The peripheral-request control signal including instructions for operating a retail peripheral device. The method also includes the step of generating a dispenser control signal in response to the detecting step. Moreover, the method includes the step of operating a currency dispenser so as to dispense an amount of change due to a customer in response to the dispenser control signal. The currency dispenser is distinct from the retail peripheral device. A checkout terminal is also disclosed.

Abstract: A system modifies the status of a surveillance tag indicator in a product data record corresponding to an article being processed at checkout stand. The system comprises a product database having product records corresponding to articles sold in a store, a surveillance tag interrogator associated with the checkout station that generates a surveillance tag present signal in response to detection of a surveillance tag, and a database modifier communicatively coupled to the database and the interrogator for modifying a surveillance tag indicator of a product record in response to the surveillance tag present signal from the interrogator. The database modifier, in response to the surveillance tag present signal, may set the surveillance tag indicator of a product record corresponding to an article being processed for checkout to indicate a surveillance tag is expected for the article thereafter.

Abstract: A system provides a more robust measurement of scanned items at a self-checkout station. The system comprises an item verifier for verifying placement of an item on a scale of a self-checkout station and a measurement adjuster operatively coupled to the item verifier for adjusting the item verifier operation in response to an error signal from the item verifier. In one embodiment, the measurement adjuster increases the number of samples for determining the weight of an item. By increasing the number of samples collected before determining item weight, the probability that temporary vibrations will not disturb weight measurement is increased. An exemplary method to implement the system includes verifying placement of an item on a scale and adjusting the weighing of the item in response to a failure to sense a weight that corresponds to the item placed on the scale. The adjustment may include increasing the number of samples collected or the time between samples.

Abstract: A system for verifying deactivation of an EAS tag at a self-checkout counter includes an electronic article surveillance (EAS) tag deactivator for deactivating EAS tags attached to articles processed at a checkout station and an EAS tag interrogator associated with the checkout station that generates an electronic checkout disable signal in response to detection of an EAS tag by the EAS tag interrogator. The checkout disable signal may be used to disable the operation of a self-checkout station component so that the consumer is unable to process additional articles until the EAS tag deactivation operation is successful. The generation and use of the checkout disable signal helps ensure that a consumer at a self-checkout station deactivates all EAS tags attached to articles processed at a self-checkout station during checkout. The checkout disable signal may be sent to the processor of the terminal of the self-checkout station to cause the processor to disable components of the self-checkout station.

Abstract: A system facilitates the collection of reliable data for computing a new weight associated with an item identifier in a database for operating self-checkout stations in a store. The system includes an authorized personnel identifier for identifying authorized personnel scanning an item and a provisional weight multiplier operatively coupled to the authorized personnel identifier for multiplying a contribution of a sensed weight for the scanned item to a new weight computation for the scanned item. The system preferably counts a measured weight for an item scanned by a store attendant as two or three measurements in collecting the number of weight readings required for establishing a new weight for an item identifier. Thus, the system utilizes the more trustworthy data obtained by a store employee to confirm a new data value without significantly jeopardizing the integrity of the new data value computation.

Abstract: A system, method and/or apparatus aids in preventing duplicate bar code entries in an item security database. Bar codes from items that vary with respect to a security characteristic such as a non-weight characteristic are compiled into a custom bar code format or template that is stored in a custom bar code format file. An obtained bar code from a scanned item is compared to the custom bar code format. If the obtained bar code compares to the custom bar code format, the bar code is manipulated according to the custom bar code format. The manipulated bar code is used to retrieve a security characteristic (value or data) regarding the scanned item and/or to create a bar code entry with an associated security characteristic if the bar code entry is not in the item security database.

Abstract: A system determines the physical configuration of a convertible checkout station and configures the software to operate the station in correspondence with the determined configuration. The system comprises a physical configuration actuator that responds to a checkout station physical configuration and a physical configuration signal generator responsive to the actuator to generate a signal identifying the physical configuration of the checkout station. The physical configuration actuator may be tab, mounted member, or the like. The signal generator may be a plunger switch that is mounted to a checkstand, sliding drawer, or scanner of the station. The actuator engages the switch to generate a first signal when the station is physically configured for one operational mode of the station and releases the switch to generate a second signal when the physical configuration of the station is changed for operation in a second operational mode.

Abstract: In a retail self-checkout system, a customer places an item to be purchased into an itemization area. The system identifies the item by using an item detector/scanner or, alternatively, through a customer input at a touchscreen display or other suitable device. The system then determines whether the item satisfies predetermined security criteria to ensure that the item in the itemization area is in fact the identified item. If the item satisfies the security criteria, the system deactivates a security tag affixed to the item to be purchase. If the item fails to satisfy the security criteria, an alarm summons store personnel to provide human intervention in the self-checkout process.

Abstract: A method of operating a retail system which has (i) a self-service checkout terminal, and (ii) a remote supervisor terminal includes the step of generating an intervention-needed control signal with the self-service checkout terminal if a user of the self-service checkout terminal requests intervention from retail personnel operating the remote supervisor terminal during a checkout transaction. The method also includes the step of transmitting the intervention-needed control signal to the remote supervisor terminal. The method further includes the step of generating a request-acknowledged control signal with the remote supervisor terminal in response to receipt of the intervention-needed control signal. Moreover, the method includes the step of suspending the checkout transaction of the user in response to generation of the request-acknowledged control signal. A self-service retail system is also disclosed.

Abstract: The present invention provides a self-checkout terminal having input and output devices for performing a self-checkout process. The input and output devices are controlled and monitored by system software that determines, based on its monitoring of the input and output devices, whether intervention by store personnel is necessary. The system software further controls a voice modem that provides a digital audio signal output to a store intercom system, and has access to digital audio files containing announcements to be played on the store intercom system. When the system software determines that intervention by store personnel is necessary, it selects an appropriate digital audio file and plays the digital audio file over the store intercom system by means of the voice modem.

Abstract: A method of monitoring item shuffling in a post-scan area of a self-service checkout terminal having a post-scan shelf, a bagwell with a grocery container positioned therein, and a weight scale positioned so as to detect weight of items positioned both on the post-scan shelf and in the grocery container, includes the step of detecting removal of a first number of items from the post-scan shelf with the weight scale and generating a first weight decrease value in response thereto which corresponds to the weight of the first number of items. The method also includes the step of detecting placement of a second number of items into the grocery container with the weight scale and generating a first weight increase value in response thereto which corresponds to the weight of the second number of items.
