A store system for a commercial system with multiple products. The store system includes multiple register stations. Each register station includes a bar code reader that generates a first signal identifying a product selected by a customer, a register computer, and a cable that transfers the first signal to the register computer. Each register station is associated with a respective second computer that sends a second signal to the register computer. A cable transfers the first signal to the second computer. The register computer includes logic that determines a total amount due from the customer, by receiving the first and second signals. In an exemplary embodiment, the second computer interfaces to a customer card that stores discount information. |
