A restaurant transaction processing system which employs low-cost cordless phone transceivers to transmit orders. A server includes a first cordless telephone transceiver. A portable computer includes a second cordless telephone transceiver and transfers order data to the first computer. The first and second cordless telephone transceivers preferably operate at frequencies designated by the FCC and have a transmission range less than five thousand feet. A typical frequency of operation is in a frequency band near 900 MHz. The system may also include a kitchen terminal which is coupled to the server through a network, and a transaction processing terminal which is also coupled to the server through the network. The server maintains transaction data, routes orders to the kitchen terminal, and routes order ready signals from the kitchen terminal to the portable computer. The transaction processing terminal completes payment for the orders.
