## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This utility application claims the benefit under 35 U.S.C. §119(e) of Provisional Application Ser. No. 60/590,548 filed on Jul. 23, 2004 entitled SELF-CHECK SYSTEM AND METHOD FOR PROTECTING DIGITAL MEDIA and whose entire disclosure is incorporated by reference herein.


BACKGROUND OF THE INVENTION
Field of Invention
This invention relates to collection management and theft deterrent systems. This invention improves the mechanism in which products are secured within a borrowing facility. More specifically, the invention removes the requirement for a clerk to remove security devices on the product so that the product can be sold, rented or borrowed.
Currently, there are many known security mechanisms which help deter the theft of a product from a borrowing facility. Security tags play a major role in inventory control to help prevent theft or “shrinkage” of inventory. Basic security tags such as disclosed in U.S. Pat. No. 3,696,379 (Minasy) discloses a passive tag that is energized by an electromagnetic field when the tag is brought into the range of a set of antennas. The antennas are customarily placed at the exits of the borrowing facility. Once the activated tag is brought into the field of antennas, the antennas then initiate an event, such as flashing lights, sounding an alarm, or logging an item-specific identifier. Conventionally, the tags are placed onto the media's packaging. This technology has limited use in digital media since the packaging has little or no value. The media itself can be taken without sounding any alarms. EAS (electronic article surveillance) tags are a type of tag that has two statuses, on or off. A normally functioning EAS tag is always on. Thus, when the tag is brought within range of an antenna, the tag is activated by the antenna and returns a signal to the antenna. There are only two ways to turn off the tag: either physically destroy the tag (EMP (electromagnetic pulse), magnetic energy, etc.) or block the tag with a detuning material so it cannot be activated.
Two products are known in the industry, which help protect facilities against this problem. They are generically referred to as “security boxes.” One version is sold under the name of SAFERTM (by Checkpoint Systems, Inc. of Thorofare, N.J.) and one is sold under the name of “Clear Vu” (by Clear-Vu of Westbury, N.Y.). These security boxes essentially lock an item (e.g., digital media such as CD (compact disc) ROM (read-only memory), DVD (digital video disc), etc.) in a box and require an unlocking mechanism to remove the item from the box. When this technology is combined with an internal security tag, an effective theft deterrent system is established. The box cannot be opened to remove the media, and the box will sound an alarm if it is brought into range of the antennas. Typically, this technology is employed with EAS tags, where the tagged security box is passed around the antennas so the media can be given to the patron. Any size item can be stored inside the box, but typically most items occupy a considerable portion of the box's internal volume.
The combined security tag and security boxes have several known shortcomings. The borrowing facility has difficulty taking inventory of the item in the security box since the contents cannot easily be visually inspected to determine what the box contains. Additionally, this system still requires an employee to manually check out the media since the employee needs to log which media is being rented or sold, and the employee must pass the media around the antennas or place a detuning device to the tag. This results in longer lines in borrowing facilities, and more employees working at check-out registers. If the security tag is located on the packaging of the product case, the clerk must remove the security box and pass the loaned material around the antenna or place a detuning material over the tag.
One other problem that patrons who rent digital media may encounter is the accrual of late fees even though they are certain that they returned the digital media to the borrowed facility well before the return time deadline. Some of this can be attributed to the employees actually taking the returned digital media and then viewing it themselves and then entering the return time of the digital media after the deadline. Without any way to verify this, the patron has no recourse but to pay the late fee.
Thus there is a long felt need to allow for an automated check-out/in system that would track which media is being rented, allow for secure interrogation of the item and provide for verified return time of rented digital media by patrons.

DETAILED DESCRIPTION OF THE INVENTION
The invention of the present invention is envisioned to be used on any device that uses an existing lockable casing to secure the product. Non-limiting examples may include keys, PC cards, video games, or jewelry, etc. The majority of this disclosure concerns with applying this inventive concept towards securing DVD or CD media, but it is understood and contemplated that this technology could be employed to other technologies such as the above mentioned keys or video games.
