Starbucks UK & Ireland has launched a one-touch mobile payment app for iPhone and iPod users across its 700 stores after a successful roll out in the UK. The chain said it would be the first on the high street to offer UK and Ireland customers the option to pay with one touch using their iPhone or iPod touch. It said the move was a response to increased customer demand to be served quickly using more convenient payment methods. Starbucks said it had found that one in five customers is now happy to buy a cup of coffee with a card. Launched in early 2011 in nearly 6,800 US Starbucks stores, more than 20 million mobile payment transactions have been processed to date. The group said that from the 5 January next year, customers who have a registered Starbucks Card will be able to link the app to their card balance and make payments for their in-store purchases by scanning their unique barcode at the till. Brian Waring, vice president of marketing & category for Starbucks UK and Ireland said: “Customers want to be served quickly, but fewer want to use cash. We wanted to find a way for them to pay in the quickest way possible. Because our customers want it, we have created our own custom-built mobile payment technology rather than waiting for the near field communication technology which is currently not widely available. We’re always thinking of new ways to add value to our customers and give them more reasons to choose Starbucks.” Technology expert Stuart Miles of Pocket-lint.com said: “Cash is set to make up less than half of all transactions in just five years’ time. We are seeing a trend where retail customers want to be served quickly, but fewer want to use cash. Mobile payment technology enables this and for that reason is set to be the future of shopping.”
