by transferring and receiving information from the other devices 12, aiong with optional source of the auxiliary data. The circuitry of hand-held device 12 may also cause operation of one or more of lights 20a, 20b, 20c, and/or 20d of FIG. 2B or FIG. 2C, to indicate a value (whether it be a discount, prize, coupon, or item) that has been received. For example, one light 20a may entitle the user to a free beverage at a sponsor's store location. Two lights 20a and 20b may indicate a substantially larger coupon value, such as a twelve-pack of a beverage. A coupon value causing three lignts 20a, 20b, and 20c to be illuminated may indicate entitlement to a grand prize, such as a free supply of a beverage for the lifetime of the user. The term "light" is intended to mean any kind of display useful for conveying a signaling or indicating purpose visible to the user. It is also possible to use the lights 20a, 20b, 20c, and/or 20d of FIG. 2B or FIG. 2C m alternative methods to confer benefits from reception of auxiliary data. For example, different colored lights 20 may De used with each color representing a different prize or different value. Alternatively, hand-held device 12 may be programmed to operate so that a light 20 shows each time a different commercial of a sponsoring entity is shown, so the user will have inducement to watch multiple commercials to be entitled to a prize or benefit. The hand-held device and lights 20a, 20D, 20C, and 20d operates in tne following manner: During a commercial or at the appropriate time, a user pushes button 22 to receive video signals by a preconfigured hand-held device 12. If the appropriate auxiliary data was present in the received vioeo signal, hand-neld device 12 then validates the receipt of the auxiliary data by illuminating a first light 20a. During a furtner commercial a second light 20b illuminates. During a third commercial a tnird light 20c illuminates, and during a fourth commercial presentation, light 20d illuminates. The user may then appropriately present hand-held device 12 at a vendor location, redemption center, or Internet website to determine if the device is one for which a special prize is to be awarded. If handheld device 12 does not entitle the user to the special prize, a consolation or alternative prize may be made available. A different variation of illumination of signal lights 20a, 20b, 20c, and/or 20d may entitle tne user to alternate consolation or other prize. Alternatively , the lights may work in tne following manner: During each quarter of play, when a commercial appears the user may press button 22. When auxiliary data has been successfully received (by the process of wnich is described above) from the commercial sponsor 17 of an event or of hand-held device 12, the first light 20a will be illuminated to indicate receipt of the commercial during the first quarter. Such operation will continue through successive quarters until all lights are illuminated. Tne user may then present hand-held device 12 to a store or point of sale operated by the commercial sponsor 17 to receive a prize or grand prize, depending upon the configuration of device 12. Or, the user may be rewarded in accordance with how many lights 20 are illuminated. Then, the user may thereafter tender hand- held device 12 for value redemption, or may present it, for example, at a lottery at which the devices 12 may identify the user's name by users, and where the device 12 is drawn. The store location, point of sale, or sponsor's website may include means for resetting hand-held device 12 so that it may be used again in a similar manner during a future presentation. Such means may include leaving indicia of a previous award reception on hand- held device 12, such that a user may only redeem their benefit a limited number of times or for a limited duration. Hand-held device 12 may have a code on the back such that a redemption center may verify that the receiver of the benefits of device 12 was in fact entitled to receive them and that device 12 has not been modified to receive an unauthorized benefit. It will be appreciated from the foregoing that viewers using hand-held device 12 may be induced to watch a presentation that they might otherwise not be so inclined. The inducement may span a series of commercials, causing users to watch presentation after presentation, as during successive days or weeks. Also, advertisers may make a better determination as to who has been watcmng and paying attention to their commercials. When users return or bring in nand-held device 12 to the benefit redemption center, advertisers will have knowledge of now many people actually took advantage of the promotion. The hand-held device 12 not only induce the viewer to watch a commercial, but also induces viewers to visit a sponsor's place of business, point of sale, or Internet website at which they may receive the value indicated by hand-held device 12 indicated by a visual display 20 such as the lights 20a, 20b, 20c, and/or 20d or a code displayed by LCD 44 of hand-held device 12. Another example of use of hand-held device 12 is as follows: On a television broadcast, the announcer discloses last minute air fare specials indicating available flight times and cost. The video signals are modulated to contained auxiliary data with flight information. Interested users capture the auxiliary data containing their selected flight opportunity. After receiving tne data, users may view the opportunity directly on LCD 44 of the hand-held device 12, or alternatively be provided with a special Internet link to the opportunity. Users with Internet access may purchase the opportunity directly, for which they may receive a confirmation for the ticket purchased. Users without network access may connect hand-neld device 12 to a computer with Internet access to access the airlines Internet weDsite, verifying tne availability, the cost, tne flight information, and the restrictions to complete their purchase. Alternatively, users may be required to arrive at the airport on a first come first served oasis to complete their purchase and take their flight much as a last minute stand-by passenger makes a ticket purchase. There are various incentives for a user to watch a sponsor' s televised presentations including commercials, which include amusement or information of value to the user. For example, during eac.n quarter of a game, a user would view commercials to oDtam an indication of participation by means of lignts 20a, 20b, 20c, and/or 20d during the successive quarters. The user knows they may take nand-held device 12 to a POS operated by tne sponsor and receive a prize for having watched. Common advertising strategy for sponsors of major sport events, such as "bowl" games, is to provide a presentation during each quarter of the game. During nationally-televised "super" events sucn as tne well-known Super Bowl, World Series and "bowl" games, increased viewer ratings induce advertisers to provide impressive commercials to whicn users will not only pay attention but will also interact, watch, participate, and be favorably impressed Dy sucn commercials. Hand-held devices 12 when used during such televised presentations offer advertising sponsors an unparalleled opportunity for promotional activity and for assuring audience participation, as well as providing an exceedingly effective methodology and means by which the percentage of successful viewer watching and product/service interest may be measured. Multiple advertisers may use hand-held devices 12 for either the same event or for multiple events. For example, if a commercial is presented during a television show relative to a first sponsor's product 17 or service (such as relating to automobiles) with which there is a relation to a second sponsor 17 (such as bank providing financing for the sale of tnose automobiles), nand-held device 12 may be especially adapted by its resident instruction set to be "co-branded, " so as to respond to Dotr. sponsor's presentations. The co-branded hand-held device 12 may be used to provide special inducement such as through a prize or other value upon presentation at a bank, a dealer, or Internet website affiliated with or sponsoring the commercial presentations. Many other co- branding possibilities for hand-held devices 12 and their usage will be evident. FIG. 4 illustrates features of hand-held device 12, including the provision of aiming light 24 on the face of the nand-held device. Aiming light 24 is typically included on embodiments of hand-held device 12 where video signals are optically received by device 12, such as to indicate that device 12 is positioned such that it is capable of capturing video signals emanating from a display device 10. When button 22 is pressed while the leading edge 18 of hand-held device 12 is generally oriented toward display device 10, received composite video signals cause illumination of aiming light 24 to indicate that video signals are being received. Aiming light 24 illuminates for so long as data is being received, for a predetermined period of time sufficient to indicate that hand-held device 12 is oriented or aimed correctly, or for a long enough time period as to enable the encoded signals to be received by device 12. Aiming light 24 may be included on embodiments of hand-held device 12 where the video signals are electrically received to alert the user that auxiliary data is