  • Point of sale system that bypasses the public telephone network
    Patent number: 5541925
    Abstract: A system for communication between a POS terminal and a destination host, which may be a credit transaction authorization entity. The system includes a POS terminal, RF network port, a packet switched network, a destination node, and a destination host. The system eliminates dependence on the public telephone network by using a radio frequency link rather than the public telephone network to access the packet switched network. The originating node assembles a Data packet, which include all necessary transaction data, prior to sending a Call Request packet to the destination node, thus eliminating handshake steps and reducing the duration of packet switched network use.
