Sales data processing method and sales data processing terminal

A terminal capable of performing a point-of-sale (POS) function at a store, comprising:

• an input device;
• an imaging device;
• a display device;
• a communication interface connectable to a server that manages the terminal;
• and
• a processor configured to:
• generate a first screen through which a particular operation can be input via the input device or a particular symbol can be input via the imaging device,
• determine an operation mode of the terminal based on the particular operation or the particular symbol that was input through the first screen, the operation mode being either a customer terminal mode in which the terminal operates as if the terminal were owned by a customer or a loaned terminal mode in which the terminal operates as if the terminal were loaned by the store to the customer,
• when the operation mode is the customer terminal mode,
• before starting a sales transaction, generate a second screen through which a store for the transaction to be performed can be selected, and
• generate a third screen through which a commodity can be registered for purchase in the transaction at the store that has been selected through the second screen;
• when the operation mode is the loaned terminal mode,
• before starting a sales transaction, generate a fourth screen through which a code of the terminal can be input;
• transmit the input code to the server that manages the terminal;
• and
• generate a fifth screen through which a commodity can be registered for purchase in the transaction at the store that has been associated with the terminal;
• and
• store display setting information about screens, items, or messages to be displayed on the terminal differently depending on the operation mode of the terminal.

A non-transitory, computer-readable medium storing a program causing a computer to execute a method for controlling a terminal capable of performing a point-of-sale (POS) function at a store, the method comprising:

• generating a first screen through which of a particular operation can be input via an input device of the terminal or a particular symbol can be input via an imaging device of the terminal;
• determining an operation mode of the terminal based on the particular operation or the particular symbol that was input through the first screen, the operation mode being either a customer terminal mode in which the terminal operates as if a terminal were owned by a customer or a loaned terminal mode in which the terminal operates as if the terminal were loaned by the store to the customer;
• when the operation mode is the customer terminal mode,
• before starting a sales transaction, generating a second screen through which a store for the transaction to be performed can be selected;
• and
• generating a third screen through which a commodity can be registered for purchase in the transaction at the store that has been selected through the second screen;
• when the operation mode is the loaned terminal mode,
• before starting a sales transaction, generating a fourth screen through which a code of the terminal can be input;
• transmitting the input code to a server that manages the terminal;
• and
• generating a fifth screen through which a commodity can be registered for purchase in the transaction at the store that has been associated with the terminal;
• and
• storing display setting information about screens, items, or messages to be displayed on the terminal differently depending on the operation mode of the terminal.
