Waiter Key which Methode?

Hi! Thanks for such a perfect Programm. For me, I Need a solution to use Waiter Keys for the Waiters. Is it possible to use that for Login and Logout ? Like a magnetic key or rfid? Which Systems have been approved to work for that? Thanks for your answers, greetings from Austria

Any USB RFID reader should work.
I use these as they also have a card swipe http://m.ebay.com.au/itm/171319348265?nav=SEARCH

RFID uses hex encoded id’s, whereas SambaPOS uses only numeric logins. But most RFID tags will have enough numbers in the id to be unique.
