Description:
RELATED APPLICATIONS 
     This application claims priority to United States Provisional Patent Application Ser. No. 60/148,557, filed Aug. 12, 1999. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to the fields of credit and debit cards and computer storage mediums. 
     2. Relevant Technology 
     Magnetic strip cards are well known and in wide use for transactions relating to credit and debit accounts. A magnetic strip card is embodied as a plastic card having a magnetic strip comprising a magnetically sensitive material. The magnetic strip is oriented through conventional magnetic technology to store a user&#39;s account number corresponding to a user&#39;s credit or debit account. During read operations, the magnetic strip card is “swiped” through a reader having a magnetic head that senses the magnetic polarities encoded on the magnetic strip to thereby derive the account number. A merchant may then debit or credit the appropriate account based on the account number. The simple and efficient operation of the magnetic strip cards have made them extremely popular and an integrated part of modern day commerce. 
     Another popular computer readable storage medium is the optical disk which can store large volumes of high density information. The optical disk operates by storing information on a disk in the form of lands and pits. Data stored on the optical disk is typically configured in a single track that spirals from the center of the disk to the disk&#39;s circumference. An optical disk drive generates a tightly focused laser beam to strike the lands and pits on the surface of the disk. Light that strikes a pit is scattered and light that strikes a land is reflected directly back at a detector. By reading the lands and pits, the detector generates electrical voltages which are matched against a timing circuit to generate a binary stream. The binary stream is in turn read by a computer. The optical disk may be embodied in various forms including erasable optical disks, WORMS (write once, read many), and DVD. 
     A convenient aspect of the magnetic strip card and the optical disk is that both are portable hand-held computer readable mediums that may be carried to electronic read devices at various locations. Read devices are only able to read corresponding optical disks or magnetic strip cards for which they are specifically designed. It is common practice to carry magnetic strip cards for everyday commerce and personal identification. Thus, consumers are well accustomed to their use. 
     In the ever growing world of electronic commerce there are advanced advertising, marketing, and transaction applications which sponsors may wish to incorporate into a transaction card. Such applications require large storage capacities and would clearly exceed the storage of a magnetic strip card. Optical disks are optimal at providing high capacity storage for multimedia data and other high end applications. Optical disks may further be shaped and sized to allow them to be carried in a purse or wallet. Thus, it would be an advancement in the art of commerce and personal identification to have a computer readable transaction card combining the features of the magnetic strip card with the comparable extensive memory capability of an optical disk. Such a device is disclosed and claimed herein. 
     SUMMARY OF THE INVENTION 
     The interactive transaction card of the present invention comprises an optical disk which is readable by a computer&#39;s CD ROM drive. The transaction card further has a magnetic strip disposed on a surface of the optical disk. The magnetic strip has an identification code, such as an account number, which in today&#39;s business transactions identifies a user&#39;s credit or debit account. The proposed optical disk is configured to be insertable into a magnetic card reader. The magnetic card reader, as always, reads the magnetic polarities of the magnetic strip to derive the expected identification code as required to complete a transaction. To enable e-commerce via the computer, the identification code may also be stored on the optical disk to allow the CD ROM drive to read and transport code. 
     The optical disk may contain multimedia modules including various audio, still or motion pictures, graphics, and video files. Some of the modules are interactive to the user and some are interactive with a computer. This allows a user the convenience of having a conventional credit and debit card with the added benefits of multimedia presentations and interactivity. Thus, a user may receive promotional and instructional material on the interactive transaction card. The optical disk may further include a module programmed to provide an automatic Internet connection where commerce can be simplified through the availability of the identification module. A card&#39;s Internet browser may be directed to display the web site of the transaction card issuer, associated merchant, or other advertiser. The user may then transact on this web site, other sites, or receive additional promotional or instructional information. 
     The interactive transaction card combines the advantages of two computer mediums to provide a card with (1) magnetic strip technology and (2) high capacity storage for additional commercial features. These and other objects, features, and advantages of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The presently preferred embodiments of the present invention will be best understood by reference to the FIGS. 1-6 wherein like parts are designated by like numerals throughout. It will be readily understood that the components of the present invention, as generally described and illustrated in the Figures herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the apparatus, system, and method of the present invention, as represented in FIGS. 1 through 6 is not intended to limit the scope of the invention, as claimed, but is merely representative of presently preferred embodiments of the invention. 
