Abstract
A security system using biometric characteristics avoids lost data identifiers and lost physical keys. A biometric scanner, such as a capacitive fingerprint scanner, coupled to the processor of a personal digital assistant or cellular telephone, wirelessly transmits data representing the biometric characteristic using the Bluetooth protocol. By using a well known data communications protocol, such as the Bluetooth protocol, wireless access devices that rely upon biometric characteristics, preclude reliance upon passwords, PIN numbers, keys and other indicia used to establish authorization of a user and can function as universally accepted access keys.