being received through IR, RF, or the computer interface. Referring to FIG. 5, the internal features of handheld device 12 are illustrated. They may be seen to include a printed circuit board 26 having integrated circuits 28 including push-button 22 and aiming light 24, which may for example be a LED. The circuit board includes at an appropriate location, an optional photocell 30. Pnotocell 30 is appropriately oriented so that it may receive light through a suitable aperture 36 (not shown) along leading edge 18 of hand-held device 12, which aperture 36 may be at a location as snown in FIG. 3. The circuit is powered by one or more batteries 32 or other suitable cells (not shown) , intended to provide sufficient power for operation of hand-held device 12 for days, weeks, months, or years. Batteries 32 may be used with other similar sources of portable power (not shown) , such as solar cells. It will be appreciated the electronics of a PDA, cell phone, or other computer-like device capable of processing auxiliary data as described herein may contain significantly more electronics to provide functions to herein described that to relate to the other functions of hand-held device 12. Three lights 20 are shown present on the circuit board, and they make take the form of LEDs . However, as will be understood from study of FIG. 14 the circuit may include provision for more than three sucn lights. For example, it may include circuits for energizing up to Referring now to FIG. 6, an embodiment of the handheld device 12 devices is shown including the provision for an LCD 44. LCD 44 may be a textual display consisting of 16 digits, but less or more display capability may be provided, based on need and usage. Alternate LCDs 44 capable of presenting the graphic content in monochrome or color, however, are preferably used. Hand-held device 12 has an power button 38 which when depressed will initiate operation of an LCD 44 to display a coupon, a prize notification, or other information indicating receipt by the device of auxiliary data. For example, LCD 44 may used to display a first coupon m a circularly linked list of offers. Power button 38 may also held to initiate receiving video signals, or may be used for other αisplay or control purposes separately from button 22. Scroll button 40 allows a user to traverse, i.e. scroll, information retained or received by hand-held device 12, for example, the circularly linked list of offers received and stored on the device 12. It will be appreciated that any of the various buttons 22, 38, 40, or 42 may be implemented by using other buttons with other functions on hand-held device 12, such as the numbered buttons on the cell phone or shortcut buttons on the PDA. It will furthermore be appreciated that these buttons 22, 38, 40, or 42 may be implemented via touch screen, sucn that there is no physical button 22, 38, 40, or 42 on the device. The expiration button 42, at any t me while viewing an offer, when pressed displays the expiration date of the coupon value and when released shows the original offer again, or alternatively switches between the different displays. The expiration button 42 may display the date of hand-held device's 12 expiration, after which the device will no longer function or will have reduced functionality. The expiration button 42 may display the expiration of a program or function of the hand-held device 12. The functions and programs of hand-held device 12 may be reused until expiration, and such reuse may include watching various games during a season, watching all quarters or periods of play, and watching appropriate commercials. As a further alternative, expiration button 42 when depressed or depressed m conjunction with other buttons 22, 38, or 40 may additionally display data information about where hand-held device 12 was issued to the user, where the user lives, a serial number, and other data that a sponsor may desire. The displayed data may also identify the holder of hand-held device 12 and may have a number, personal identification number, or other data personal to the holder, such as residential address. It may be desirable or necessary to disclose to the user the extent to which such personal information will be collected by use of hand-heiα device 12. Accordingly, when hand-held device 12 is used at a redemption center, such as a point of sale, Internet website, or restaurant operated by or on behalf of sponsor 17, a benefit may be received by the user. Information about the user, Dased on data stored on the device, may then made available to the sponsor, merchant or other seller of product or service. In that way, the sponsor 17, merchant or other seller of product or service may learn about their customers, possibly adding the user's name or address or additional information about the customer to a customer base. Offers received by hand-held device 12 may be indicated not just by illuminating the light signals 20, but by textual information and graphics displayed on LCD 44. Auxiliary data may contain offers which includes instructions or identif cation of the redemption location. The text may otherwise identify the product or discount or other coupon to be redeemed by the user. For example, hand-held device 12 may be used m a mode in which the device receives composite video signals which trigger preprogrammed offers that already exist m a lmκed list stored on the device 12. After watching a commercial, auxiliary data causes hand-held device' s 12 preprogrammed textual information to indicate a product, discount, or other coupon available until an expiration date. Hand-held device 12, upon receipt of auxiliary data, retrieves the information and makes the offer available to the user. Alternatively, the information may be received by handheld device 12 during use and then decoded and displayed on LCD 44 as well as being added to the linked list. Hand-held device 12 is useful to store multiple offers. Multiple offers may be from the same sponsor or different sponsors 17. The received offers may be valid for certain different amounts and for varying periods or dates. Tne nand-held device 12 may also be able to store previously received offers so as to indicate that a user will not be able to reuse tne , as for example in the case of a prize or other one-time benefit. Items displayed on LCD 44 are coupons which provide offers, coupon values, validation for discounts or other user benefits, such as prize merchandise identification or location for redemption. When hand-held device 44 is taken by the user to a redemption site, such as to the sponsor 17, merchant or other seller of product or service center, items stored on hand-held device 12 may oe cleared by an authorized procedure at the redemption location, but alternatively the stored items or coupons may be reused until an expiration date. The coupons may contain tne date the commercial originally ran, or the date the coupon was received by hand-held device 12. In other words, the auxiliary data may have an encoded date stamp, or the hand-held device 12 may date stamp the information received. The date information may inform mercnants or sponsors of the least or most effective showings of their commercial. It may also be desirable to purchase items from the use of nand-held device 12. Hand-neld device 12 may store purchasing information, such as the numbers of one or more credit cards. This feature may be used, for example, when nand-held device 12 is capable of receiving multiple offers. After such an offer is downloaded to hand-held device 12, the user connects the αevice to the Internet Dy any of the methods described herein. The user selects the offer, and selects to purchase the discounted item. The stored credit card ana snipping information are transferred through the Internet to carry out the transaction. Hand-held device 12 may also store other data sufficient to make purchases, such as debit card or online wallet service information. FIG. n shows circuit features of tne card embodiment of hand-neld device 12 without housing 14. LCD 44 is evident, as also controls 38, 40 and 42, ana a pair of batteries 32 are located at the right siαe of tne circuit board. FIG. 8 shows a chart of an alternate embodiment of hand-held device 12 having an input-output means preferably in the form of a Personal Computer Memory Card International Association ("PCMCIA") interface, such as may commonly be found on a laptop computer. PCMCIA interface 70 connects with PCMCIA connector 72 to transmit information to and from a computer or computerlike device. Connections of PCMCIA interface 0 to a computer are preferably made by a PCMCIA port, out the connection means may alternatively be through other known computer and computer-like slots, connections, and ports such as Ethernet, Token Ring, mfrareα ("IR"), RF, Small Computer System Interface ("SCSI'" 1 , Universal Serial Bus ("USB") , parallel port ("Parallel") , serial port ("Serial"), IEEE 1394 FireWire ("FireWire", , S/PDIF, AES/EBU, fiber optical cable, and Apple Desktop Bus ("ADB"). Hand-held device 12 may also utilize portable data storage, such as flash memory, mini-disc, or stick memory, to manually transfer information from hand-held device 12 to a computer. The types of connections used in various applications of hand-held αevice 12 vary based on factors including cost, transfer speed, and acceptance by users and industry. Hand-held device 