I was doing. For this reason, all customers waiting for settlement make a turn at the settlement place P.

Here, the time required for checkout at the POS terminals 2 and 2a is shorter as the number of products to be checked out is smaller.

However, in the conventional case, since all customers waiting for payment are waiting at the payment place P, there are a large number of customers waiting for payment, or customers in front of the customer purchase a large amount of merchandise. In spite of the fact that a customer purchases a small number of products, this customer needs a long waiting time and stresses the customer who purchases a small number of products, "I am going to finish soon". However, there was a problem that the image of the store was down.

By the way, the POS terminal 2a arranged at the place Q other than the settlement place P usually does not handle check-out for a plurality of products, so that the POS terminal 2 arranged at the settlement place P becomes crowded. If there is, it may be vacant.

In the self-checkout system 1 of the present embodiment, using the above-mentioned tag receipt 30, it is possible to perform the checkout at the POS terminal 2a arranged at the place Q other than the settlement place P.
