Abstract: A transaction processing system for retail stores includes a content management apparatus storing content files and a transaction processing apparatus. The transaction processing apparatus is configured to register a commodity in a transaction based on registration input received from a user terminal device and select a content file to be displayed on the user terminal from the content files stored on the content management apparatus. The content file is selected based on a user attribute associated with a user of the user terminal device or a commodity registered in the transaction. When a length of time since a registration input was last received without another registration input or user instruction being received exceeds a timeout period, the transaction processing apparatus causes the user terminal device to display information corresponding to the selected content file.

Abstract: A data management device includes a network interface, a memory storing first and second databases, and a processor. The processor determines whether a customer identifier has been included in receipt data. When the identifier is included, the receipt data is stored in both databases. When the identifier is not included, receipt data is stored in the second database. The processor searches the first database for receipt data including a customer's identifier upon request and controls the interface to transmit the receipt data found by the search to the customer terminal. If a search request is received from a server, the second database is searched for receipt data that satisfies a search condition accompanying the request, and then receipt found in the search is transmitted to the server.

Abstract: A data processing apparatus determines whether a condition for issuing a stamp is satisfied based on receipt data, and issues a stamp if the issuing condition is satisfied. If the stamp is issued, the data processing apparatus updates data of a stamp card, which is stored in association with customer specifying information, to data of the stamp card indicating a result of collecting an issued stamp. The data processing apparatus associates card identification information for identifying a stamp card of which the data is updated with the receipt data. The data processing apparatus performs control to cause to display, on an information terminal possessed by a customer, a receipt image based on the receipt data and the image of the stamp card identified by the card identification information associated with the receipt data.