12 while preferably connected when applicable to a computer, may also De connected to computer-like devices or other devices capable of processing information transferred or executing functions from an computer-interface device. These devices include PDAs or other palm top PCs, cellular phones, and other hand-held net-connected or computer-lικe devices. The hand-held devices preferably have wireless Internet access, which allows for instant Internet transactions without utilizing a computer or computer-like device. As with various other embodiments of hand-held device 12, composite video signals are preferably received by electrical means, snown herein shown as by an RF antenna 68. The power and functionality of the handheld device are increased by additional RAM 51 connected to the microprocessor 50. The power system of the handheld device, comprising battery 32, optional solar panel 33, and the power control 31 adequately provide the power needed for processing and interfacing with the various devices. Composite video signals may also be received by photocell 30, herein shown as a photodetector 30a and an optical receiver circuit 30b. Preferably, the video signal is received electrically from display device 10, the auxiliary data is decoded, and transferred to hand-held device 12 by RF means. Alternatively, the video signal received by the device may be discriminated by the microprocessor 50 of hand-held device 12. As a further alternative, hand-held device 12 may receive the video signal by optical or electrical means, and transfer the received data through the PCMCIA interface 70. If the received data is processed on a computer, the computer may act as a discriminator, determining when auxiliary data is present and handling it appropriately. The data also may be sent back to hand-held device 12 for further processing, promotion, or information opportunities. When the received data is not sent immediately through PCMCIA interface 70, the data is processed as m other embodiments described herein. A preferable but optional visual response by LEDs 20 or LCD 44, promotional data may oe available to the user' s computer upon connection of PCMCIA interface 70 with the computer by the PCMCIA connector 72. Sucn promotional data includes Internet website or addresses, textual information and code, audio, and visual files. Upon receiving the data either by RF antenna 68, optical detector 30, or by PCMCIA interface 70, hand-held device 12 may display an appropriate confirmatory message on LCD 44 or may otherwise notify tne user of the reception of data . An example of use of hand-held device 12 is as follows: A store or sponsor 17 issues a hand-held device 12 to a child, or otherwise providing the child witn means to interact such as by providing a downloadable program from an Internet website to be used on a cell phone, PDA, or smart card. During cartoons or at other times when children are likely to watch television, a television program is displayed which contains modulated video signals. The program advertises a product sold by stores or created by a sponsor. The cniidren are instructed to use their hand-held device 12 to tell their parents what toy they want for their birthday, holiday, or other special occasion. After capturing the auxiliary data containing information or product data, the children give hand-held device 12 to their parents. The parents may tnen review the product selected by the child, and purchase the product or services directly if the device has Internet access. If hand-held device 12 does not have Internet access, the parents may connect the hand-held device 12 to their computer with Internet access and purchase the toy or toys directly from sponsor 17, online from an Internet store, or from a store suggested by a representative of sponsor 17. The toy will then De shipped to the location specified by the user, for whicn the information may be preprogrammed by the user. If hand-neld device 12 has wireless Internet access and a stored credit card and shipping information, the parents may simply enter an approval code and purchase the product with little effort. Alternatively, the parents may bring hand-held device 12 into a store, or send it m to the store or sponsor 17, so that the order can be processed and fulfilled. Thus, parents may purchase the toys desired by their children with minimum time and effort. It will be apparent that hand-held device 12 could alternatively be used m a manner similar to a bridal registry, where the selected objects are not purchased, but are instead listed online on a gift registry. Thus, people who desire to purchase toys for the child will know what they child wants. Another example of a use of hand-held device 12 is as a loyalty device which stores bonus points in the memory of device 12 and/or at a remote location such as a central computer. Hand-held device 12 stores bonus points for television shows or movies watched containing auxiliary data with bonus point values. Shows may require the user to obtain tne auxiliary data at the beginning, during, at the end, multiple times during tne show to receive the bonus points for watching the show. Users may receive additional bonus points by purchasing VHS or DVD movies, movie theater tickets, or merchandise. Users may receive additional bonus points by visiting the sponsors' Internet websites, and even more for exploring their weosite and maκιng online purchases. Users may receive even more points by responding to quizzes, questions, and surveys after television shows or movies. Users may interact by using nand-held device 12 to select their answer, and eitner upload their answer through the Internet, or verifying their answer upon review at a store. Users may earn additional bonus points by trying out specific restaurants related to the sponsor or, if at an amusement park, for rides and shows sponsored by tne sponsor. Thus, users have various opportunities to amass bonus points from many various sources by a sponsor or groups of sponsors. FIG. 9 is another embodiment of the hand-held device 12 with an input output interface m the form of a PCMCIA interface 70 and docking station 76 as shown. The docking station 76 may receive discriminated auxiliary data or composite video signals and transfer it to hand- neld device 12 by PCMCIA interface 70. Alternatively, docking station 76 may contain optics, which may be used to optically detect tne video signal from a display αevice 10. Then either the entire video signal may oe transferred to hand-held device 12 so that device 12 can discriminate the auxiliary data, or the docking station 76 itself can discriminate the auxiliary data and transmit the auxiliary data to the device. The data may then be transmitted to hand-held device 12 by IR, RF, or by PCMCIA interface 70. Docking station 76 may charge the battery 22 by its battery charging control 80. Docking station 76 may implement various device functions and advanced device functions by controlling hand-held device's 6 microprocessor 50 tnrougn the interface drive 78. The hand-held device 12 in FIG. 10A be termed a camera card 12C, as it is similar to other αevices 12 described herein, yet configured to simulate and suggest to the user the appearance of a small snapshot-type camera. Camera card 12C includes housing 14 in the shape of a small camera, and a lens or lens simulation 36 suggesting use of the camera-like hand-neld device just as a user would use a snapsnot camera, to take a "picture" of tne display device 10. Camera card 12C includes a simulated lens 46 either imprinted, embossed, molded, or otherwise extending slightly above the surface of a camera-like housing 14 so as to present a more realistic simulation of a camera lens. The data- receiving photocell 30, when present, collects information in the same manner as previous embodiments using optical detection, and may be located behind simulated lens 46 or beneath a suitable aperture 36. Button 22 when depressed and released simulates the shutter of a camera. Thus, it causes camera card 12C to receive either composite video signals or auxiliary data (depending upon the method as described above) until such collection is complete, thus the user simulates taking a snapshot or picture. A viewfmder 49 is provided tne form of an aperture extending through housmσ 14, suggesting that a user aim at display device 10 through viewfmder 49 as they would on a real camera. Viewfmder 49 need not have any special accuracy or lenses, as its primary purpose is to simulate the look and feel of a camera. Camera card 12C will operate properly when its surface containing photosensor 30 is oriented toward display device 10, and its orientation need not be precise in the sense of a camera but only approximately directeα toward the source of video signals. Photosensor 30 may be positioned behind lens simulation 46 or elsewnere for suitable sensitivity to video signals emanating from display device 10. Other nonfunctional decorations (not shown) may be provided with camera card 12C to make further suggest to the user that they are taking a picture. Examples of such include a wrist strap attached to the camera, a camera case, an audio transducer tne circuitry of the camera card to make a clicking sounα, or a flash. FIG. 10b shows the reverse face or side of camera card 12C. It has controls and display features similar to those shown in FIG. 6. A difference is that