The system 20 of the present invention is shown in FIG. 1 and basically comprises a check-out station 22, a computer 24, database 26 and pedestals 28. The check-out station 22 provides for an automated method whereby a patron presents the digital media and performs a self-check-in without the need for any store employee assistance. The check-out station 22 communicates with the computer 24/database 26 for storing status information about the digital media 2 to be removed; the check-out station 22 also comprises an unlocker 30 that unlocks the digital media container. If a valid rental (or purchase) occurs, the computer 24 controls the “unlocking” of the digital media container as well as the de-activation of an alarm 33 that is triggered by detection at the pedestals 28. The pedestals 28 comprise antennas and a tag reader (e.g., an RFID reader). As will be discussed in detail later, the unlocker 30 may comprise a power supply 44, a switch 46 and an unlocker device 48 (e.g., a magnet or electromagnet, etc.) although this is by way of example only and many other unlocker 30 configurations fall within the broadest scope of this invention.
In order to understand the system 20 operation, it is necessary to discuss how the particular digital media, e.g., CD ROMs (hereinafter “CDs”) or DVDs, are provided to the patron for rental or sale for use with the system 20.
As shown in FIGS. 2 and 3, the digital media 2, CD or DVD, comprises an ID tag 32, most preferably, an RFID (radio frequency identification) tag. RFID tags are disclosed in, by way of example only, U.S. Pat. No. 6,025,780 (Bowers) and U.S. Pat. No. 6,195,006 (Bowers et al.), both of which are incorporated by reference herein, and are designed to give detailed information about the product when the tag 32 is activated. To secure RFID tags directly to digital media 2, an annular tag construction is preferred since it can be secured to the clear plastic hub 2A that surrounds the hole of the CD/DVD and which is not read by the CD/DVD player. By way of example only, one such annular RFID tag 32 is sold under the mark CIRCULATION CIRCUIT® by the Assignee of the present application, namely, Checkpoint Systems, Inc. This RFID tag, hereinafter referred to as “RFID content tag” 32, stores details about the particular digital media in its RFID integrated circuit. For example, the name of the media (e.g., title, song names, movie name, author, singer, production company) and/or a serial number, or any other information that is pertinent to that digital media is stored in the RFID content tag 32. Such information can be used for inventory, collection management and store operation efficiency statistics, or any other useful task information. In this manner, the identity of the digital media 2 can be obtained simply by having an RFID reader, tuned to the frequenc(ies) of the RFID content tag 32, activate the RFID content tag 32 to elicit that information. Moreover, if the digital media 2 is stored in an opaque container (e.g., a security box, as will be discussed in detail next), there is no need to remove the digital media 2 to identify what it is.
As mentioned earlier to deter theft, most digital media 2 is now placed within a security box that cannot be opened unless a proper rental or purchase is performed. By way of example only, two types of security boxes are shown for use in the system 20 but it should be understood that the system 20 is not limited in any way to only these two types of security boxes.
FIG. 2 depicts an exemplary security box 8A that opens and closes like a book and which includes a releasable locking mechanism 9. This type of security box 8A is usually opaque and therefore the patron has to rely on any printing or labels on the outside of the security box 8A to determine the content of the security box 8A unless and until the patron can place the security box 8A near an RFID reader that will activate the RFID content tag 32 to reveal the contents. In order for a patron to open the security box 8A, he/she must perform a valid rental/purchase transaction, in which case the patron then places the security box 8A into the unlocker 30 that opens a releasable locking mechanism 9 since a valid rental or purchase has occurred.
For example, as shown most clearly in FIGS. 4A-4B, the releasable locking mechanism 9 may comprise a pair of sleeves 9A/9B, a pair of locking tongues 9C/9D and a locking bar 9E; the locking bar comprises a pair of notches 9F that correspond to a pair of protrusions 9G in the tongues 9C/9D. With the security box 8A closed, and the locking bar 9E slid downward through the sleeves 9A/9B, the protrusions 9G are biased into the notches 9F, thereby locking the security box 8A closed. Application of the requisite magnetic field from an unlocker device 48 (e.g., using a magnet 10, see FIG. 4B) of the unlocker 30, pulls the ferromagnetic tongues 9C/9D toward the unlocker device 48, thereby disengaging from the notches 9F and allowing the locking bar 9E to be slid upward in the direction of arrow 11. The patron removes the bar 9E, places it into a retrieval bin 9H (see FIG. 1) and then proceeds with the rented/purchased digital media 2 to the exit.