     Referring to FIG. 1, the transaction card of the present invention is shown and generally designated  10 . The transaction card  10  comprises an optical disk  12  such as a compact disk (CD), WORM, erasable optical disk, or a DVD. The optical disk  12  comprises a sprocket hole  14  to accommodate engagement with a CD ROM drive to allow rotation of the optical disk  12 . In one embodiment, the optical disk  12  may be configured with a read side (not shown in FIG. 1) which has a reflective layer for reading of the optical disk  12  and a non-read side or visual display side  16  upon which a label may be attached. The optical disk  12  is configured as is well known in the art to be suitable for engagement with a drive. In any of the suitably known configurations the optical disk&#39;s  12  shape inherently positions the optical disk  12  properly in a drive. 
     Standard diameters for optical disks are 120 and 80 mm. Optical disks  12  which are approximately 80 mm in diameter are one presently preferred embodiment as they are accepted in most CD ROM drives. Furthermore, the 80 mm diameter length is a suitable length for a transaction card which usually is expected to be convenient to carry in the palm of user&#39;s hand as well as in a wallet or purse. 
     In the embodiment shown in FIG. 1, the optical disk  12  has a hybrid shape in that it has opposing ends  18  which are radial and opposing width ends  20  which are chords in configuration. One of skill in the art will appreciate that the present invention is not limited to the shape shown in FIG.  1 . The opposing ends  18  have diameters, such as 80 mm, which allows the optical disk  12  to nest in a CD ROM drive. The width ends  20  provide a shape which more closely approximates a conventional magnetic transaction card and facilitates insertion of the card into magnetic read devices and into a purse or wallet. The width of the optical disk  12 , defined as the distance between the two width ends  20  approximates the width of a conventional transaction card. In one embodiment, this width may be 55 mm. Thus embodied, the optical disk  12  is of a shape and size for insertion in CD ROM drives, magnetic read devices, and purses or wallets. 
     The optical disk  12  has information stored thereon which is referenced herein as modules. Modules may include any type of computer instruction or computer executable code located within a memory device and/or transmitted as electronic signals over a system bus or network. Some of these modules may interact with other modules stored on the interactive transaction card  10 . An identified module may, for instance, comprise one or more physical or logical blocks of computer instructions, which may be organized as an object, procedure, function, or the like. The modules may further include operational data, extensive personal data for identification or qualification, and multimedia applications such as text, audio, video and so forth. 
     In one embodiment, the transaction card  10  further comprises a magnetic strip  22  which is disposed on one surface of the optical disk  10 . In one embodiment, the magnetic strip  22  is disposed on the non-read side  16  or visual display side of the optical disk  12 . The non-read side  16  may also be referenced as an identifying, logo, or graphics side of the transaction card  10 . This is in contrast to magnetic strip cards which typically place the magnetic strip on the surface opposite the identifying or advertising display surface. Alternatively, the magnetic strip  22  may be disposed on the read side but located on the optical disk  12  so as not to interfere with a drive&#39;s reading of the optical disk  12 . The magnetic strip  22  may be configured in a generally linear and rectangular shape as is well known in the art. In one embodiment, the magnetic strip  22  is disposed parallel to the length of the optical disk  12  and has a width of about, but not limited to, {fraction (5/16)} inches. 
     The magnetic strip  22  has magnetically encoded thereon an identification code  24 . The identification code may comprise numbers which represent a credit or debit account or other designation as is standard in the industry. The magnetic strip  22  may be read by a magnetic reader to allow the transaction card  10  to function as a conventional credit or debit card or personal identification card. 
     As with conventional magnetic strip cards, the transaction card  10  may further be embodied with a signature box  26  as is usually embodied on a traditional credit card. The signature box  26  may be disposed parallel to the magnetic strip  22  on the read side. An account number may also be printed on the read or non-read side  16  of the transaction card  10  as with conventional magnetic strip cards. This would allow manual reading or manual entry of an account number by a merchant for crediting or debiting of the account. 
     Referring to FIG. 2, an alternative embodiment of the transaction card  10  is shown. The read side  28  is shown and is configured with a read area  30  and a non-read area  32 . The read area  30  enables reading by an optical device. The non-read area  32  may be an etched area and provides a user with a signature signing area such as a signature box  26 . The signature box  26  may be located in alternative positions or eliminated entirely. 
     The optical disk  12  portion of the transaction card  10  is constructed with a thickness and shape which enables it to function as a traditional credit card in a standard magnetic card reader through the identifying feature of the attached magnetic strip  22 . The thickness of the optical disk is manufactured to be suitable for use with conventional CD ROM drives and conventional magnetic strip readers. 
