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.
Claims31
an access control unit, comprising:
- a fingerprint scanner;
- a host processor;
- and
- a daughter card coupled between the fingerprint scanner and the host processor;
- wherein said daughter card and host processor are configured in a stacked configuration;

- and
- wheren said daughter card transmits said received fingerprint image data to said host processor, wherein the host processor can be any commercially available processor;
- wherein said daughter card further comprises
- an access control interface processor;
- and
- wherein said access control interface processor receives instructions from said host processor and transmits responses to said host processor;
- and
- wherein said access control interface processor comprises;
- a display interface;
- a keyboard module;
- a Wiegand interface module;
- a finger detect interface module;
- an indicator interface module;
- and
- a serial communication module.
An access control interface processor comprising:

- and
- wherein said access control interface processor receives instructions from said host processor and transmits responses to said host processor;
- wherein said access control interface processor comprises
- a display interface;
- a keyboard module;
- a Wiegand interface module;
- a finger detect interface module;
- an indicator interface module;
- and
- a serial communication module;
- said method comprising the steps of:
