Starbucks Korea is expanding a cash-free store initiative to 100 locations across the country, including 74 in Seoul and 11 in Gyeonggi Province. 

For the past few months, it has only been accepting credit card and mobile payments in three locations. It claims that, during this time, the ratio of cash transactions fell from 3% to 0.2% and the amount of time customers spent at the checkouts was cut from ten minutes to three minutes on average. 

Roll-out to the further 100 locations will start on 16th July. Cash transactions at Starbucks stores in Korea now only account for at 7% of all payments, the company says.
