A wireless wide area communication system (150) comprises at least one electronic fund transfer/point-of-sale (EFT/POS) device (152) generating an EFT/POS financial transaction data message in response to a financial transaction request. A wireless communications converter (154) in communication with the at least one EFT/POS device receives the EFT/POS financial transaction data message. The wireless communications converter converts the EFT/POS financial transaction data message into a form suitable for transmission over a radio frequency wireless wide area network (wireless WAN) (156). The wireless WAN is connected to at least one financial institution (160) by way of a gateway (158) and a land line connection (162) and conveys the EFT/POS financial transaction data message received from the wireless communications converter to the at least one financial institution. |