As used with the system 20 of the present invention, the security box 8A itself comprises a security tag 34 (FIG. 9). The security tag 34 can be either an EAS tag or an RFID tag. These tags can operate in the frequency ranges set forth below:











EAS Operation
RFID Operation


















Low Frequency (LF)
 5 kHz-12 kHz
Low Frequency (LF)
100 kHz-400 kHz




High Frequency (HF)
 2 MHz-14 MHz


Acousto-Magnetic (AM)
50 kHz-70 kHz
Ultrahigh Frequency (UHF)
860 MHz-930 MHz


Radio Frequency (RF)
 2 MHz-14 MHz
Microwave Frequency
2.3 GHz-2.6 GHz









The security tag 34 provides theft deterrent in that if the security box 8A is attempted to be removed from the store without a valid rental or purchase, not only will the thief be unable to open the security box 8A to remove the digital media 2, but once he/she arrives at the pedestals 28, they will activate the alarm 33 upon detecting the presence of the EAS or RFID security tag 34. In contrast, if the valid rental or purchase has occurred, the pedestals 28 will not activate the alarm 33 as the patron passes through them with the security box 8A. By way of example only, the security tag 34 may be implemented using the security tag disclosed in U.S. Pat. No. 5,081,446 (Gill, et al.) whose entire disclosure is incorporated by reference herein and which is owned by the same Assignee, namely, Checkpoint Systems, Inc., as the present application.

FIGS. 5A-5B depict an alternate security box 8B that comprises a hinged edge that also comprises a locking mechanism 11 (FIGS. 6A-6B) that can be locked or unlocked to permit removal of the digital media 2 which is stored in a conventional jewel case 3. This type of security box 8B is usually transparent so that the patron, as well as the store employee, can readily see the CD or DVD directly; placing the security box 8B near an RFID reader will activate the RFID content tag 32 to reveal and confirm the contents of the CD or DVD. In order for a patron to open the security box 8B, he/she must also perform a valid rental/purchase transaction, in which case the patron, with the security box 8B then places the security box into the unlocker 30 (see FIGS. 10-11 for example) that opens the locking mechanism 11. The patron then removes the jewel case 3 from the security box 8B, places the security box 8B in a retainer bin 60 (see FIG. 1) and then proceeds with jewel case 3 to the exit. As used with the system 20 of the present invention, the security box 8B itself also comprises the security tag 34. The security tag 34 can be either an EAS tag or an RFID tag. These tags can operate in the frequency ranges set forth in the previous table.
In particular, the security box 8B comprises a lid 12 that is hinged 12A/12B to the casing 12C. The releasable locking mechanism 11 comprises a slider portion 12D (FIG. 8) that comprises an upper driver portion 12E and a lower peg rack portion 12F. When the locking mechanism 11 is locked, the pegs 12G pass through openings 12H in a tongue portion 121 of at the opening of the security box 8B. The vertical arrows in FIG. 5A indicate the direction that the pegs 12G move in order to unlock the lid 12 from the casing 12C. In order for the pegs 12G to move out of the openings 12H, the lower peg rack portion 12F needs to be displaced upward in the direction of arrows A (FIG. 6B); the lower peg rack portion 12F is driven upward by having pegs 12J (FIGS. 6A, 6B and 8) slide within the slots 12K in the lower peg rack portion 12F when the upper driver portion 12E is displaced to the left in the direction of arrow 12L in FIG. 6B. Thus, it should be understood that motion of the upper driver portion 12E is horizontal in FIGS. 6A-6B, whereas motion of the lower peg rack portion 12F is vertical in FIGS. 6A-6B. Motion of the upper driver portion 12E can be only be achieved when the lid 12 is disposed adjacent the unlocker device 48. As shown most clearly in FIGS. 7A-7C, a ferromagnetic member 12M having a projection 12N is positioned within a fairing 12P. When the releasable locking mechanism 11 is locked, the projection 12N is trapped within a cavity 12Q (FIGS. 6A and 7A), preventing any displacement of the upper driver portion 12E in the direction of arrow 12L. However, when the fairing 12P is positioned adjacent a the unlocker device 48 (e.g., magnet M with the appropriate magnetic field), as shown in FIG. 7B, the projection 12N is pulled out of the cavity 12Q (FIG. 7B) in the direction of arrow 12T, thereby allowing the user to slide the fairing 12P in the direction of the arrow 12L (FIGS. 5A and 6B) which causes the projection 12N to ride along the surface of the lower peg rack portion 12R (FIG. 8) while the pegs 12J displace the lower peg rack portion 12F upward in the direction of the arrows A (FIGS. 5A and 6B). Continued displacement of the fairing 12P in the direction of the arrow 12L eventually causes the projection 12N to enter a second cavity 12S. The lid 12 is then unlocked and the user can rotate it upward as shown in FIG. 7D to remove the contents. It should be noted that the user can manually re-lock the lid 12 by simply closing the lid 12 and sliding the fairing 12P in the direction opposite to the arrow 12L which causes the projection 12N to exit the second cavity 12S and to return to the first cavity 12Q where the releasable locking mechanism 11 is once again locked.