     The optical disk  12  may be embodied in various shapes for aesthetic features so long as it remains compatible for use with CD ROM drives. With reference to FIGS. 3-5 only a few, possible alternative shapes for the optical disk  12  of the present invention are shown. 
     Combining the traditional magnetic strip and optical disk technologies together into one transaction card  10  presents new opportunities for electronic commerce and extensive personal identification, and promotional and advertising venues. An issuer of the transaction card  10  may code the optical disk  12  with any number of information messages some of which are interactive with the user for play on a computer. An optical disk  12 , such as a CD ROM, can presently store thousands of times the amount of information that a magnetic strip can store. This vast amount of storage allows the optical disk  12  portion of the transaction card  10  to contain extensive personal identification material as well as media features including advertising and educational messages through pictures, audio, and film clips. The transaction card may also include a digitized photograph of the user. In this manner, a user may receive advertising promotional material, commercials, special offers, as well as the issuer&#39;s message or a message paid for by one or more venders. The invention may therefore serve to replace printed catalogs with interactive catalogs. At the same time, the magnetic strip  22  portion provides an identification of a user&#39;s account or other personal information relating to the user for operation as a credit, debit, or personal qualifying card. 
     Referring to FIG. 6, a block diagram of modules  200  which may be stored on the optical disk  12  is shown. Modules  200  stored on the optical disk  12  may be allocated to one or more advertisers or merchants. Advertisers or merchants may be charged different rates depending on the positions of their respective modules  200  stored on the optical disk  12 . For example, a module  200  which is loaded first is a more prominent position as it is more likely to be viewed or executed. The more prominent positions may be charged a higher rate than other positions on the optical disk  12 . Advertisers or merchants may further be charged different rates based on the order that their websites are displayed when their transaction card  10  executes a connection to the Internet. In one embodiment, the card user will be able to control the order influence of these positions at any time. For example, a user would not be required to view more prominently placed advertisements prior to arriving at a desired message. 
     The modules  200  may include multimedia modules  202  including various audio, pictures, graphics, and video files. An auto-load module  204  may further be stored on the optical disk  12 . The auto-load module  204  enables autoloading of one or more modules stored on the optical disk  12 . The auto-load module  204  may also load a connection to the Internet in the background when the optical disk  12  is inserted into a CD ROM drive. 
     In addition to providing multimedia to a user, the optical disk  12  may further include an Internet link module  206  configured to provide a link to the Internet. The Internet link module  206  may be enabled automatically by the auto-load module  204  to load the Internet in the background while the transaction card  10  presents a multimedia application. Thus, upon insertion of the optical disk  12  into the CD ROM drive, a connection is established to the Internet. Ideally, a computer&#39;s browser is then directed to display the web site of the transaction card&#39;s  10  issuer, associated merchant, or other advertiser. 
     The Internet link module  206  may also be configured to engage the browser operations on a computer to drive an Internet presentation. The Internet link module  206  may be configured to enable its own browser and establish its own connection to the Internet independent of other browser software on a computer. The Internet link module  206  could thus function as its own “portal” to the Internet. In this manner, an Internet connection may be enabled if the appropriate computer equipment exists. The computer may be instructed by the Internet link module  206  to log onto a designated server which would provide the Internet connection. This Internet connection may be performed as an advertising or instructional service with little or no additional cost to the user. The Internet link module  206  may further be configured to limit the web sites available for viewing. For example, a user may only be able to view the web sites for sponsors associated with the transaction card  10 . 
     The Internet link module  206  may include a message module  208  configured to send a message to a web site to identify the user and the transaction card  10 . The message may include the user&#39;s identification or account number or other confidential information to accomplish an electronic transaction. The message module  208  may be configured to transmit the message in an encrypted format. 
     One or more of the modules  200  may be stored in an encrypted format on the optical disk  12 . The modules  200  may also include an encryption module  212  for encrypting data such as one or more modules stored on the optical disk  12 . A module  200  may therefore be transmitted in an encrypted format to ensure confidentiality. Thus, confidential or otherwise personal information on the optical disk  12  may be protected using standard encryption technology. 
