Mobile payments account for 11% of Starbucks' US sales

"Starbucks, the coffee chain with more than 28,000 locations worldwide, said its mobile order and pay service grew to 11% of transactions in U.S. company-operated stores in Q1 2018 from 10% in the prior quarter. The Starbucks Rewards loyalty program helped to drive mobile growth with an 11% membership gain to 14.2 million from the prior year. Member spending made up 37% of U.S. sales.
The company, which now has the ability to offer mobile order and pay to customers who don’t belong to its loyalty program, plans to ramp up the service to all customers in March, company president and CEO Kevin Johnson said in a conference call with investors. The growing popularity of mobile payment is leading the company to test cashless stores in the U.S."
