Abstract
An identification card contains retrievable identification data in at least two formats. One format comprises a magnetic material that stores magnetically encoded data. Another format comprises electronic circuitry that stores electronically encoded data. The magnetically encoded data on the card may be retrieved by inserting the identification card into a reader having magnetic sensors. The electronically encoded data on the card may be transmitted from the card as a radio frequency signal that incorporates the data, to a remote sensor that receives and processes the radio frequency, data encoded signal. A structure for the identification card comprising these two data storage formats as well as a method of producing such an identification card is described.