FIGS. 10-11 provide exemplary configurations for the unlocker device 48 of the unlocker 30 that can be used with the security boxes 8A/8B or any other type of magnetically-controlled security box. The alternate security box 8B is shown by way of example only in FIGS. 10 and 11. In FIG. 10, the unlocker device 48 comprises a surface 50 that includes a displaceable portion 52 that can be moved to form a cavity 54 and to expose the magnet M located therein. The displaceable portion 52 is driven by an actuator 56 controlled by the computer 24. Thus, if a valid purchase or rental occurs, the computer 24 activates the actuator 56 to move the displaceable portion and expose the magnet M. The patron is then prompted to position the security box 8B with the lid 12 facing downward with the fairing 12P placed into the cavity 54. Exposure to the magnet M causes the projection 12N to be pulled out of the cavity 12Q (as discussed previously) and the patron is prompted to slide the security box 8B to the right so that the fairing 12P impacts the side 58 of the cavity 54, thereby causing the upper driver portion 12E to be moved in the direction of the arrow 12L and opening the security box 8B. The patron then removes the jewel case 3 and places the empty security box 8B into a bin 60 (FIG. 1). Other variations to this include having a magnet that is displaceable and which is controlled by the computer 24. For example, the magnet can be coupled to an actuator controlled by the computer 24. In its normal position, the magnet is positioned in lower elevation, away from the surface of where the security box 8A/8B is placed by the patron. If a valid sale or rental occurs, the computer 24 drives the magnet upward to be proximate the surface where the security box 8A/8B is located to unlock the releasable locking mechanism 9 or 11.
FIG. 11 depicts an unlocker device 48 that utilizes an electromagnet 62 rather than a permanent magnet. In this configuration there is no displaceable portion 52 nor any actuator 56. Instead, the cavity 54 is always open but the electromagnet 62 is only energized by the computer 24 where a valid purchase or rental has occurred. If a valid purchase or rental has occurred, the patron is prompted to position the security box 8B with the lid 12 facing downward with the fairing 12P placed into the cavity 54. The patron then slides the security box 8B in order to move the fairing 12P, as discussed previously with regard to FIG. 10. Similarly, this alternative unlocker device 48 using the electromagnet 62 can also be used to unlock the releasable locking mechanism 9 of security box 8A.
FIG. 12 provides an example of the data stored in the database 26 in order for controlling the unlocking of the security box 8A/8B. As shown, each database record comprises digital media identification indicia (serial number, title, author, etc.). The identification of the security box, a status indicator (valid or invalid), patron identification indicia, date/time of rental and date/time of return. Except for the date/time returned, all of this information is automatically entered into the database 26 during the check-out at the checkout station 22. The default setting for the status indicator is “invalid.” If the status indicator for any security box is “invalid”, the pedestals 28 will set off the alarm if the security box passes through them. In order for the status indicator to be changed to “valid,” there must be a valid purchase or rental that occurs at the checkout station 22.
FIG. 14 provides a flow diagram of the self-check-out procedure using this two tag configuration and FIG. 16 provides a flow diagram of the self-check-in procedure using this two tag configuration. If, on the other hand, the RFID content tag 32 alone is used, with no EAS/RFID security tag 34 associated with the security box 8A/8B, then FIGS. 15 and 17 provide the self-check-in procedure and the self-check-out procedure, respectively, for such a single tag configuration.