enabling button 22 may be located along a top surface or edge of the camera. Camera card 12C is intended to allow users to better conceptualize the process of receiving composite video signals from a display device 10. Use of camera card 12C may also provide other unique and fun opportunities such as pretending to take pictures and receiving such offers as previously stated. FIG. 11A is the front of another version of the interactive hand-held device that may be termed a racing card 12R. On the front of racing card 12R is simulated lens 46, of a size smaller size than that of the camera card 12C, enabling more promotional information to appear on tne front of card 12C. The promotional information may show or describe the racer or event (s) that the card can be used for or otherwise promote holder usage. FIG. 11B shows the reverse face or side of racing card 12R. It has controls and display features similar to those shown in FIG. 6. A difference is that the enabling button 22 may be located along a top surface or edge of racing card 12R. Racing card 12R is configured to allow users to better conceptualize the process of optically receiving composite video signals from display device 10. The racing card 12R may also provide other unique and fun opportunities to the user such as receiving driving statistics and various offers and information as previously stated. FIG. 11C shows the front side, i.e., user-opposite surface, of racing card 12R, with the user preparing to receive composite video signals by means of card 12R, and where the user is aiming card 12R toward display device 10, by sighting through viewfmder 49. The racing card 12R has control and display features like those illustrated in FIG. 11B or 11A. As racing card 12R is used, auxiliary data may be received which may either update or replace that which is stored in memory of the card. Also, as scroll button 40 is depressed, more data than tnat displayed by LCD 44 may scroll across. For example, racing card 12R may have stored within its memory information about a race, a racer, or other information relative to the event. It may include, for example, previous performances, standing of the racer, and biographical information. To provide a suggestion of the use of the racing card 44 and to enhance its attractiveness for users, especially young users, a reproduction of a racing car steering wneel and instrument grouping may appear on the surface of the card, adjacent the LCD 44, as shown. Turning to FIG. 13, a version of hand-held device 12 which may be termed a "sports" device 12S is shown. It includes housing 14 which is provided with front surface 16 which may include a visual field 54 for bearing the image of a sports contestant. In addition, a LCD 44 is provided together with button 22 which allows the user to initiate operation of hand-held device 12, preferably with an RF antenna 68 oriented for receiving RF signals, or alternatively for optically receiving composite video signals, such as by noldmg hand-held device 12 so that leading edge 18 is generally towards display device 10 presenting a program relating to the sports celebrity or other person depicted on display device 10. Update button 56 is pressed when user desires to obtain some current information, such as the current statistics of the player depicted on sports device 12S. In operation, sports device 12S may be designed to receive only information relating to the player depicted on the device 12S, update that player's statistics, or add to information about the player already stored in memory of the device, any of which may then be scrolled across LCD 44 by pressing scroll button 40. Use of sports device 12S is as follows: display device 10 near the user presents a professional sporting event, such as a baseball game. When the sporting event's participant Decomes the focus of attention, such as a professional baseball player coming to bat, button 22 may oe actuated. An aiming light 24, if present, may illuminate, or instead LCD 44 may initiate a readout of its newly received statistics associated with the depicted player. For example, the readout may identify his name, his batting average, the number of home runs hit, games playeα, number of times at bat, and his runs batted- average and number of stolen oases, with the statistics updated each time such a player is at bat. The statistics may be sent to a computer through an interface (as described above). A memory of sports device 12S may include such statistics in a non-volatile from which the device 12S is enabled to update the statistics each time the player comes to bat. Auxiliary data associated with an at-bat occurrence received by the sports device may contain information associated with tne player, sucn as his current statistics. As play continues, received auxiliary data may include updates for those statistics Dased upon the experience of the player at bat. The information is stored in a circularly linked list of data and may include various statistics from different games that the player has played in, various statistics over multiple years for this player; or if this device 12S is for use in watching an entire team, for instance when sponsored by the owner of tne team, it may contain different information or various members of the team. For example, as a celebrity batter is taking his turn during a baseball game, the television viewer directs his sports device 12S at display device 10 to receive composite video signals, or preferably configures his device so he may electrically receive the auxiliary data. In both cases, the viewer receives real time statistics about his favorite athlete during the telecast via his interactive sports device. Additionally, the user of a sports device 12S at a live sporting event may receive information without the use of a display device 10 , such as by RF or IR. Thus, sports fans may get live statistics and trivia through their nand-held device 12 while they watch the game live. Therefore, fans with obstructed views or sports fanatics may obtain additional information and have fun while enjoying a live sporting event. The information received by the sports device 12S may take many forms including, as noted, statistics such as batting average, home runs, or other personalized information about the player that is stored in the device for future reference or updating. An example of such presentation is shown m FIG. 13B. Tne stored information may then conveniently displayed on the LCD 44 for the device holder by the push of scroll button 40 or update button 56, or otherwise transferred through a PCMCIA interface 70 to a computer. Because sports device 12S enables users and owners to trade tne devices 12S among themselves, devices 12S takes on a special value and enhances its worth as it is used. As the sports device 12S acquires data and is updated by use during televised play, the device 12S becomes increasingly more valuable and attractive to acquire. The sports device 12S may be of a design resembling a baseball card and may be traded for other devices 12S. In addition, the sports device 12S may be equipped to retain a permanent serial number or edition number, or other information giving tne nand-held device unique identity or value and thereoy pecommg a valuable collectible. Optionally, the sports device 12S may be connected via an interface such as IR or RF to transfer stored information to another device capable of receiving those results. The sports device 12S may therefore be used in rotisserie opportunities. In addition, the sports device 12S may provide capability for certain permanent characteristic information, such as the batter's name, team, previous teams, and other characteristics, personal data, and additional data that may become permanent based on received statistics and information. Sucn characteristic information may be called to LCD 44 or otherwise transferred to, received by, and displayed on a computer. Sports device 12S may be used for coupon indicating and redemption purposes. During play, other information such as a trivia game or quiz may be received by the sports device where the answer will be revealed later, sucn as during the course of the game, at the end of the game, during half-time, or at any other appropriate time during play. A game may be part of a promotion wherein a user selects the answer and purges the remainder of the stored data, then takes the device to a benefit store or other redemption site during the course of the next week, and has the possibility of receiving some kind of discount or prize based upon the answer selected. Such a game could be part of a "guess today' s attendance" at a professional baseoall game curing seventh inning stretch. Use of sports device 12S in connection with a baseball game is merely illustrative. Other sports m which players have statistics wnich change during play, over a year, or which may include information unique to the player, such as hometown or previous teams, may similarly be downloaded or conveyed by the device. Sports device 12S may also be used in connection with concerts and other special presentations, when televised or appropriately presented. Users are able to acquire useful information about the concert or special presentation, such as the names of performers, set lists, the venue location and history, and related Internet addresses. Persons with hearing impairments may receive real time