Patent ID: 7079810

Claim:
A system for communicating with a remote communication unit via a public switched telephone network (PSTN), comprising: a personal data access device executing a program that is to communicate with the remote communication unit via the PSTN; a first radio frequency (RF) transceiver associated with the personal data access device and in communication with the program, wherein the first RF transceiver is controlled by the program; a public, pay-type telephone, electrically connected for communication over the PSTN; a second RF transceiver interfaced with the telephone, the second RF transceiver configured for communication, via an RF link, with the first RF transceiver; and a controller interfaced with the telephone, responsive to communications received from the first RF transceiver to communicate over a data communication link via the PSTN to the remote communication unit designated by the personal data access device, the controller being configured to allow data communications over the PSTN, the controller and the program being further configured to maintain two-way communication between the personal data access device and the remote communication unit via the PSTN and the RF link, and the controller being further configured to terminate the data communication link over the PSTN to the remote communication unit designated by the personal data access device, wherein responsive to receiving from the first RF transceiver a termination communication that originated from the program, the controller terminates the data communication link.
