ELECTRONIC TRANSACTIONS WITH MOBILE COMMUNICATIONS DEVICES VIA ENCODED ACOUSTIC SIGNALS

摘要

Information is exchanged between a mobile communications device and an automated information system. The mobile communications device is equipped with an acoustic transmitter (speaker) and an acoustic receiver (microphone), and the automated information system is equipped with an acoustic transmitter (speaker) and an acoustic receiver (microphone). The automated information system transmits a first acoustic signal encoded with a first dataset. The mobile communications device receives the first acoustic signal, decodes the first dataset, processes the first dataset, generates a second dataset, encodes the second dataset in a second acoustic signal, and transmits the second acoustic signal. The automated information system receives the second acoustic signal, decodes the second dataset, and processes the second dataset.

主权项

1. A method for exchanging information at a mobile communications device comprising an acoustic receiver and an acoustic transmitter, the method comprising the steps of:
receiving at the acoustic receiver a first acoustic signal encoded with a first dataset; decoding the first acoustic signal to regenerate the first dataset, the first dataset comprising billing information; generating a second dataset based at least in part on the regenerated first dataset, the second dataset comprising payment instructions determined based on the billing information; encoding the second dataset in a second acoustic signal; and transmitting the second acoustic signal from the acoustic transmitter.
