Abstract
A satellite wide area communications network (10) includes a remote transmitter/receiver (28A) that is coupled through a modem unit (30A) to multiple card readers (12A-1 to 12A-n). A master transmitter/receiver (26) is satellite linked to the remote transmitter/receiver and is coupled through a central packet network (16) to multiple host computers (18-1 to 18-j). A network host computer address is determined for each transaction card inserted in the card readers, and the network address is processed to establish a direct link to the host computer for the card through the modem unit, the satellite link (22A, 20, 24), and the central packet network.
