Starbucks has partnered with mobile-payment start-up Square and will invest $25 million in the company. Starting this fall, Starbucks locations in the US will process all debit and credit card transactions with Square. Consumers will also be able to pay for their caffeine fix by showing a Square barcode with the “Pay With Square” smartphone app. The deal will help Starbucks reduce the credit card processing fees it pays to banks.
