In The Washington Post, Hayley Tsukayama recently wrote about the popular website and mobile app OpenTable's roll out of mobile payments in the article, "Sick of waiting for your check? OpenTable's smartphone app will allow you to pay and leave."Although it has traditionally been known as a place to easily make reservations, search for restaurants and even read reviews, OpenTable is now expanding its capabilities. Tsukayama discusses how this new feature will improve the dining experience, as consumers will no longer have to wait for their check. It also frees up servers' time, as this app alleviates the time consuming responsibility of correctly timing presenting the check to diners. The service, which started in New York and San Francisco, is now rolling out in the DC area. Popular restaurants like Top Chef superstar Bryan Voltaggio's Aggio and Family Meal are participating in the program.
