Description

Unattended computing system with biometric data processing {SELF-CHECKOUT SYSTEM WITH BIOMETRIC DATA PROCESSING}

The present invention relates to an unmanned calculation system with biometric data processing.

Over the past decades, point-of-sale systems have been highly automated to facilitate checkout processing. Computer-based POS systems are now commonplace in retail environments. Such systems include one or more checkout terminals (ie, checkout stations or computerized cash registers) and a database in which prices and inventory and other information related to the item to be purchased are stored. In general, each checkout includes a barcode scanner capable of detecting and placing a machine readable barcode on the packaging to identify the scanned item. When one item is scanned, the scanner sends a signal corresponding to the number of items of the item to the data processing unit of the POS system, and the POS system obtains information related to the scanned item such as price and details from the database. .

In recent years, unmanned calculating machine (self-checkout system; and the like Optical Robotics's U-Scan Express ^®) is being used. Such unmanned computing systems have self-checkout stations (generally each having a barcode scanner with an integrated balance) to allow customers to scan the barcodes of the items they purchase. The counter also includes other input and output devices (alpha-numeric keypads, video camera devices and display devices). These systems scan barcoded items, determine payment methods (e.g., credit or debit cards), and perform payments using automated payment storage (e.g., credit or debit card readers). The client can directly perform the calculations such as requesting an explanation of how to use the cashier.

The unattended counter has a signal generator (e.g., a call button or "assist" key on a keypad, phone, or other device) for use by customers when they request help. For example, the help may be requested when processing an item without a barcode. This help request can be sent to the management terminal for processing. The management terminal allows the clerk (ie, the management staff) to perform a series of management actions to supervise and control the calculations at the unattended counter. Management terminal hardware includes image display devices, touch screens, POS keyboards, PC keyboards, receipt printers and cash drawers, etc., used to display image images (e.g., image images from video cameras or other video equipment at the cash register). can do.

Management activities include providing approval when a customer purchases an item that does not have a bar code (such as agricultural products). Prior to approval, the manager may visually identify the item and enter the identification code of the item at the management terminal. Management activities also include making decisions when the unattended checkout detects a difference between the actual weight and the expected weight of an item (“weight violation”). In general, the manager's weight offense involves removing the violation or removing the item from the order (hereinafter referred to as "item invalid") to authorize the purchase and allow the customer to retry. In addition, the manager can provide the customer with an explanation of how the checkout is used and calculate the item on behalf of the customer (the item is too heavy or too large to scan with a bar code reader mounted on the checkout, or the customer can Such as when asking for help to finish). In addition, the operation or shutdown of the cashier, the monitoring of customer behavior, the use of cash drawers to collect and pay cash, the receipt of cashier's receipts, the printing of daily, weekly and monthly reports and other software or systems. It may also include administrative actions.

One challenge faced by the unmanned computing system is to comply with age-restricted sales laws and other restrictions on the purchase of certain items. For example, if a customer wants to buy alcohol or tobacco, the age of the customer must be verified before the purchase is allowed. In the standard unattended computing system, this verification is done by the clerk checking the customer's identification card (eg driver's license) when the restricted item is purchased. However, in using an unmanned calculation system, the verification by the clerk will increase the labor cost since the clerk still needs to rely on the clerk to perform the verification. Furthermore, in an environment where the clerk is not always available, the clerk's verification may cause long delays for the customer. An automated verification system is desired to reduce the costs and delays associated with age verification.

U. S. Patent No. 6,522, 722 discloses an unmanned calculation system including automated age checks. In general terms, US Pat. No. 6,522,722 discloses a fixed position unmanned computing terminal comprising a biometric sensor (eg, a fingerprint sensor) used to receive customer-identified biometric data. As disclosed in US Pat. No. 6,522,722, when an age verification is required, a unique identification code (e.g., store loyalty card number or credit card number) is entered by the customer only for a particular customer, which is the customer. It is used as a key to retrieve the biometric profile associated with. The biometric input data is input through the biometric sensor of the terminal. This input data is then compared with the data in the biometric profile to verify the identity of the customer. Although the age verification system of No. 6,522,722 may be useful, other automated age verification systems are still desired.

