Method for conducting financial transactions utilizing infrared data communications
First Claim
1. A method of conducting a transaction comprising:
- placing a mobile first electronic device in infrared data communication with a second electronic device wherein both the first electronic device and the second electronic device have a common encryption algorithm;
communicating a transaction request from said second electronic device to said first electronic device wherein said transaction request includes an encryption key for use with said encryption algorithm;
communicating response data from said first electronic device to said second electronic device wherein said response data is encrypted with the encryption key; and
obtaining payment for the transaction from an account identified from said response data.

Abstract
A method and device are described for conducting a transaction between electronic devices in which transaction data is exchanged over an infrared frequency. A first and second electronic device, with a common encryption algorithm deployed on each device, establish an infrared communications link. The second electronic device transmits a transaction request together with an encryption key to the first electronic device. The first electronic device returns response data to the second electronic device which response data is encrypted using the common encryption algorithm and the encryption key. An account to be utilized in the transaction is derived from the response data allowing the transaction to be completed.
