Assignee:
GTE Mobile Communications Service Corporation - Houston TX
International Classification:
H04M 1100
US Classification:
379 59
Abstract:
A system (10) for operating a multiplicity of credit card reader-equipped cellular mobile radiotelephones (CMRs 12) as credit card paystations is disclosed. The CMRs (12) incorporate a remotely programmable unit (RPU 48) which controls credit card operation (1400, 1700) and which controls data communication sessions (1800, 1900, 2100) with a credit card (CC) host (26) and a remote programming (RP) host (24). The RPU (48) resides between a conventional control unit (CU 42) and a conventional transmit/receive unit (TRU 62) of a conventional CMR. The RPU (48) monitors messages (1200, 1300) transmitted from the CU (42) and from the TRU (62). The CMR (12) powers up in a locked state (1402), within which a credit card (88) may be read. The credit card is locally validated (1421) at CMR 12. If the validation is successful, the CMR (12) is unlocked so that a call may be placed.