Some unmanned computing systems include a video surveillance system that allows managers to supervise or assist customers in their calculations. In an unattended counter, a video camera can be used to capture an image of an item without a barcode, for example for display at a supervisor station. This allows managerial employees to view the item and enter the appropriate code.

Many unmanned computing systems are described, for example, in US Pat. Nos. 5,083,638, 5,115,888, 5,123,494, 5,125,465, 5,168,961, and the like.

<Overview of invention>

The present invention provides an unmanned calculation system. The system includes one or more customer bases (ie, checkout counters) and a predetermined number of management bases (ie, management terminals). Each management terminal operates to perform a corresponding group of management actions for work at the cashier.

The management terminal has a network interface for communicating with at least one checkout counter via at least one of an electrical medium, a radio frequency (RF) medium and an optical medium. The unmanned computing system can support various types of management terminals, such as fixed management terminals and mobile management terminals (e.g., provided by using a portable computer coupled with a wireless network). In addition, it may include a professional management terminal having a limited user input device. For example, a "wireless pager size" management terminal that is small enough to be worn by a user may be provided to alert the clerk. The administrator then knows when to return to the physical proximity of the system.

A plurality of management terminals may be provided to allow management staff to select and use the management terminal having the best convenience or utility under certain circumstances. The plurality of management terminals may include a fixed management terminal, a specialized fixed management terminal, a mobile management terminal, and a portable mobile alert management terminal. Each terminal type can be provided with different input and display peripherals. For example, the terminal may include a keypad, a touch screen, a still and moving image input device, a signature capture interface, and a biometric information input device such as a fingerprint sensor. Biometric information input devices may also be used, such as iris recognition, facial recognition, speech, voice recognition and other unique physical and behavioral characteristics.

Several different management terminals can be provided to provide increased flexibility in management of unmanned computing systems. For example, if a weight violation occurred at one checkout while the manager was physically located at the other checkout, the manager does not need to return to the fixed management terminal to provide a management action. Instead, an administrator can eliminate the breach by reading a transponder card to a transponder card reader mounted on the cashier or at a specialized fixed terminal located near it. At this time, if at the same time the manager still asks for approval of the bar code-free item at another checkout while still providing support for the weight violation, the manager may take the mobile management terminal out of his pocket, for example, The approval may be provided while viewing the missing item.

The management communication controller may control communication between the cashier and the management terminal to prevent the management signals that are opposed to each other (e.g., if different managers at each of the different management terminals enter control opposite to the customer terminal). time). Similarly, if a customer signature is required but the unattended checkout counter used by the customer does not have an operating signal capture device (due to a failure of the device or the checkout does not just have a signature capture), the message is captured. It may be delivered to one or more mobile terminals with an input device, and the user may provide the signature at the mobile management terminal.

The administrator can select from a plurality of management terminals having different physical characteristics, thereby enabling them to respond more quickly to situations requiring administrator coordination. This saves managers the time spent on unattended counters and each order. In addition, this adjustment of management behavior may save administrators the down time spent monitoring the system while the cash register is not in use. This is achieved by selecting a management terminal that meets the needs of the situation in the maneuverability and efficiency of the human-machine interface. For example, by using a mobile alert management terminal, an administrator can leave the physical proximity of the unmanned computing system when the customer is not present or management action is not required. This enables efficient use of management staff resources.

In an unmanned computing system, each management terminal can provide various combinations of corresponding maneuverability and practical perfection with respect to a group of possible management actions. Management staff may select from a variety of management terminals available at any time to provide a response to situations in which management coordination is required.

