Abstract
A device is provided that interfaces with existing point of sale credit card reading devices, and furnishes the option of transmitting data over either the existing modem installation or a radio frequency data communication network. The device scans the information encoded on the credit card to determine which data transmission path is appropriate for a particular transaction. The device software generates the necessary signals to simulate the normal interaction between the POS cardreader device and a modem. The software also converts between serial and packetized data in order to request and receive credit card purchase authorizations over the radio frequency data communication network.