text of live speeches on their hand-held device auxiliary data transmitted by RF is received on the device. Thus, an alternate version of the sports device 12S may be used to receive information relating to monuments, buildings, cars, animals, etc. during the course of a live or video presentation, wherein the transmission to the device may be received and contains auxiliary data. An alternate version of the sports is a hand-held device that may be termed a "gaming" device. The gaming device, similarly to the sports device, encourages users to interact with video broadcasts of sport events. However, in this embodiment, users viewing a televised live sporting event utilize their gaming device to predict future actions by a selected player or team to amass points in competition with other users. For example, two baseball teams compete in a game featuring live modulation of auxiliary data. A sponsor or various sponsors distribute gaming devices to various participants prior to the start of the game. Users predict each pitch to be thrown for selected batters, pitchers, or teams, using a number code or viewing and selecting from the touch screen display for each pitch. Alternatively or additionally, pitcning results i.e., balls or strikes), hitting results (i.e., strikeouts, walks, hits, home runs, etc.), runs per inning, or other calculable statistics may be selected prior to occurrence. Correctly guessing the occurrence earns points, which accumulate in the memory of the device. Following the game, the device users may submit their hand-held devices either at a collection location or through an Internet connection and submit or upload their scores. The user with the highest point total wins a large prize or discount, with various consultation prizes alternatively available. The predictions may take place for one particular batter, in one particular inning, or for one particular team. Gaming devices may also be used in a similar manner to predict and play other events such as basketball, hockey, and football. Another example of use of the device is as follows: The user watches a trivia game show, such as the television show "Who Wants to a Millionaire?" The user may able to play long, by utilizing their hand-held device. The question is downloaded and received by the hand-held device, either during the broadcast or prior to the broadcast, by the methods described herein. The questions are syncned to tne display device, thus when the display device first presents the questions, the encoded data will trigger the hand-held device to display the question and possible answers. The user chooses the correct answer, or places the answer in order m a timely manner, or must otherwise comply with the rules of trivia game request in a similar manner of the contestants. The user may than receive points or credit for the correct or timely answer based on factors, which may include number of other at home users who answer correctly, or speed of answer. The percentage of at home viewers either nationwide, local, or by other area may be displayed in real or delayed time either on the display device, Internet website, or on tne hand-held device. Thus, users may achieve regional or national rakmgs baseo on their performance. The final results from the various games may be stored at a central database. Users who score high may receive recognition, a prize, or an option to play a future game. Another example of use of the hand-held device is as follows: The user takes there hand-held device and appropriately configures it to receive modulated video from a display device. Upon watching an event, such as the "Grammys", performers appears on the screen and performs their song. The users is notified that an interactive opportunity is available, either through their display device or their hand-held device. This may occurs as the modulated video triggers a graphic rendering unit in a decoder box, thus creating an icon appearing on display device. (Therefore not appearing on the display device of people who do not have such as unit.) The hand-held device provides the user with an opportunity to purchase the song or the album on which it appears . The money for tne purchase can be through online automation or a third-party Internet website, or may be entered or taken from the website. Or, if the user so desires, an order requiring final approval and payment information can be sent to the user' s selected e- mail address. The user can purchase the music m the following manners directly, through a third party' s website such as the affiliate program at "CDNow", or may come directly from the manufacturer. Otherwise, a link for the special purchase can be sent to the user' s regular e-mail address. Bonus or additional rewards may be sent such as a bonus disc with previously unreleased material, live songs or videos, or might include a product discount. Alternatively, the user may have the song sent m appropriate digital format to their e-mail account or the selected song could become available for a period of time at a website for the user to download. Finally, the song could become part of a list that when full to the length of a CD is automatically created and sent to the user. It will be appreciate that this method of purchasing can be used with any manner of products sold (such as jewelry on the "QVC network"), or in ether fields (such as movies) . The hotel card 12H is yet another embodiment of the card with the functions of a sophisticated hotel room key. The hotel card works with a smart card reader lock system, allowing guests of a hotel to enter and exit rooms, such as a guest's hotel room, garage, or pool area. The hotel card can allow similar access by an optional magnetic strip located on the exterior of the enclosure . Upon hotel check-in, guests are given a hotel card to use throughout their stay. Hotels and hotel chains may alternatively issue permanent hotel cards to frequent guests and initiate hotels stay with room access on the user's card at check-m. A child's version of the hotel card can be provided upon check-in, to allow children restricted access to hotel facilities and special promotional benefits available only to children. Once a guest receives the hotel card, the card can be used to enter the guest' s room and other hotel facilities. The guest user can also use the hotel card as a charge card, charging products and services internally, such as dinners at the hotel's internal restaurant, gifts at a gift snop, or snacks from a vending machine. The incurred charges will be recorded on the hotel card, appearing on the user' s bill at check out . Coupons, benefits, or information can be loaded onto the hotel card at check-m and at other desirable times and places, such as the beginning of the each day at the hotel's front desk. Using a smart card writer, the hotel cards can be loaded with opportunities for use or redemption over a limited amount of time. These opportunities or coupons may De discounts for local attractions, cash equivalents such as gift certificates for use at particular local attractions such as a restaurants, information on special pricing, or additional access privileges. The card may also load the guest's hotel preferences, including room type and preferred activities. The hotel rooms may optionally provide reader/writers m the hotel card user's room. Data is written to the smart card as a result of the electronic decoding performed by the docKing station. The docking station can also read the data from the card, and transmit the information to a central computer preferably by a network line or otherwise by a telephone line. Alternatively, the reader/writer can be in the form of a remote control, acting as a cradle when the card is properly inserted. IR sends data back and forth to and from a networked docking station and remote control. The reader/writer reads stored data off of the hotel cards, and displays relevant information on the television the guest's room. Such information may include the total from the purchases using the card, comDined with room costs to generate the hotel bill to date. The guest can also purchase items through use of the hotel card and an appropriately connected docking station for items such as tickets to a local attraction or additional hotel services. An alternative means of reading and writing to the card is through use of a computer and computer interface on the card, as descrioed above . Guests can obtain additional coupons by viewing television programs modulated with auxiliary data. Sucn data may be optically received directly to the card, electronically received by the docking station, or received through a computer interface. The information received Dy the card typically relates to special discounts as well as information aoout area attractions. Television stations or the hotel itself can modulated the television signals to limit the viewers capab_e of receiving the signal. Thus, only visitors having the specialized hotel cards can receive the special discount. The hotel cards can be used as credit cards, and optionally contain a charge limit along with information as to where the card can be used to buy items and then charge them to the hotel room. Thus, businesses outside of the hotel can enact purchase transactions on the hotel carα, which are added to the users bill. The charge limit many optionally varies baseα on guest stay frequency, charge