Abstract
A secure financial messaging unit (906) includes a wide area radio frequency receiver (804), a selective call decoder (1004), a financial transaction processor (1014), a main processor (1006), and a message origination unit (1034). The message origination unit (1034) operates in at least one of a reply and confirmation mode and a originate and request mode to effect a wireless financial transaction using a local area link (924).
Claims39
A secure financial messaging unit, comprising:
- a wide area radio frequency receiver;
- a selective call decoder coupled to the wide area radio frequency receiver;
- a financial transaction processor coupled to the selective call decoder;
- a main processor coupled to the financial transaction processor and the selective call decoder;
- and
- a message origination unit coupled to the main processor, the message origination unit operating in at least one of a reply and confirmation mode and an originate and request mode to effect a wireless financial transaction using a local area link.
In a secure financial messaging unit, a method comprising the steps of:
- receiving a selective call message including a secure financial transaction message, the selective call message being broadcast from a wide area selective call signalling system;
- decoding the selective call message to recover the secure financial transaction message;
- decrypting the secure financial transaction message recovered from the selective call message;
- and
- presenting a message indicating that at least one of a confirmation and an authentication of a financial transaction associated with the secure financial transaction message is requested.
In a secure financial messaging unit, a method comprising the steps of:
- generating a message requesting a financial transaction;
- selecting at least one of a optical, an electromagnetic, and an acoustic transducer in a message origination unit to communicate the message requesting a financial transaction;
- contacting a regulator using a local link between the message origination unit and at least one of a point of sale terminal and an automatic teller machine, the regulator being an authority that governs the financial transaction;
- receiving a selective call message including a response to the message, the selective call message being broadcast from a wide area selective call signalling system;
- decoding the selective call message to recover a secure financial transaction message;
- decrypting the secure financial transaction message recovered from the selective call message;
- and
- presenting a message indicating that at least one of a confirmation and an authentication of the financial transaction associated with the secure financial transaction message is requested.
