APPARATUS AND METHOD FOR INITIATING A TRANSACTION HAVING ACOUSTIC DATA RECEIVER THAT FILTERS HUMAN VOICE

摘要

In accordance with the present invention, an apparatus initiates a transacti on and includes an acoustic data receiver, and microphone for receiving an audio si gnal having encoded data that is non-discernable by a listener and is transmitted as par t of the audio signal. The microphone converts the sound waves into an electrical signal. A processor receives the electrical signal and retrieves transaction data that is part o f the encoded data. A filter is associated with the microphone and removes a substantial p ortion of a human voice signal that may have been received within the microphone. Once thetransaction data is retrieved, a telephone call can be originated and at least a portion of the transaction data can be transferred to a desired destination for initiat ing a transaction.
