Contactless Payments

Paying with your mobile phone, just by holding it to the credit card machine, is old hat by now, but do that by tapping your credit card is likely to startle your server.  At least that's been my experience with several servers at Panera Bread. They start to correct me when I put my card on the machine, only to find the transaction is done.  Look for the symbol below on one of your cards and give it a try.
