Reputable Biometric Fingerprint Scanner & Access/Attendance Solutions? [closed]
Solution 1:
I would recommend the Recogniztion Systems Handpunch units.
We use Handpunch 2000 at work for our Time & Attendance duties for our janitorial staff (large airports, companies etc). I wrote the software using the .NET api (C#). We've got about 10 units running and another 7 on the way. Very stable and no problems/failures for the past few years. I have seen these units being used in data centers for identity verification in man traps and other door locks.
The units are fairly expensive, each unit costs around 1000 bucks but it will give you the option of flexible connection (Modem, Serial, Network, etc.) as well as API in popular languages enabling you to either develop your own solution or purchase one.
