Maybe 1-Wire "ibuttons" from Maxim (used to be Dallas, I think).
A bit of an introduction here:
https://www.maximintegrated.com/en/products/ibutton/ibuttons/index.cfm
Waiting staff in bars & restaurants often use them to log themselves
into
the till.
It's been ages since I looked at them so not sure about pricing, etc.
HTH,
Tim.
