Abstract

A transaction settlement device includes a processor that acquires a product code for an item being registered in a sales transaction in a customer operating mode, then checks whether the product code is associated with a sales restriction. A display screen then displays a clerk check screen when the product code has a sales restriction. The processor enters a clerk operating mode after the display of the clerk check screen for receiving a sales availability instruction and cancels registration of the acquired product code after the return to the customer operating mode when the sales availability instruction indicates purchase is not approved and permits the registration of the acquired product code after the return to the customer operating mode from the clerk operating mode when the sales availability instruction indicates purchase is approved.
