Abstract: A payment apparatus is configured to perform a payment processing for a payment related to a commercial transaction. A discharge unit discharges an article after the end of the payment processing. A sensor determines whether the article which is discharged has been removed. A controller determines whether the article which has not been removed is forgotten based on one or more predetermined conditions. A memory unit stores a transaction code identifying the commercial transaction and the article determined to be forgotten. An input device receives input of the transaction code. The discharge unit discharges the article determined to be forgotten that is identified in the input transaction code.

Abstract: According to one embodiment, an information processing apparatus includes: a readout unit configured to read out, from a storing unit, operation unit information including pieces of allocated information respectively allocated to plural operation units configured to receive selection operation; a data generating unit configured to generate print data of a code symbol display medium on which code symbols obtained by respectively symbolizing the pieces of allocated information are displayed; and a data output unit configured to output the print data to an output unit.

Abstract: According to one embodiment, a commodity information processing system includes a second reading unit, a medium issue unit, a first storing unit having sale-in-a-set information stored therein, a specific-information generating unit, a determining unit, and an issue unit. The specifying information generating unit generates provisionally-registered commodity specifying information for specifying a commodity, commodity identification information of which is read by the second reading unit. The issue unit causes, if the determining unit determines that the commodity, the commodity identification information of which is read by the second reading unit, is a target commodity of the sale in a set, the medium issue unit to issue an information display medium on which sale-in-a-set information including the commodity as the target commodity and stored in the first storing unit and the provisionally-registered commodity specifying information are displayed.