1 and 2, the unmanned computing system 100, 200 may include one or more checkout counters 110-113, 210-213 coupled to a plurality of management terminals 126-132, 226-232, respectively. have. Each management terminal may perform management control of the checkout counter. The terminals 126 to 132 and 226 to 232 are on or at the checkout counter as well as the " standard size " terminals 130 and 230, the mobile terminals 131 and 231 and the pager size terminals 132 and 232. It may include a small terminal (126 ~ 129, 226 ~ 229) mounted in the vicinity. In some cases, one terminal (eg, 126-129, 226-229) may have a specific function, such as the elimination of a transaction. For example, the terminal 126 may be equipped with a transponder-card reader to allow an administrator to remove a transaction by simply reading the security card into the reader, or by using a biosensor (eg, Fingerprint sensor) to enable customer identification or automated age verification processing.

The control signals exchanged between the checkout counter and the management terminal are managed by the management communication controllers 122 to 125 and 222 in order to adjust the control of the checkout counter by the management terminal and to instruct an opposite control. 1 shows one embodiment in which controllers 122-125 are locally connected to each counter 110-113, and FIG. 2 shows one embodiment in which a central controller 222 is used. The central controller 222 may be coupled to the checkout counter by a data network (eg, Ethernet, Token Ring or IEEE 802.11b network), while the premises controllers 122-125 may be connected to the hardware and software system of the checkout counter. It can be an integrated device.

When management control of the counter is requested, the signal processing circuits 114 to 117 and 214 to 217 of the counter, including, for example, microprocessors, data storage and other hardware, software, and combined interfaces, etc. Generates a management request message that is forwarded to the management communication controller (122 to 125, 222). The management request message may include data indicating the nature of the requested management support. For example, the management request message may include a parameter indicating that the message has been generated in response to the customer pressing a "help" button or detecting a weight violation at the cash register. Other management actions may also be reported. At this time, the communication controller allocates the management request message to the management terminal (in some embodiments, the format or content of the message is modified before the assignment, so that the message parameters are processed by the communication controllers 122 to 125 and 222). May be).

In FIG. 1, the unmanned calculation system 100 includes premises management terminals 126 to 129 and sharing terminals 230 to 232. Each of the campus management terminals 126 to 129 is directly connected to a corresponding counter 110 through 113 through the campus communication controllers 122 through 125 of the checkout counter to control the directly connected checkout counter. Each shared terminal 130 to 132 is coupled to a plurality of checkout counters to switch and control the plurality of checkout counters 110 to 113. When a management action is requested, for example, at the checkout counter 110, a signal (i.e., a data message) is sent from the checkout controller 122 to the corresponding premises terminal 126 as well as to the shared management terminals 130-132. The signal is processed at the management terminal to generate an alert informing the administrator of the need for assistance. In addition, the signal may identify the specific action requested. In some embodiments, the controllers 122-125, 222 manage interactions with the plurality of management terminals such that an initial response from the management terminal is received in response to a request for help.

In FIG. 2, like the unmanned calculation system 100, the unmanned calculation system 200 includes premises management terminals 226 to 229 and shared terminals 230 to 232. However, in the unmanned computing system 200, coordination of management actions to control and assist customer calculations is provided using one common central communication controller 222 instead of a plurality of campus controllers 122-125. The management terminals 226 to 232 communicate with the checkout counters 210 to 213 through the central controller 222.

The communication controllers 122 to 125 and 222 transmit one request to the sharing management terminals 130 to 132 and 230 to 232 so that each sharing management terminal 130 to 132, 230 to 232 receives the request. For this purpose a "broadcast" request may be used. Alternatively, the communication controllers 122 to 125 and 222 may generate each single message and transmit it to each terminal. In addition, the communication controllers 122 to 125 and 222 send a request to the terminals 126 to 229 and 226 to 229 so that only the terminal directly connected to the requesting customer's checkout counter receives the request. At this time, the controller waits for a response from the management terminal. If a response is generated by a plurality of management terminals (eg, each of the plurality of managers attempts a response), the communication controller performs an arbitration function to determine one or more responses to be used to control the cash register. do. In one embodiment, the controller may simply accept a response from the management terminal that initially responds. In some cases, additional responses may be approved if appropriate and not in conflict with the original response, but are ignored if no longer appropriate (e.g., for a violation of weight already removed). Alternatively, a timeout description may be used to determine when the remaining request is no longer appropriate. For example, after the first broadcast of a management request message, the controller may rebroadcast the request every 100 milliseconds until the management terminal provides a response. If the management terminal does not receive at least one request within the timeout time (eg, within 500 milliseconds), a timeout occurs. That is, since the management terminal can assume that the request has been answered by another management terminal, the management terminal no longer accepts an input corresponding to a timed request (for example, the request is made by the management terminal. Removed from the list of remaining managed requests). In the unmanned computing system 200, the responses are redistributed through the central controller 222, while in the unmanned computing system 100, the management terminals deliver the responses directly to the communication controller of the counter.

