Burger King to Add Mobile-Phone Payment at U.S. Stores

Burger King Worldwide Inc., the second-biggest U.S. burger chain by store count, is introducing an application that will allow customers to pay for Whoppers with their smartphones as it races rivals to woo younger diners.

The program will be introduced next month and should be in all of Burger King’s more than 7,000 U.S. locations in “a few months,” Bryson Thornton, a spokesman for the company, said in an e-mailed statement. The option to order food and drinks ahead of time for later in-store pickup may be added, he said.
