I'm in search for a finger print reader/TimeAndAttendance terminal that does internal fingerprint matching with pre enrolled fingerprint templates and also preferably have the ability to store lets say the last 1000 authentication events.

Such devices do exist, some even run Linux, but for the life of me I can't find any that would enable me to extract logs from it through Serial or Network connection with Linux.

All APIs to communicate are for Windows only and no company can/want to provide me the lower comms. protocol definition that is used in serial and/or network communication, so I can not even write my own API.

Anyone able to point me to a open protocol / Linux friendly T&A fingerprint terminal ?
 
The software to interpret the print will be proprietary and run on Windows...which is why they won't give you the API...because there is nothing to API until the prop software running on windows crunched the data. So your best bet is to find software that will let you grab the info that was stored by the prop software. I very much doubt that you'll find a terminal with built in processing. Might be wrong though...not my field.

Also 1k sounds way to low. Once the system has crunched the raw data its just a unique ID so it should be able to save a billion.

Print matching can definitely happen in the hardware, these devices have nice DSPs in them that does the matching now days. This was the reason for looking for such devices to make it a non issue driver wise. Did the same exercises about 10 years ago and then the matching had to happen on the (Windows) PC.

Finger print embedded modules are also available that can talk serial (with protocol available) but one would then have to build a whole terminal around it (ex. LCD, Keypad, micro-controller for glue logic and enclosure) .... nobody got time for that ;-)