For example, the broadcast request message may be assigned to the management terminals 126 and 130 to 132 to inform the managers of the customer's help request. After the broadcast request is sent, the controller 122 waits for the first one of the various management terminals to respond (ie, accept the request). In some embodiments, upon receiving a notification from the first terminal (eg, terminal 132) that it has received a broadcast request, the controller 122 may not have yet received terminals (eg, 126, 130-). Message to remove the remaining broadcast requests. As a result, it is possible to prevent the lagging management request from remaining on the screens of the terminals 126 and 130 to 131 that have not yet been received. Once the broadcast request is received at one terminal, the controller 122 may store data identifying the received management terminal and then control the data flow between the customer checkout 110 and the management terminal.

In addition, the management of the checkout counter may be initiated by any one of the shared management terminals 130 to 132 and 230 to 232 or the premises management terminals 126 to 129 and 226 to 229 of the checkout counter. This can be done without the need to request management actions from the cashier. Control of the checkout counter may be initiated using a switch, button, software command or other checkout counter selector for selecting the checkout counter under control at the management terminal. For example, FIG. 5, described below, illustrates an interface for selecting one of four calculation paths (ie, checkout counters) to control. The management terminal then initiates contact with the calculation system to be controlled. In the unmanned calculation system 100, the management terminals 130 to 132 initiate direct communication with the controllers 122 to 125 of the selected checkout counters 110 to 113. In the central controller system 200, the terminals 126 to 132 transmit a request to the controller 222, and the controller 222 coordinates management actions to communicate signals between the management terminal and the counters 210 to 213. It will be provided to start. In some embodiments, the manager may switch the checkout counter which can be controlled at any point by using the checkout selector.

Different controller embodiments may use different algorithms or modes to allocate and adjust signals between the management terminal and the cash register. In some embodiments, all management terminals can be activated at the same time. Therefore, the management staff can use any management terminal without restriction or delay. In addition, some management terminals may be suspended in order to prevent third parties from unauthorized or improper use of the system. And, the management staff can operate it before using the terminal is suspended. Activation can be either explicit by the use of a key or by encryption, or implicitly by reading a transponder or magnetic card into a reader on the terminal (126-129, 226-229) to invalidate the item. May be

The management terminal is provided with an input device (eg, keypad, touch screen, button or switch) so that the administrator can start or stop using the terminal. The input generates a corresponding signal which is transmitted via the communication network 101, 201 to the management communication controllers 122-126, 222. In response, the communication controller may accept an input from the management terminal or block an attempt to connect (such specific response depends on the current mode of operation). The controllers 122 to 126 and 222 and the systems 100 and 200 may support various adjustment modes between the cashier and the management terminal. Typical adjustment modes include simultaneous mode, mutually exclusive mode, priority mode, and mixed mode.

In the simultaneous coordination mode, all management terminals of the unmanned computing system 100, 200 can be activated for use. Thus, there is no specific signal generated when the administrator decides to switch between management terminals. In mutually exclusive mode, only one management terminal is active at a time to control the cashier. Thus, in mutually exclusive mode, one management terminal can receive and process commands for the cashier only when the other management terminal is not activated to control the cashier. A display device or an image display may be provided to indicate the activated or deactivated state of the terminal. The priority mode is a variation of the mutually exclusive mode. In the priority mode, the controllers 122 to 126 and 222 deactivate all currently managed terminals in an attempt to activate one management terminal. However, if the currently active terminal is processing an action that cannot be interrupted and rejects the attempt, the attempt may fail (that is, the controllers 122 to 126 and 222 reject the attempt). Mixed mode is essentially mixed mode or priority mode, but it is characterized in that any other management terminal is activated at the same time. For example, a mixed mode may be entered to cause the small mobile alert management terminal 132 to warn the administrator of the start of customer behavior at the cashier 110.

Special fixed management entries 126-129, 226-229 may be provided for the case where the manager is in physical proximity to the cash register, for example. The administrator can use the terminals 126-129, 226-229, for example, by reading the transponder card to approve the weight violation. In addition, other input devices such as keypads or key switches may be used in the terminals 126 to 129 and 226 to 229. In some embodiments, for example, in FIG. 1 each terminal 126-129. 226-229 can be used to provide support for a particular checkout counter. In another embodiment, the terminals 126 to 129 and 226 to 229 may control a plurality of checkout counters.

The unmanned computing systems 100 and 200 may support a group of management terminal types that provide various other functions. For example, terminals 132 and 232, such as fixed terminals 130 and 230 of standard functions, mobile terminals 131 and 231, and portable wireless pagers of special functions may be used. The mobile management terminals 132 and 232 may be based on a barcode reader, a touch screen, a voice generator, and a laptop or portable battery powered computer having a wireless communication capability. In addition, portable movement warning management terminals 132 and 232 may also be provided. Features supported by a particular terminal type may vary depending on size, price, power capacity, convenience, security and other reasons.

Portable mobile alert management terminals 132 and 232 may be implemented using a pager sized device. The pager-sized terminals 132 and 232 are powered by battery power and communicate wirelessly with the unmanned computing system via the wireless network interfaces 101 and 201. In some cases, each communication controller 122-125, 222 may be provided with an interface connected to a standard radio calling network to transmit and receive signals through a conventional radio calling network. Terminals 132 and 232 may display, for example, short strings indicating the operation of an unmanned computing system or may include vibration or other voice / image devices. The indication may be generated when using a checkout counter or upon request for a management action from the checkout counter 110. A pager-sized device can be used, for example, for general monitoring purposes (for example, to warn the monitor when an administrator is not in the physical proximity of the checkout counter, etc.).

In some embodiments, the management terminal may be provided with an interface device that is selected relatively limited. For example, a mobile or pager-sized device may use the smaller keypad of FIG. 7 rather than a standard size POS keyboard. In these embodiments, unattended computing systems 100 and 200 may provide context-sensitive prompting to support a series of administrative inputs using keypad 700. 3 and 4 illustrate a management control process that can be used to process management input using a terminal with a small size input device.

3 and 4 are flowcharts illustrating a data processing process that may be used in embodiments of the unmanned computing system 100, 200 for processing management data to control a cashier. The process 300, 400 is suitable for use in a management terminal with limited display and input capacity. For example, a terminal having only a simple touch screen interface can be used. 5 to 7 show representative touch screen interface display devices that can be used in portable mobile terminals. The process 300, 400 enables the display and input of a management request to an administrator using the display apparatus 500, 600, 700.

The process 300 is initiated when the management terminal is activated (ie, powered on). The first step performed by the terminal is to determine if the administrator's adjustment is requested (step 301). This determination may be based, for example, on data exchanged with the communication controllers 122-126, 222 to determine if there are still management requests remaining. If mediation is not requested, the route (ie, counter) selection screen 500 may be displayed to allow the administrator to initiate control of the counter. On the one hand, if management intervention is requested, a message request coordination is displayed on the management terminal (step 302). In this case, the terminal may display a path selection screen 500 to allow an administrator to accept the request or to start control of another terminal (step 303). If there is a remaining mediation request, the text display area 501 of the screen 500 may indicate an indication of the request.

