Square has agreed a new partnership with Starbucks Coffee, reports say. Beginning this fall, Square will handle the processing of both credit and debit card transactions at all of Starbucks' 7,000 US locations. Starbucks is also planning to integrate Square Directory into its own apps and network, which could potentially expose Pay with Square users to more merchants. At a minimum, Pay with Square will allow people to find a nearby Starbucks through the Directory.
