Abstract:
PROBLEM TO BE SOLVED: To provide a selective call signaling system allowing a safe financial transaction by a wireless network by use of a portable financial messaging unit. SOLUTION: A secure messaging system includes a secure messaging system controller and a first financial messaging unit 906. A user initiates a financial transaction by providing a transaction authentication code to the secure messaging system controller. In response to the first financial messaging unit 906 receiving a secure financial transaction message containing a value, a user inputs the corresponding transaction authentication code that releases and disburses at least a portion of the value to the first financial messaging unit 906 for effecting a financial transaction.

Abstract:
PROBLEM TO BE SOLVED: To provide a wireless messaging system that allows an originator to communicate a secure message between a subscriber unit and the originator, and authenticate the secure message without exposing contents or meaning of the message. SOLUTION: A wireless selective call signaling system controller receives a secure financial transaction message as a selective call message request including a destination identifier. A selective call message processor encapsulates the secure financial transaction message in a selective call message that includes a selective call address corresponding to the destination identifier. A selective call transmission service conveys the selective call message to a financial messaging unit, which receives the selective call message, and in response to correlating the selective call address with a selective call address corresponding to the financial messaging unit, recovers the secure financial transaction message to effect a financial transaction.

Abstract:
A portable secure financial messaging unit (906) includes a receiver (804) and a selective call decoder (1004). The selective call decoder (1004) has a memory (1010) that includes a single unique selective call address corresponding with a predetermined financial transaction type. An address correlator (830) operates to determine substantial coincidence between the single unique selective call address and a received selective call address corresponding with the predetermined financial transaction type. In response to a coincidence, a main processor (1006) and a financial transaction processor (1004) process received information to effect a financial transaction corresponding with the predetermined financial transaction type.
Abstract:
A wireless communication system includes a pager or similar device that communicates to a home terminal. The home terminal confirms the identity of the pager and attaches a certificate to the message for ongoing transmission. Where the recipient is also a pager, an associated home terminal verifies the transmission and forwards it in a trusted manner without the certificate to the recipient.
Abstract:
A selective call receiver (100) capable of receiving an energy source (101) having a first supply voltage (506) generates a second supply voltage (507) from the energy source and a third supply voltage (508) from the second supply voltage. The second supply voltage (507) is used to power at least an information display (209), and the third supply voltage (508) is used to power at least one frequency determining element (204).
Abstract:
An inductorless quadrature demodulator for frequency modulated signals. A limited FM signal is passed through an active filter (26) and a phase shift network (30) to produce a quadrature signal. The limited FM signal is compared with the quadrature signal in an EXCLUSIVE OR gate (24) and then low pass filtered (36) to obtain recovered audio. The active filter (26) includes a transconductance amplifier (60) whose center frequency can be adjusted by appropriate adjustment of the amplifier's bias current. The bias current is temperature compensated to allow operation of the demodulator over a wide temperature range.
Abstract:
A selective call receiver (100) comprising a receiver (103), a controller (105), and means for presenting a recovered source document (113). The receiver (100) provides a received paging message that was generated from the facsimile message of the original source document, then the received paging message comprising at least one portion of the original source document and an address is interpreted and decoded by the controller. Using the means for presenting (113), the recovered source document can be exhibited in a format that substantially resembles the facsimile message of the original source document.