     An identification module  210  may also be stored on the optical disk  12 . The identification module  210  may contain information specific to a user. In one embodiment, the identification module  210  may contain the identification code  24 . The identification module  210  may be read by a CD ROM drive to retrieve the identification code  24  or other user information. The high storage capacity of the optical disk  12 , allows the identification module  210  to contain thousands of times more extensive user information than the magnetic strip. For example, the identification module  210  may contain a user&#39;s complete credit history, medical history, transaction history, bank or financial account history, driving history and so forth. Thus, the information stored on the identification module  210  need not be limited to credit or debit concerns exclusively. 
     The identification module  210  may further contain multiple identification codes  24  specific to various entities, sponsors, etc. Thus, the memory capacity of the optical disk  12  allows for numerous interactive uses. The card  10  may replace several conventional transaction cards by incorporating all of their features and accounts into the card  10  by virtue of the memory capacity of the optical disk  12 . Thus, the need for carrying multiple credit cards is eliminated. For security, identification codes  24  may be encrypted and would only be accessed by related and authorized entities with proper encryption. Thus, an entity will only be able to access an identification code  24  specific to their organization and will be unable to access non-related identification codes  24 . 
     The memory capacity of the optical disk  12  further allows for redundant storage of one or more identification codes  24 . If a portion of the optical disk  12  is damaged, the redundant storage of identification codes  24  increases the likelihood of being able to read the identification code  24  from an undamaged portion of the optical disk  12 . 
     After retrieving the user information, such as an identification code  24 , from the optical disk  12 , the message module  208  transmits the user information on line through the Internet for electronic commerce. The user information may be encrypted by the encryption module  212  to retain confidentiality. Alternatively, the user information may be originally stored in an encrypted format. Programming may be made available on the Internet to websites for downloading code to allow the site to recognize and use the identification code  24  on the card  10 . Thus, the encrypted user information may only be viewed by websites having suitable decryption. In this manner, the sensitive nature of the user information may be preserved. 
     Websites may be enabled to operated in conjunction with the transaction card  10 . A website may contain a multimedia module which is downloaded to a user&#39;s computer for operating the multimedia module  202 . The website may contain further programming which is downloaded to a user&#39;s computer to increase the interactivity of the card  10 , the user&#39;s computer, and the website. As previously stated, the website may further contain an encryption module for decrypting sensitive information received from the transaction card  10 . By placing these and other modules on the website, additional space is available on the transaction card  10  for sponsors. 
     The website may further contain modules for transaction and banking to enable e-commerce and interact with the transaction card  10 . Thus, the website and the card  10  form a part of an e-commerce system. A user may log onto a website and, through application of the card  10  to identify a user&#39;s account and supplying a PIN number, view a balance in a user&#39;s account. The card  10  may incorporate a PIN for security for viewing an account balance and for finalizing a purchase. The user may also view account information relating to payment due dates, minimum payment amounts, overdue interest and so forth. Through additional web programming, payments due could be made with the interactive card. A user may then perform on-line shopping, once again by application of the card  10  to identify the user&#39;s account. 
     The card  10  may also contain programming reflecting a monetary amount, such as a prepaid amount. The monetary amount may be stored in either the magnetic strip  22  or on the optical disk  12 . The monetary amount may be used towards purchases at store locations or on-line on the Internet. The monetary amount may be limited to purchases with one or more sponsors, or may be limited to purchases of a certain nature, i.e. sport venues. In this manner, the card  10  may function as a gift certificate as well as a credit card. 
     In another embodiment, the transaction card  10  may not have a magnetic strip  22 . Thus, the transaction card  10  could not function as a conventional magnetic strip card. In such an embodiment, the identification code  24  may only be stored in the identification module  210  on the optical disk  12 . 
     By way of example of operation, a user may receive the transaction card  10  upon purchasing a product. The user may insert the transaction card  10  into a CD ROM drive to enable a multimedia module  202  for instructions on product use. The user may also enable the Internet link module  206  to register the product on line utilizing a code contained in the programming, or other supplied product material, through the Internet. The user may further use the identification code  24  on the transaction card  10  as needed for warranty or other product use as well as crediting or debiting of an account. 
     The present invention provides a convenient portable card enabling increased opportunities for multimedia applications. A user may use the interactive transaction card for education, reviewing advertisements, Internet use, electronic commerce, personal or demographic information, as well as conventional debit and credit transactions. The transaction card  10  is designed to be interactive with the user and with a host over the Internet. The present invention incorporates familiar computer mediums which have been accepted in commerce. 
     The present invention may be embodied in other specific forms without departing from its scope or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
