Abstract
An access control unit interface between a fingerprint scanner and a host processor is described. A daughter card is coupled between the fingerprint scanner, various access control peripherals, and the host processor. The host processor can be any commercially available processor. The daughter card handles real-time and interactive access control events. The daughter card may include an access control interface processor. The access control interface processor may include a display interface module, a keyboard module, a Wiegand interface module, a finger detect interface module, a LED interface module, and a serial communication module.