At this time, if there is a request remaining, the administrator may use the key 700 of the terminal to ignore the request, select a path to service, select another path to control, or terminate the program (ie The request may be denied) (step 304). If the administrator rejects the request (ie, selects the "end program" function or the reject key) (step 305), the corresponding signal is sent to the controllers 122-126, 222 and the terminal is in normal operation mode. To return. In some embodiments, the controllers 122-126, 222 may send a rejected request to another management terminal or resume the request.

On the one hand, if the administrator receives a service request from the route, the terminal determines whether the request is about a simple process that can be marked as a weight violation and responds using a certain display interface, or more. Determine if complex prompting is needed (step 306). If a weight violation occurs, for example, the weight violation screen 600 (FIG. 6) is displayed (step 308). The interface 600 remains in display until the violation is removed by the customer or another management terminal (step 309). If the violation is eliminated by another third party, this may be determined based on the message exchanged between the terminal and the controllers 122 to 126 and 222. The management response may be entered using the interface 600 including the selection of an "Override" or "Later" function. If the " ignore " function is selected (step 310), a signal is sent to the controllers 122-126, 222 to invalidate the weight violation (step 311). If the violation has already been eliminated, or after the administrator selects the "later" or "ignore" function, the process resumes at step 301. In some embodiments, other requests may be processed using a simple display screen such as used for weight violation processing.

If the request is not just a simple process of requesting a simple input (such as a weight violation), the "mini direct mode" interface described in ongoing application 10 / 060,423 may be implemented (step 307). The " mini direct mode " interface can use an interface as shown in FIG. 7, providing context-dependent prompting so that a series of management functions can be performed using relatively simple input and display devices.

The system 100, 200 may include a terminal with a fingerprint sensor (or other biometric sensor) used to perform an automated age verification system. 4 shows a flowchart of the automated age verification process. As each item is scanned by the customer during the unattended calculation (step 401), the unattended calculation system queries the database records related to the item to determine whether the item is an age restricted item (step 402). Data identifying whether the item is age restricted may be stored in the same database along with price and other item data.

If the item is not age restricted, normal processing procedures, i.e. purchase of the item, are allowed (step 404). If all of the customer's items have been scanned (step 405), the customer can complete the transaction (eg by entering a credit card for payment) (step 406). If the scanned item is age restricted, the system determines if the age of the customer has already been verified, for example in connection with listing of another age restricted item (step 403). If age verification is required, the client is prompted to enter his date of birth ("DOB") (step 407). The DOB is used as a key to retrieve all database records with a matching DOB ("candidate record") (step 408). Each candidate record contains the data characteristics of the fingerprint ("biometric data").

The system then causes the customer to place a finger on the fingerprint sensor 502, and upon the customer doing so, the system immediately sends the fingerprint of the customer's fingerprint (" target biometric data &quot;) from the sensor 502. The data characteristic is received (step 409). The target biometric data is then compared with the biometric data in each of the candidate records to determine whether there is a match (steps 410 and 411). If there is a match, the purchase of the item is allowed (step 404). If the target biometric data does not match the biometric data in all the candidate records, exception processing occurs (step 412).

Exception processing may include, for example, directing a customer to a fixed cashier position for identification, or alerting a clerk to assist the customer using a mobile terminal. After the customer's age is verified by the clerk and the purchase of the customer is permitted, the cashier or the clerk scans the customer's fingerprint again to verify that it is correctly verified against the original fingerprint (ie, subject biometric data). Check. If the verification is successful, the clerk instructs the system 100, 200 to store the subject biometric data and the customer's DOB in a new database record for use in future purchases. If the cashier is unable to verify the age of the customer (e.g., the date of birth entered by the customer does not match the date of birth on the identification card, or the identification card is not valid), the customer Is rejected, and the system directs the clerk to preserve the item.

