A method includes: acquiring, from a store terminal via a network, limited product information indicating a limited product for which a time available for sale in one branch store corresponding to the store terminal is limited; acquiring, from a communication terminal of a user via the network, i) a request for a purchase menu of affiliated stores and ii) a branch store identifier (ID) specifying one branch store corresponding to a device ID specifying a beacon signal transmitter disposed in the one branch store; generating, based on the limited product information, the request for the purchase menu, and the branch store ID, privileged purchase menu information corresponding to the one branch store; and outputting the privileged purchase menu information to the communication terminal.

An accounting system according to the present disclosure includes a terminal that is placed on a table used by a customer, a connection apparatus that is connected to the terminal at the time of accounting, and a server that communicates with the terminal and the connection apparatus via a network. The terminal receives an order for a product from the customer and then transmits table identification information by which the table can be identified and product information regarding the product to the server, the server stores the table identification information and the product information in association with each other as accounting information, and the terminal acquires, when it is connected to the connection apparatus, the accounting information associated with the table identification information from the server and performs accounting processing.

In order to improve efficiency of an operation of a cash handling system and reduce the labor required for the operation, a POS register receives an input of a cash-out amount, and an input of a charge amount. The POS register reads a debit card ID from a debit card, and transmits a settlement request including the debit card ID and a settlement amount to a management server. Upon receiving the settlement request, the management server withdraws the settlement amount from an account, and transmits a settlement permission to the POS register. Upon receiving the settlement permission from the management server, the POS register performs charge of electronic money, and transmits a dispensing instruction for the cash-out amount to a change machine. The change machine receives the dispensing instruction and dispenses cash.

A sales-data processing device includes: a registering circuit that registers a product and generates registration data; a settlement processing circuit that executes settlement processing using the registration data; a sending circuit that sends the registration data to another sales-data processing device for execution of the settlement processing by the other sales-data processing device using the registration data; and a prohibiting circuit. Once the sales-data processing device has determined that the sending circuit will send the registration data, the prohibiting circuit prohibits the settlement processing circuit from executing the settlement processing before the sending circuit sends the registration data.

A settlement system with higher security which replaces a settlement system using credit cards is provided. The settlement system has a user terminal, a settlement device, and a settlement terminal. First, a user ID, a password, and upper limit amount information identifying an amount are inputted in a user terminal 100 (S912), and sent to the settlement device (S913). The settlement device performs credit determination (S922), generates temporary permission information if credit is possible (S923), and sends the temporary permission information to the user terminal (S924). The user terminal generates a one-time password (S915). The one-time password is inputted to the settlement terminal (S931). If the one-time password sent from the settlement terminal to the settlement device is identical to the one-time password created in the settlement device, the settlement device allows a user's payment (S928).