history, or credit history. The hotel or other sponsor may allow the user to collect bonus points by use of the hotel card. Permanent hotel cards store a running total of bonus points, witn optional frequent back ups of the point total to a central computer through properly connected reader/writers. Alternatively, upon each stay the hotel card can De loaded with bonus points earned from previous visits and stored on a central computer. Bonus points can be awarded per stay and per night, or based on other purchases made with the hotel card. Additional bonus points may be earned by visiting local attractions. Bonus points may be redeemed for a gift, discounts, free meals, room upgrades, a free night's stay, or converted to airline frequent flyer miles. Agreements with local attractions provide additional means for user advertising. Indicia of various agreements and sponsorships may be visible on the card's enclosure. Various offers and information on attractions may be encoded on the hotel card. All purchase transactions are logged, and the appropriate charges occur when the guests checks out. The hotel can charge a flat fee or percentage for these promotional activities. Guests have incentives to use their hotel card and visit attractions encouraged by the card. Guests eat at a suggested local restaurant, receiving a discount on the meal, paying by the use cf the hotel card, and receiving bonus points. For example, a local restaurant may have a buy one get one free coupon loaded on to the card , so the guest is more likely to go to that restaurant than a competitor without a coupon. The guest can then visit a major attraction and get bonus points for various suggested activities that they do or items that they buy, for which the purchases can be made through the hotel card. Attractions that wish to honor hotel card promotions should have a reader/writer and a dial-up or network connection to the central computer if a purchase is possible at the attraction. However, accumulating bonus points can be performed by simple write transactions on the card, so that the points are stored on the card and are not immediately transferred to the hotel's computer. At checkout time, the guest's account is cleared out and paid. Guests, if desired, can have an "express check out" such that they do not need to sign a bill, but simply swipe their hotel card across a reader with a connection to the billing center. The hotel card is either returned to the hotel for resetting for future clientele, is disposable, or is made inoperable until the guest's future check-m. Before clearing the card, bonus points and information regarding purchases and uses may be stored in the hotel's computer. On tne next stay, the user's bonus points will again be accessible. Alternatively, a third party or clearinghouse may set up the coupons and distribute the cards. The notel would tnen get a percentage of the overall value of the transactions or a sales commission. Interactive hand-held devices specially configured for conventioneers (or conference attendees) may be termed a "convention" device. Convention devices permit conventioneers to capture information aoout various demonstrators and companies by viewing various booths or viαeo presentations and capturing information or opportunities to the device. Information is captured from the reception of auxiliary data, as is described herein. If the demonstrators so desire, the conventioneers may receive coupons on their convention device for discounts or free gifts from visiting the demonstrators' bootns . The coupons are redeemed by visiting the demonstrator's store or Internet website. Another valuable manner whicn tne devices may be used is to receive auxiliary data at a convention, show, or other any other type of special event, and then offering users opportunities to receive useful information at the special event. For example, a user may watch a video presentation in a convenient location, such as a hotel room, about an upcoming convention. The presentation may show booths, locations or special offers at the convention. As the user sees one of these booths, locations or special offers, the user selectively uses the hand-held device, by pressing its operating button 22 or equivalently initiating control, to cause the device to receive auxiliary data (as descrioed above) which identify these booths, locations or special offers. Then, the user may visit the convention premises, operating the scroll button of the hand-held device to display the booths, locations, map of the premises, or special offers conveniently and helpfully as the user goes about the convention. The convention devices may be presented to the conventioneers with their name and address preloaded, so that the devices may be conveniently read at each convention booth. The convention devices may also provide conventioneer information to the sponsor when used at their store or Internet website. Before or during the convention, conventioneers may watcn television in their hotels rooms or m a common area to learn about the companies tnat will be presenting or have booths at the convention. The conventioneers may selectively receive information or coupons from the demonstrators by optical or electrical methods. Users may receive information such as booth numbers and locations, and as well as opportunities for discounts that may be used during the convention. Another embodiment of the convention device may be referred to as the "museum" device 12M. Museum device 12M allows visitors to trac areas or exhibits at a museum. Embodiments of the αevice may have LEDs 20, to signify receipt of auxiliary data from any of the sources described above. Such a museum device 12M may be used by a schoolteacher to verify that students have visited specific exhibits at a museum or museums that have video demonstrations or otherwise send data through RF. The museum device's 12M LCD 44 may further direct the device's user. The user is provided with instructions on the location of the next exhibit, time left in the museum before closing or before user' s groups departing, redeemable coupons for the museum's gift shop, or other information relevant to the exhibit or museum. Museum device 12M is usable at a series of locations, such that users obtain indicia or information from each location. Museum device 12M may be used m activities such as "scavenger hunt", where users must obtain tne proper information or indicia from each location to win or complete a game or activity. In FIG. 14 a schematic circuit diagram of one form of circuitry that may be used to provide the features and functions of the several embodiments descrioed herein, elements are identified by their conventional numerology conventional characters proximate of the elements. Optional photosensor 30 is seen to be constituted by a photodiode or phototransistor Q2 which provides the signal to amplification and filter circuit consisting of an operational amplifier U1A including a circuit consisting of the components of Cl, R19, R13 and C12 interconnected between the output and the inverting input of operational amplifier U1A, and so providing an amplifier and filter. Thus amplifier and filter signal is provided through R15 to a filter and frequency snap g circuit comprising of an operation amplifier U1B having its feedback circuit the components CIO, Cll and R16. These circuits provide a filtered, frequency-shaped output through a resistor R5 through a circuit consisting of operational amplifier UiC and resistor Rll. Operational amplifier UIC nas an output coupled to a αioαe pair Dll which thus provides a pair of outputs, the upper to a circuit comprising an operational amplifier U1D, providing in effect a Duffer whose output is a data signal delivered through a resistor R20, and tne lower of the diodes Dll providing a signal through a resistor Rl to a further resistor R7 , across which is a capacitor C3. The node between resistors Rl and R7 provides 16kHz signal that is of the horizontal line scan rate or frequency television display optical signals received by photosensor 30 (Q2). The horizontal scan frequency of conventional NTSC color signals is, more precisely, 15.625kHz. (approximately 16kHz, as here described). Similarly, the discriminator circuitry provides at the output of operational amplifier U1D an 8kHz signal representative of the auxiliary data received, as produced by alternate-line luminance modulation of the display. The discriminator circuit thus described provides both the 16kHz and 8kHz (more precisely, 7.8175kHz), which constitutes the actual data, and determines whether the 8kHz data carrying the information (data) content of the received auxiliary data is present by determining whether average signal magnitude of the 16kHz or 8kHz signals is greater, so that if auxiliary data is present, i.e., there is 8kHz modulation energy in the received light signals, they are provided to a microprocessor of tne U2 of the circuit for decoding the information content within the 8kHz signal. Thus, the received composite video signal is amplified and filtered to de-emphasize the 16kHz signal and retrieve the 8kHz signal carrying the data. I.e., wave shaping and frequency shaping filter circuits provided by operational amplifiers U1A & U1B de-emphasize the horizontal retrace frequency and amplify the half-frame rate carrying the data content of interest. The circuits filter the