In particular, once a patron has selected a security box 8A/8B from the business inventory, the patron proceeds to the checkout station 22. The checkout station 22 (FIG. 1) may comprise a first RFID reader 36, a point-of-sale (POS) device 38 (e.g., a coin/bill device, a credit/debit card device, etc.), a display 40, a second RFID reader 42, a power supply 44, a switch 46 and the unlocker device 48 and most of which are coupled to the computer 24. It should be noted that the power supply 44, switch 46 and unlocker device 48 can be integrated to form the unlocker 30. Furthermore, all of the components of the checkout station 22 can form an integrated station such as that sold under mark RAPICIRC® III, or the self-checkout station sold under the mark INTELLIGENT LIBRARY SYSTEM® by the Assignee of the present application, namely, Checkpoint Systems, Inc. of Thorofare, N.J.
Upon arriving at the checkout station 22, the patron places the security box 8A/8B on the designated location for the digital media 2, which is proximate the first RFID reader 36 (which is not visible to the patron). The RFID reader 36 energizes the RFID content tag 32 and retrieves all of the pertinent data about the digital media 2 being rented or purchased. This information is displayed on the display 40 to the patron who is then instructed to verify that this is the digital media that he/she has selected. Similarly, where the content tag 32 is an EAS tag, the reader 36 would comprise an EAS tag reader (e.g., Checkpoint's TR4024 pulse-listen reader).
The patron can place his/her membership card adjacent the RFID reader 36 and the RFID reader 36 can determine the patron's pertinent information and membership account. This information can be displayed on the display 40 and prompt the user to verify the information (and/or make any corrections if necessary). Once all of this data is entered correctly into the database 26, the computer 24 activates the second RFID reader 42 that energizes the RFID security tag 34 to obtain the identification information about the security box 8A/8B which should have common information with that obtained from the first RFID reader 36, e.g., title, author, etc. of the digital media 2. According to FIG. 14, the computer checks to verify if the digital media identification indicia correspond to the security box identification indicia; if not, the check-out process is terminated and the business or store manager is alerted; if the two tags' data correspond, the computer 24 initiates the sale/rental transaction itself. In particular, the POS device 38 is activated and the display 40 prompts the user to tender the proper payment and allows the user to deposit coins and/or bills into the appropriate portions of the POS device 38; in addition, the POS device 38 permits the use of credit cards or debit cards which can be received into the POS device 38 (e.g., conventional credit card or debit card readers). In accordance with FIG. 14, if the payment is tendered, the computer 24 changes the default status identifier from “invalid” to “valid” and immediately enables the switch 46 which powers the unlocker device 48. As discussed previously, the patron is prompted by the display 40 on how to position the security box 8A/8B to have it unlocked. Because the computer 24 has changed the status identifier to “valid” when the patron passes through the pedestals 28, even though the detectors in the pedestals 28 detect the RFID security tag 34, the alarm 33 is not activated because of the “valid” identifier in the database 26. Conversely, if no payment is tendered, the status identifier remains “invalid” and when the detectors in the pedestals 28 (e.g., Checkpoint StrataTM PX pedestals, etc.) detect that particular RFID security tag 34 and inform the computer 24, the computer 24 sets off the alarm 33.
It should be noted that the verification of the digital media 2 identification indicia correspond to the security box identification indicia is only necessary where the security box 8A is used since the security box 8A is typically opaque and contains printed material on its cover regarding the digital media 2 contained therein. On the other hand, where the alternate security box 8B is used, and which is typically transparent, there is no need to associate any particular security box 8B with a certain digital media 2.
Also, it should be understood that where the security tag 34 is an EAS tag, the second reader 42 would comprise an EAS tag reader (e.g., Checkpoint's TR4024 pulse-listen reader).
As shown in FIG. 15, where there is only the RFID content tag 32 used, only the first RFID scanner 36 is required. In that scenario, once the digital media 2 identification data is read into the database 26, the computer 24 initiates the sale or rental transaction and the process is similar to that discussed with regard to FIG. 14.
