The EPnet cashless system from Quintus integrates access control and food service payments on one small card.

In hotels, such as the Zetter in London, room cards are programmed so purchases can be made from vending machines, charging costs directly to guests' room bill.

In the workplace, building access devices may also be used to purchase food in the staff restaurant or from vending machines. Cash is never held on the card, but debited from user accounts.

Price: From £5,000 for a small installation
