PayPal's mobile payments have been on a whirlwind American tour this year, but they haven't had a chance to cross the border so far. Someone must have finally stamped the company's passport, since it's now an option for UK residents to pay using the InStore app for Android or iOS. A trio of fashion outlets -- Coast, Oasis and Warehouse -- can soon scan an on-screen barcode to take payment for that posh new shirt instead of requiring ye olde wallet. As it is in the US, there's no need for any NFC magic or even an Internet connection to clinch the deal, and there's still the same access to discounts and refunds as for paper- and plastic-wielding buyers. A total of 230 shops will take your PayPal credit starting May 31st, although they won't stop your potential fashion mistakes.
