Is there a simple biometric come-and-go system?

Question

Workplace

Hello!
Tell me a simple system for records like: " date - time - start / stop - employee name "?
It can read at least by fingerprint, even by the palm of your hand, etc. - doesn't matter.
Even if the system simply writes to a text file or sends an email, this will already be enough to effectively account for our working time. You just need to know who arrived at what time and who left at what time - in general, this is all that is needed. I will be glad to any tip!
Sincerely.

We use Biosmart readers . For your tasks, their standard software should be enough, we wrote a web interface for ourselves.