In some embodiments, the system allows the customer to reject fingerprint input at step 409. For example, in step 409 the system displays a text indicating that age verification is required and touches a button to call a clerk to assist (eg, a "call clerk for age verification" button). Can be displayed as If the customer rejects the fingerprint input at step 409, exception processing (step 412; ie manual verification) occurs. If the customer hesitates to enter fingerprint data in exception processing (step 412), no new database record is stored to store this data.

In some embodiments, additional data may be included in other systems, while the DOB / biometric record (ie, "candidate record") only stores date of birth and biometric data. In this embodiment, the system does not need to store additional customer identification data (eg, name, address and other identification data) for the age verification process. Age verification can only be performed by comparing subject biometric data with biometric data in a group of candidate records (all of which are retrieved using the same DOB key). This feature can alleviate customer security and privacy issues.

In addition, the system 100 or 200 may include terminals capable of automatically capturing identification information such as a signature. 8 shows a flowchart of an identification capture process implemented using a mobile management terminal. The process (step 800) can be used, for example, to complete a credit payment transaction that requires the capture of a customer's signature or other identification. The process (step 800) may begin after the customer has unattended calculated the item to be purchased and the purchase has been instructed to pay using a credit account.

The process (step 800) starts at the same time as the mobile terminal receives the management request message. Steps 301 to 305 of FIG. 8 relate to a path selection operation and may be implemented in substantially the same manner as described with respect to steps 301 to 305 of FIG. According to the path selection, the terminal determines whether the management request message relates to the identification capture (step 806). If the request is not about identity capture, the terminal proceeds to another appropriate process (step 807). For example, if appropriate, the terminal can proceed to processing step 306 of FIG.

If the management request is about identity capture, a suitable screen or control interface is displayed (step 808). In the case of signature capture, the interface may be similar to the interface screen 900 of FIG. 9. The interface 900 allows a user to manually enter a signature on a touch-sensitive display screen. In the case of an image image identification, the terminal may be equipped with a small integrated video camera, and the display screen may be a window indicating a preview of the captured image. In the case of a fingerprint capture terminal, the interface instructs the user to place a finger on the fingerprint sensor associated with the terminal. In addition, other interfaces may be used.

If customer identification data has been successfully captured (e.g., selecting " O.K. " button 901), the data can be returned to a store controller or an unattended checkout (steps 809 and 810). Upon successful receipt of the identification data, the terminal may complete the processing of the credit transaction and store the captured identification data in a database for future verification purposes (ie, as evidence for customer authorization). On the other hand, if the capture of the identification data is unsuccessful (eg due to a timeout or by selecting the "Cancel" button 902), a capture failure message is reported to the controller. The controller can then perform exception processing to request other forms of payment from the customer, display a warning message on the management terminal, or resume the capture operation on the other management terminal.

Various modifications and modifications can be made to the processing steps 300, 400, and 800. For example, the interface may be returned to accept more input in all cases except when pressing the "Cancel" button instead of returning to normal operation. The display of the weight violation screen 600 may be replaced by entering the simple management mode 400 in the weight violation context. Thus, pressing the "Enter" button confirms the scanned item and pressing the "Cancel" button causes the mobile management terminal interface to exit the simple management mode and return to normal interface operation.

Numerous embodiments have been described in the present invention.

Nevertheless, various modifications may be made without departing from the spirit and scope of the invention. For example, the network interfaces 101 and 201 for connecting the controllers 122 to 126 and 222 to the management terminal may use standard networks such as Ethernet and IEEE 802.11b data networks as well as private networks, and also multiple networks. It can include a type. Thus, other wired and / or wireless electrical connections (eg, infrared, radio waves, etc.), chip level connections may be used.

The steps of the process 300, 400, 1000 may be performed in a different order, additional steps may be added, or some steps may be deleted. For example, step 409 may occur before step 408 in process 400. In addition, although implementations of the system have been described that use biometric information for the unattended calculation of age restricted items, embodiments may use biometric information to determine if other forms of limited purchase may occur. Accordingly, other embodiments are also within the scope of the claims.
