Abstract

A credit card size authentication card is manufactured using innovative sensor technology, processor technology, power generation and storage, panel display and integration technology. The front of the card has a data display and an exposed, biometric sensor. Internally the card has one or more flex boards that carry low profile, surface-mounted electronic components including a processor that provides the control functions and mathematical calculations to generate a series of random personal identification numbers (PINs) in the display. The random PINs are derived from a biometric seed number obtained during initialization of the card by a discrete user. The electronic circuitry controlling and interconnecting the processor, the sensor and the display is powered by a power system including a thin film battery, a thin film power generator and a low profile power regulator. The thin film power generator preferably comprises a thin film solar collector or RF antenna circuit for energy harvesting. The thin film power generator and thin film battery are layered and preferably docked to the flex board carrying the primary components of the card. The card panels are formed from panel sheets which may be reverse printed with the top or front panel sheets having clear or translucent windows for the data display and solar collectors and die cut to expose the sensor elements.
