To be honest, I think NFC is a bit more accessible to do this kind of
application considering it's in the back of most android/windows smart
phones. You could use a Nexus tablet as the "clock" and have employees use
their smartphones to scan past it. You could also issue small cards with
embedded NFC tags for those employees who don't have smartphones.
