Bank of America is testing a new mobile-payment service that lets customers use their Apple or Google smartphones to scan pictures to pay for things.The bank is testing technology developed by a company called Paydiant. The solution uses Quick Response or QR codes. The way it works is that users use their smartphones to scan the QR code, which unlocks the users' bank information stored in Bank of America's network to complete the transaction.The QR codes could be displayed at the register in a store when a customer is checking out, or a restaurant could print the code on the check, allowing patrons to scan their bills right at the table and pay without ever handing over a credit card or cash.
