I have a ACS ACR122U NFC Reader / Writer when i hover over the reader with my Samsung s7. The led becomes green so the reader understands the mobile.

The idea is when a employee comes to work he hover over the reader he gets clocked in.

On github i found some solutions for reading the nfc with python:

Maybe i don't understand it right but shouldn't i get a ID of the phone or able to write data to it or is it just a reader (but why does file transfer works over nfc)?

Maybe i just need to buy a nfc-tag and use that for the clocking?

You could emulate a card on Phone, but you need to install an app on each phone to put it in HCE Host Card Emulation mode. After you NFC reader could communicate with phone.

Easiest solution is to buy tags with unique ID.
