Abstract
On Chip Smart Card verification of a cardholder using biometrics such as a fingerprint and consequent enablement of a card operating system, having an additional software layer boot prior to the commercial card operating system booting. This software layer, or boot loader, provides the drivers and functionality for the finger print sensor and on-card matching. If the cardholder is successfully authenticated, the unmodified commercial OS is then allowed to boot. If the cardholder does not authenticate with the boot loader then the card does not boot the card operating system and thus cannot be used for financial transactions.
