Square will begin processing all credit and debit card transactions at Starbucks stores in the United States

Square will begin processing all credit and debit card transactions at Starbucks stores in the United States:

At first, Starbucks customers will need to show the merchant a bar code on their phones. But when Starbucks uses Square’s full GPS technology, the customer’s phone will automatically notify the store that the customer has entered, and the customer’s name and photo will pop up on the cashier’s screen. The customer will give the merchant his or her name, Starbucks will match the photo and the payment will be complete.
