Nearly 5% of total US transactions in coffee giant Starbucks locations are now made through the company’s Mobile Order & Pay service, representing close to 20% of all mobile payments in store.

“In more than 2,700 stores across the US, Mobile Order & Pay represents more than 10% of total transactions at peak,” the company’s Kevin Johnson told investors during Starbucks’ Q3 earnings call. “In several hundred of those US stores, Mobile Order & Pay represents more than 20% of transactions at peak.”

Mobile payments now account for approximately 25% of all transactions taking place at Starbucks’ US locations, up 1% from April 2016.

Mobile Order & Pay was launched across all US locations in September 2015 and was followed by launches in the UK in October and Canada later in the same month.
