Abstract
A secure messaging system (900) generates a secure financial transaction message. A wireless selective call signaling system controller (102) receives the secure financial transaction message as a selective call message request including a destination identifier. A selective call message processor (1104) encapsulates the secure financial transaction message in a selective call message that includes a selective call address corresponding with the destination identifier. A selective call transmission service (904) conveys the selective call message to a financial messaging unit (906) that receives the selective call message, and in response to correlating the selective call address with a selective call address corresponding with the financial messaging unit (906), recovers the secure financial transaction message to effect a financial transaction.
