Transition and connection device for radio frequency point of sale transaction systems
First Claim
1. A method of data transmission comprising the steps of:
- providing a source of serial data;
providing a packetized data radio frequency communication network;
providing a device to communicate over the packetized data radio frequency communication network;
transmitting data signals from the source of serial data to a modem;
spoofing a land-line modem connection between the device and the modem using a set of predetermined simulation signals; and
transmitting the data signals from the modem through the radio frequency communication network using the device.

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.

7. A system for transmitting transaction requests over either a serial or packetized data network, comprising:
-
means for providing a first serial output data signal containing information pertinent to the transaction; means for determining whether the first serial output data signal is to be transmitted via the serial or the packetized data network, wherein the means for determining comprises; memory means for storing a programmable delay value; and processing means responsive to the programmable delay value and responsive to the first serial output data signal for determining whether the first serial output data signal is to be transmitted via the serial or the packetized data network; converting means responsive to the processing means for converting the first serial output data signal into a first packetized signal if the processing means determines that the first serial output data signal is to be transmitted via the packetized data network; and a transmitter for transmitting the first serial output data signal onto the serial network or for transmitting the first packetized signal onto the packetized data network. - View Dependent Claims (8, 9)

10. A system, for transmitting transaction requests over either a serial or packetized data network, comprising:
-
means for providing a first serial output data signal containing information pertinent to the transaction; means for determining whether said first serial output data signal is to be transmitted via said serial or said packetized data network; means for converting said first serial output data signal into a first packetized signal, wherein said means for converting comprises; a memory for staring a plurality of programmable account numbers for said packetized data network; means for determining whether said first serial output data signal contains one of said programmable account numbers; and means for assembling a packet which further includes said programmable account number and said first serial output data signal for transmission over said packetized data network; and a transmitter for transmitting said first serial output data signal onto said serial network or for transmitting said first packetized signal onto said packetized data network. - View Dependent Claims (11, 12, 13, 14)
