Having traveled in Europe and most recently, in Mexico, I was impressed by the fact that most restaurants I frequented use table-side credit card authorization terminals, irrespective of type or level of service and price points. These devices enable the restaurant guest to pay by credit card or debit card, either by inserting a card into a mobile device or contactlessly. The card never leaves the customer. In the U.S., these devices are now starting to become more widespread, but have yet to approach critical mass.
