Barclaycard is testing a new payment service that could mean the end to waiting for your bill at a restaurant. It's called Dine & Dash, but in this version, dashing doesn't mean skipping out on your tab. Instead, with this service, restaurant-goers would download the Dine & Dash app and just tap their phone on the Dine & Dash device at their table once they arrive. They would then order their meals and eat as usual, and once they were done, they could just leave. When the Dine & Dash app registers that the diners have left the restaurant, it will check them out and close the bill, issuing payment from whatever payment option was loaded into the app by the diner.