frame rate signal and use it as a reference to compare its relative signal magnitude against the 8 kHz data-carrying signal. If the retrieved 8 kHz signal is of greater magnitude than the conditioned 16 kHz signal, auxiliary data is present and may be utilized by the processor. Microprocessor U2 is preferably of commercially available type Z86E02, and operates according to machine instructions stored m its resident ROM memory. Flowcharts of the functions performed by the machine instructions are set forth the appendix. Although not separately snown microprocessor U8 includes random-access memory (RAM or DRAM) in which decoded data is stored. Thus, microprocessor U2 is to decode and store, or store indication of, the data present m the 8kHz signal, as by illuminating one of more of the LEDs and causing them to remain on as evidence or indication of the data, substantially m accordance with the teachings of Broughton, and to drive displays of the device and/or its LEDs or other signal devices, as well as to provide any audio function, as well as also to energize an aiming LED7 when auxiliary data is present. So also, if desired, a signal may be driven by Ul m response to the presence of the auxiliary data, thus providing an aiming light function indicating, m simple effect, that the hand-held device is receiving composite video signals. For providing illumination of lights 20 or 20a-20d described above m connection with tne various embodiments, shown nere are nine LEDs D9-D18. It will be understood that not all of these LEDs need be used for a specific embodiment of hand-held device 12. That is, tne circuit may be configured so as to drive one, two or three or more of the LEDs as according to the desired function and use of the device. Shown adjacent microprocessor U2 are two diodes D15 and D20 which are used to bypass any noise generated from the microprocessor. The speaker SPK1 is element 34 shown m FIG. 5. A clock crystal XTAL1 provides 8MHz clock signal to microprocessor U2. Capacitors C8 and C9 are part of the clock circuit. Immediately adjacent the clock circuit is a switcn SI to provide the function of button 22 the several embodiments for initiating operation of the device. Switch SI is tied to a power supply circuit comprising power cells a resistor 14, V2 and V3 (each of 1.5v potential), and a resistor 14, and including a switched analog power circuit comprising a transistor Ql and resistors 12 and 13 which enable power to be provided to the array of LEDs D8-D18. Referring to FIG. 14 there is FIG. 15 another version of circuitry invention is shown which may be used to provide still other embodiments of the hand-held devices of the invention. It includes a microprocessor U2 which may of commercially available type Z86X08. It is similarly provided with 8kHz and 16kHz signals (more precisely 15.635kHz and 7.8175kHz) which respectively constitute the horizontal retrace signal and tne data signal at half of that frequency, since the auxiliary data encoded on alternate horizontal lines and so is effectively present at only half the horizontal scan rate, as explained above. These signals are identified as VEILA and VEIL REF that are provided as inputs to microprocessor U2. Therefore, it will be understood that operational amplifier circuits consisting of operational amplifiers U1A, U1B, U1C and U1D provide the same functions of amplification, filtration, frequency shapinσ ano discrimination, as el as Duffer circuits αescriDed m FIG. 14. The microprocessor, clocked by crystal XI at 8MHz, decodes the data provided by the composite video signal, stores it m internal RAM or DRAM and drives an LCD 44 illustrated as circuit component LCD1 which may be, as shown, a 16-character by 2-line display. It may instead be a 12-character by 3-line display, for example, or other format appropriate for the display message to be presented at the surface of the device. Power for the circuit is provided by two cells BT1 and BT2 of 3 volt potentιa_ to a circuit including Q2 to provide not only mam power by auxiliary power, the later being delivered to the microprocessor for maintaining its continued operation, such as for date and time keeping even when the display is not being operated and collectively referred to as Dattery 22. A switch SI is provided for performing the function of power outton 38 (as shown FIG. 6) the several embodiments and, when pressed, enables power to De provided to the LCD1 and other switching functions may be provided by switches S2, which controls scrolling of the LCD 44, and switch S2 may be actuated by scroll button 40 shown m FIG. 10B. Similarly a switch S3 provides a date function that may be actuated by expiration button 42 shown FIG. 10B. These signals control inputs to operational amplifiers U3A and U3D, respectively, and these are provided as inputs to the operational amplifier and also to LCD1. The clear switch will, when operated as described above clause clearing of the date, and the scroll switch enables the user to cause the message across the LCD 44 as that in FIG. 6. Operational amplifiers U3C and U3B provide voltages useful according to the connection illustrated. The circuit embodiments shown are used in conjunction with a method for producing a composite video signal containing video program material and control data, and displaying the signal on a television and decoding such control data for ancillary use, wnerein tne method includes modulating at least one video field within the viewing area of a television in such manner that the modulation is substantially invisible to the television viewer, thereby producing a video subcamer component of the signal (which is as indicated detectable at an 8kHz rate) containing the data; and detecting the component to reproduce the data for the ancillary use. Although luminance modulation is particularly useful for that purpose when using hand-held devices in accordance witn the invention, c.nrommance modulation may instead De employed as according to Broughton. Furthermore, the improvements in modulation described in Ciardullo may likewise be used. Various alternative modulation (and corresponding modulation) schemes may be employed as alternatives, including (but not limited to) amplitude shift keying (ASK), frequency shift keying (FSK) modified frequency shift keying (MFSK) , and phase shift keying (PSK). And although the substantially 8kHz data-carrying submodulation is at half the NTSC horizontal scan rate, other submodulation techniques may be used at other multiples or submultipies or other periodic rates which are other functions of the horizontal scan (retrace) rate . FIG. 16 is a block diagram of circuitry of yet another possible embodiment of the interactive hand-held devices, designated 12F, which shows discriminator and microprocessor circuits 50 which are in accordance with FIGS. 14 or 15, and receiving composite video signals by photosensor 30 so as to decode the auxiliary data and provide either light signals as described aoove, or, preferably, to drive LCD 44 according to the foregoing description. Thus, it includes an update or initiating button 22, as according to the sports device 12S. In addition, an FM receiver 62 and associated antenna 64 may be provided as a surface-mount module added to the printed circuit board of tne device. FM receiver 62 and associated antenna 64 may be of commerciall y available design, suitable for being powered by Dattery 22 or cells (not snown) provided m accordance with the foregoing description of various embodiments. Control button 66 may optionally initiate operation of FM receiver 52 so that it sends FM-demodulated signals to the discriminator and microprocessor circuits 60 that may be configured to respond accordingly either to photosensor 30 or to FM receiver 62 according to whether update button 56 is pressed. The FM receiver 62 alternatively be any type of RF antenna tnat is of the size and accordance with tne invention, sucn that the discrimination may take place on a decoder, and the results are sent to the nand-held device 12 via RF. Hand-held device 12F may be sports device operating otherwise according to version 12S described in relation to FIG. 13, but the addition of FM receiver 62 gives the new device the capability of being used m sports stadiums and other performance venues where video signals are not available. Thus, the device 12 may receive eitner optical signals or electrical signals. In the case of a sports device according to FIG. 13, the user may as described above receive statistics about a player depicted on the device, or aoout a player at bat. According to a preferred method of using device 12F, the same auxiliary information as would be transmitted via a television broadcast for being received on a display device 10, there to be displayed as composite video signals, is in addition transmitted by low-power FM signals the FM broadcast bano of 88-108 MHz. For this purpose, FM receiver 62 may be pretuned to an appropriate frequency for such low-power signals. The FM signals may include batter statistics, for example, as batters come to bat, so that holders of the new devices 12F may update their devices as their preferred batters come to bat. Hand-held devices 12 may have use in various sports events, entertainment presentation, conventions, museums, tours, and guided events at whicn holders of devices might not conveniently use them while in the presence of