Title: Shopping support device and shopping support program
IPC: G07G1/12
Filed: 2021-11-18
Abstract: PROBLEM TO BE SOLVED: To allow consumers to switch between operation for use in shopping support and operation that is restricted to authorized persons. 
     SOLUTION: A shopping support device acquires store-specific setting information. The shopping support device determines, based on the setting information, whether a control mode is a first mode for shopping support at the store or a second mode for business restricted to the operation of an authorized person. When the first mode is determined, the shopping support device controls shopping support operation by a shopping support program based on the setting information. When the second mode is determined, the shopping support device controls the execution of the business restricted to the operation of the authorized person.
