To solve the problem that it is inconvenient that a customer is notified of only the unit price and the total price is calculated at a cash register only at the end of shopping, that is, there is no mechanical method to instantaneously provide the total price during shopping on a display screen or by voice, while requiring an operator to input each price for settlement and requiring time and cost for reading bar codes.

The problem can be solved by a structural combination of a (numbered) shopping basket with radio input output and a sensing computing function, voice and display screen digital camera provided on the shopping basket, a store internal structure system, and the like.
