Contactless refers to the fact that it is a wireless device. A payment is contactless when you don’t swipe or insert your credit or debit card at the checkout. Instead, you just hold your card up to 10 centimeters away from the payment reader at the register and your payment information is sent wirelessly and processed. This is a faster and more convenient way to pay. Many retailers accept contactless payment including Dairy Queen, Walgreen's, McDonalds, CVS and Arby's.
