A method of simulating device state changes in an integrated system includes receiving a transaction request from a client device, storing the transaction request as a first event in an event log, transmitting the transaction request to a terminal device, storing the transmission of the transaction request as a second event in the event log, receiving a device response from the terminal device, storing the device response as a third event in the event log, and when the integrated system is under test, a simulator replays the stored events in the integrated system under test.

A self-checkout apparatus includes a display screen, a product scanner to obtain a commodity code from a product being registered in a sales transaction, a storage unit to store journal data including product information for registered. A controller is configured to record product information for products registered in the sales transaction and output a notification of an error in the sales transaction when detected. The notification is output to the display screen and includes information regarding resolution of the error. The controller executes a first countermeasure for resolving the error, then stops the sales transaction if the error is not resolved. The controller then executes a second countermeasure after the sales transaction has been stopped and starts a new transaction if the error is resolved by the second countermeasure.

A store system includes a server and a store terminal. The server receives data based on purchased commodities respectively input in a plurality of mobile terminals. The server stores the received data based on the purchased commodities. The store terminal acquires, from the stored data, the data based on the purchased commodity input in any one of the mobile terminals. The store terminal instructs correction of the acquired data. The server executes the instructed correction concerning the stored data.

A fraudulent act recognition device includes a processor. The processor is configured to recognize an operation input relating to commodity registration in a settlement terminal by a purchaser, recognize an action of the purchaser who performs the operation input, detect, as a fraudulent act of the purchaser, a taking-out action of an unregistered commodity after an operation input for a checkout instruction is recognized, and transmit a signal indicative of the fraudulent act of the purchaser.

A weigh platter assembly includes a weigh platter having a proximal edge and a lateral edge and an off-platter detection assembly. The off-platter detection assembly has an assembly field-of-view (field-of-view) extending from the proximal edge and constrained to have an assembly central field-of-view axis substantially parallel to the lateral edge and at least one lateral boundary substantially adjacent to the lateral edge. A light emission assembly has a light source and emits a light away from the proximal edge. A light detection assembly has a light sensor and detects at least a portion of the light reflected towards the proximal edge. A controller allows the measured weight to be recorded in response to a first value from the light detection assembly and prevents the measured weight from being recorded and/or provides an alert in response to a second value from the light detection assembly.

A merchandise registration device includes a lamp, a reading device reading a symbol on an item and providing identification information for the item, a weight sensor in a table on which a scanned item can be placed, and a processor. The processor performing a registration operation including acquiring identification information for the item and comparing an expected weight of the item to a measured weight from the weight sensor. The processor controlling the lamp to indicate progress states in the registration operation and whether the reading device is ready for reading a symbol for a next item in a sales transaction.

A point-of-sale terminal is used to process purchases by a customer during normal operation. However, the point-of-sale terminal also may receive, aggregate and/or process information measured by sensors that are co-located with or in the vicinity of the point-of-sale terminal. The point-of-sale terminal may receive information from at least one sensor that indicates that the at least one sensor has sensed a measureable parameter that is outside of a threshold range; establish at least one communication channel with at least one third-party based on the indication that the at least one sensor has sensed a measureable parameter that is outside of the threshold range; and send to the at least one third party at least one communication relating to the at least one sensor indicating that the at least one sensor has sensed a measureable parameter that is outside of the threshold range.

The POS register 20 receives a withdrawal amount of cash to be withdrawn (S1), and transmits a withdrawal possibility determination request to a change machine 30 (S2a). The change machine 30 determines whether withdrawal is possible, based on the withdrawal amount in the withdrawal possibility determination request, inventory quantity data, and reserved-for-change quantity data (S2b), and transmits a determination result to the POS register 20 (S2c). When the determination result is “withdrawal impossible”, the POS register 20 notifies that dispensing of money is impossible. When the determination result is “withdrawal possible”, cash is dispensed from the change machine 30 (S9) through notification of a settlement request amount to a debit terminal 70 (S3), reading of a debit card (S4), a settlement request to a management server 100 (S5), reception of settlement permission (S6, S7), and dispensing instruction to the change machine 30 (S8).
