Abstract

A pointing device including a multi-bit data sensor configured to receive multi-bit data from a portable data repository. The multi-bit data sensor may include a transducer configured to read a bar code, characters, a magnetic strip or the like, and generate resulting electronic data. In various embodiments the portable data repository is a credit card, smart card or other data card. The pointing device may further included memory for data storage and a logic circuit for processing of stored data. In typical embodiments the pointing device is a mouse, trackball, or joystick and the multi-bit data is used for user authentication or secure transactions.