a television display carrying auxiliary data, but where the location in whicn the devices will oe used will permit low-power FM or other RF signals. Other commercially significant usage of the devices of FIG. 14 can be made, similar to the methods of using the previously described versions. Similarly, devices of the invention may be adapted to receive AM signals, or auxiliary light signals such as IR (infrared) light signals, different from the composite video signals. Similarly, hand-held devices 12 of the invention, whether or not sized as "cards", PDAs, or cell phones or other conveniently hand-held size, and whether m the form of racing devices, may simulate other objects, vehicles, personalities, or devices for house-hold, personal or Dusmess use, so as to provide a verisimilitude or facsimile representation of such devices or usage, so that the hand-held device suggests to the user the manner of its use, or conveys to the users special feeling, sense, identity or association with a field, activity, sport, entertainment or other use of the device it represents. In games, for example, in whicn some or all of the information content useful in the game may be provided by auxiliary data, hand-held devices of the invention configured to provide a verisimilitude or facsimile representation of such devices or usage may give players of the game enhanced sense of play, participation or gaming identity. The foregoing are merely illustrative of the many possibilities . When used a system for deriving benefit from encoded data including means for producing video signals modulated with auxiliary data, such as by providing commercially sponsored television programming including auxiliary data, new hand-held devices of the invention nave special impact for television response, advertising and promotions, as the new system and devices are useful in providing, among others, the following commercially advantageous results when they are distributed to viewers and used by viewers to receive auxiliary data transmitted with normal programming content, which may include advertising, promotions and other sponsored transmission. A method for card redemption is described the context of an optically loaded card, however, such a method could also be employed with other cards that nave coupor redemption requirements. The components of ar electronic couponing card wnich support the method for card and value redemption include: 1.) LCD or other human readable method to display data . 2.) On board computation to sequence the logic defined below. 3.) A method to load "electronic coupon" information onto a card. 4.) Buttons or other method (such as a touch screen) to sequence through the coupons loaded on tne card. 5.) Button or other method (such as a touch screen) to put the card in "redeem" mode. 6.) Laser detection hardware described below. Presently, most POS systems use a computerized cash register tied to inventory management software and bar code scanning hardware. One embodiment of a method of using an electronic coupon card and existing hardware and software located at a POS for electronic coupon redemption is described in the following steps: 1.) Coupon data is encoded onto a video signal, e.g. television signal. The encoded data would also contain additional text describing the coupon along with a numeric code to be entered at the POS. 2.) The user points the multi-use card at the television screen wnen the television signal containing the coupon data is airing. The electronic coupon data is then captured by the card by optically receiving the data that is presented on the display. The coupon data could also be captured with methods other than optical detection, including but not limited to radio frequency (RF) or hard-wired electronic data transfer . 3.) After capturing the electronic coupon data, the user can tnen view coupon information sucn as requirements, valid dates, valid POS locations, etc. on the LCD of tne card. (Other numeric codes described in the following steps that are used for identification and security purposes are not available for viewing by the user at this time; . 4. ) Wnen the user desires to redeem the electronic coupon, the card is transported to a POS and the user buys the desired item or otherwise follows the requirements of the coupon offer. 5.) At the check out, the cashier takes the card and locates the correct coupon using the scrolling function (usually a button) of the card, in concert with viewing the data on the LCD screen. 6.) The casnier then presses the required "redeem" button on tne card. The cashier then has approximately one minute to complete steps 7 and 8 below. Requiring this button to be pressed reduces the likelihood that a coupon will De accidentally redeemed through bright ambient light. 7.) When the correct coupon s located, the card is held with the LCD screen facing the casnier and the back of the card facing the bar code scanner located near the cashier. The bar code scanner is the same scanner that is used for purchases and conventional paper coupon redemption. a . ) When tne scanning laser light is αetected by the card, tne card Deeps and the numeric code described m step #1 is displayed on the LCD screen. In addition, another code that represents the serial number of the card is also displayed. The second number displayed could also be a special code generated as a combination of the downloaded numeric value (step #1) and a hidden internal (to the card) serial number. The second number can be generated by various standard encryption metnods and could be used to increase tne security of the transaction Because it would uniquely identify the card and transaction but would not be easily duplicated. 9.) The casnier then has 30 seconds to enter either the numeric code only or both the numeric code and card serial number (for greater security). After 30 seconds, the card automatically erases the coupon. The coupon may also be erased quickly oy a press of the "redeem" or "scroll" keys during tne 30 second period. (The scroll key is used to allow multiple coupons to be located and redeemed efficiently as described below) . 10.) If additional coupons are to be redeemed at the same time, the above steps are completed for the first coupon. Additional coupons are redeemed with the cashier repeating steps 5 through 9 above . In an alternative embodiment, steps 8, 9, and 10 are replaced with the following steps : 8'.) When the scanning laser light is detected by the card, the card beeps and displays a numeric code, or alternatively an alphanumeric message, on the LCD screen. In addition, another code that represents the serial number of the card is also displayed. The second number displayed could also be a special code generated as a combination of the downloaded numeric value (step #1) and a hidden internal (to the card^ serial number. The second number can be generated by various standard encryption methods and could be used to increase the security of the transaction because it would uniquely identify the card and transaction but would not be easily duplicated. 9' . ) The cashier, upon viewing the number code or alphanumeric message, can determine whether or not the triggered card is the card that was preselected to win a prize or to receive a special value or discount. If the card alerts the casnier that a prize has been won, tne cashier may optionally enter the second number (step #8b) into a database to verify that the card has not been tampered or altered. The prize may also be erased quickly by a press of the "redeem" or "scroll" keys during the 30 second period. (The scroll key is used to allow multiple prizes to be located and redeemed efficiently as described below) . The following describes how detection of a laser scan across the card can be accomplished: Almost all bar code scanning devices use a red laser of either the helium neon (HeNe) or diode types. The scanners deliver an extremely bright light in the 832.8 nanometer (nm) wavelength for the HeNe or 640nm wavelength for the diode lasers. The wavelength spread for a laser is extremely small, which allows for narrow optical filters so that non-laser ambient light can De filtered out. A simple electronic/optical circuit is shown m Fig. 17 and can be used to detect the signal. As shown in Fig. 17, electronic/optical circuit 100 includes optical filters 120a and 120b, load resistor 140, microprocessor trigger 160, and phototransistor 180. Optical filters 120a and 120b are used to prevent the electronics of the card from being triggered by ambient light, e.g. bright sunlight. Optical filter 120a is a neutral density type to reduce tne intensity of light and optical filter 120o is a red bandpass type. A photodetector is required to detect the laser light. This detector can be phototransistor 180 since only an ON/OFF signal is required. Phototransistor 180 has a small resistive load on it, as represented by load resistor 140 so that phototransistor 180 is less sensitive to light. Load resistor 140 therefore reduces unwanted triggering. The output of electronic/optical circuit 100 is fed into a microprocessor on the card where the output then becomes the trigger that causes the beep, etc. as described m the above steps. In view of the foregoing description of the present invention and practical embodiments it will be seen that the several objects of the invention are achieved and other advantages are attained.