As mentioned previously, one of the problems patrons who rent digital media may encounter is the accrual of late fees even though they are certain that they returned the digital media to the borrowed facility well before the return time deadline. The solution to this problem is an automated check-in procedure for patrons at the entrance. FIG. 13 provides such a check-in station 122 that comprises a first RFID reader 136, a display 140 and a second RFID reader 142. The check-in station 122 also comprises a deposit bin 133, as well the bins 9H and 60. The RFID readers 136/142 are both coupled to the computer 24. In accordance with FIG. 16, when the patron returns the security box 8A containing the corresponding digital media 2, the patron is instructed by the display 140 to conduct a check-in procedure. The patron is precluded from trying to simply drop the returned security box 8A into the deposit bin 133 because the opening to the deposit bin 133 is locked and can only be opened by the computer 124 when the check-in procedure is concluded. In particular, the patron is prompted to place the security box 8A onto the designated location at the check-in station 122 which is proximate the first and second RFID readers 136/142. The RFID reader 136 energizes the RFID content tag 32 and reads the pertinent data about the digital media 2. Next, the computer 24 energizes the second RFID reader 142 to determine the security box 8A identification data. If this data corresponds to what has previously been stored in the database 26 when this security box 8A/digital media 2 was validly rented, the computer 24 enters the date/time returned into the database record (FIG. 12). The computer 24 then determines if there is an overdue condition that will be charged to the patron for returning the rented digital media. The computer 24 then changes the status identifier to “invalid” and then commands the switch 146 (which provides power from a power supply 144) to energize an actuator (not shown) to open the door to the deposit bin 133. If, on the other hand, the data of the digital media 2 and the security box 8A do not correspond, the check-in procedure is terminated and the store manager is alerted. As can be appreciated, if the patron concludes a successful check-in process, the database 26 now reflects the actual return date/time of the rented digital media, thereby preventing any possible accrual of late fees if the returned digital media were to now be used by someone else. Once the digital media 2/security box 8A are in the deposit bin, store employees can then insert a locking bar 9E from the bin 9H into the locking mechanism 9 and restore the security box 8A on the shelf.
Where the patron is returning only the digital media 2 inside the corresponding jewel case 3, there is only one tag, namely, the RFID content tag 32. FIG. 17 depicts the check-in process for that scenario. In particular, when the patron places the jewel case 3 at the designated location at the check-in station 122 and the first RFID reader 136 reads the digital media data, the computer 24 enters the date/time returned into the database record (FIG. 12). The computer 24 then determines if there is an overdue condition that will be charged to the patron for returning the rented digital media. The computer 24 then changes the status identifier to “invalid” and then commands the switch 146 to open the door to the deposit bin. Once the jewel case 3 containing the digital media 2 is dropped into the deposit bin 133, store employees can remove any of the unlocked security boxes 8B from the bin 60 and insert the jewel case 3 therein and then lock the security box 8B; the security box 8B containing the jewel case 3/digital media 2 can then be restored to the shelf.
The advantage of using this system 20 is that the media 2 (e.g., CD/DVD) remains secure and the security box 8A/8B remains unopened until a valid purchase or rental occurs. This decreases the risk of theft, improves the speed of processing material and managing the collection, which saves the rental facility money in employee hours and inventory shrinkage. It should be understood that it is within the broadest scope of the present invention 20 to use the content tag 32 for both digital media information identification, as well as for detection by the pedestals 28. In that situation, there would be security tag 34 used with the security box 8A/8B. While it is contemplated to use the RFID content tag 32 as the type of tag that the facility's antennas detect for security purposes also (e.g., unlawful removal from premises), structural limitations of these tags 32 may prevent the tag 32 from being used to emit a signal strong enough so that the security antennas in the pedestals 28 can receive a signal to sound an alarm in a reliable manner. Thus, RFID content tags 32 are commonly known as short-range tags when they are placed on material (e.g., CDs and DVDs) containing metal or ferrous content. To rectify this short range operation of the RFID content tag 32, the use of the RFID content tag 32 is combined with the use of the separate EAS or RFID tag 34 in the security box 8A/8B, or standard packing of the material (not shown) contained in a security box 8A/8B. In particular, the separate EAS or RFID tag 34 supports long range operation for detection by EAS or RFID antennas either around the business and at the pedestals 28 at the business exits.
Thus, the use of a two tag configuration, one RFID content tag 32 on the digital media 2 and one EAS/RFID tag 34 on the security box 8A/8B, can be used in the system 20 of the present invention, as discussed below.
It should be understood that the term display 40/140 is meant to cover any type of input/output device that permits the patron to perceive instructions, prompts and information from the computer 24 and to input information when requested/required. As a result, the display 40/140 can include speakers, monitors (including touch screens), television screens, etc., and includes keypads, keyboards, mouses, etc., that allow the patron to enter information.
It should also be understood that the checkout station 22 and the check-in station 122 are not limited to hard-wired configurations but can include wireless configurations such as (WIFI, Bluetooth, etc), optic protocols, or sonar protocols.
While the invention has been described in detail and with reference to specific examples thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
