Starbucks processes nearly 9m mobile payments each week, accounting for 20 per cent of its in-store transactions.

This was announced as the coffee chain reported a record $4.9bn (£3.2bn) revenues for Q3. On the companys earning call, Starbucks president and CEO Howard Schulz put this success down to a willingness to invest in technology.

“Many traditional retailers and consumer brands have responded simply by substantially increasing their digital advertising budgets, significantly driving up their cost of customer acquisition and producing little to show for it,” he said. “We, on the other hand, took a very different approach. By further enhancing our already world-class digital technologies through the introduction of capabilities like Mobile Order & Pay and soon to be delivery and expanding our loyalty program, we are driving traffic.”

Mobile Order & Pay is currently operated in over 4,000 Starbucks locations in the US, and Schulz announced the capability would be rolled out “across the entire US company operated store portfolio in time for the upcoming important holiday season”.

Starbucks is also planning to expand Mobile Order & Pay internationally in the months ahead, and to bring the feature to its Android app for the first time.
