First Claim
1. A method for a system including a plurality of first cards each having a first memory and respective first signal, a second card, a first computer that receives from the second card, and a store including a plurality of products, a central computer, and a checkout station having an electromagnetic detector and a checkout computer, the method comprising the step of:
- sending a second signal to the first memory of a card in the plurality of first cards, the second signal corresponding to one of the plurality of products, and the following steps, performed in the store, of;
communicating product data between the central computer and the checkout computer;
receiving the first signal from the card in the plurality of first cards;
sending the first signal to the second card;
receiving, in the checkout computer, second signals from the card in the plurality of first cards;
receiving a third signal from the electromagnetic detector, the third signal corresponding to a product in the store; and
determining a price depending on whether the third signal corresponds to one of the received second signals.
