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.

Claims

1. A method for dual use of radio communication and telephone communication for evaluating a transaction request that includes the transmission and verification of coded data comprising the steps of:

a) obtaining one or more external encoded data signals containing information from at least one encoded data signal source to evaluate the transaction request;

b) determining from said external encoded data signals whether the transaction request is to be performed through use of a radio frequency data communication network or a telephone communication network; and

c) transmitting the information contained in said external encoded data signals either by radio communication or telephone communication according to the results of said determining step.

3. The method of claim 1, wherein said determining step further comprises the steps of:

a) generating a destination code that includes the telephone number of a transaction authorization center and one or more additional telephone compatible data characters; and

b) monitoring said destination code for the presence of said telephone compatible data characters signifying whether evaluation and authorization of the transaction request is to be accomplished through radio communication or telephone communication.

4. The method of claim 3, wherein said destination code includes a data communication identification number, designating either radio communication or telephone communication, set off between delimiter characters.

5. The method of claim 3, wherein said destination code includes a delay character designating either radio communication or telephone communication.

6. The method of claim 1, wherein the determining step is accomplished through use of a preprogrammed point of sale credit card reader.

7. The method of claim 3, wherein the generation of said destination code is accomplished through use of a preprogrammed point of sale credit card reader.

2. A system for transmission and reception of transaction data including the transmission and verification of coded data over at least one of a plurality of communication networks comprising:

a) at least one encoded data signal source providing at least a portion of said transaction data;

b) a translation and connection device comprising means for combining, processing, and emitting information received from each encoded data signal source and further comprising means for processing a transaction in accordance with said transaction data and an authorization signal, said translation and connection device determining from at least a portion of said information received from each encoded data signal source, which of the plurality of communication networks is to be used to process the transaction; and

c) a host device operatively connected by radio communication to said translation and connection device for receiving and interpreting said transaction data and for transmitting said authorization signal to said translation and connection device.
