“Customers of US coffee chain Dunkin’ in California will soon be able to walk into a store, pick up a coffee and pay for it from their mobile phone without having to pre-order, interact with staff, wait to pay at a checkout or scan goods at a kiosk. The chain is to pilot the checkout-free contactless retail solution at one of its California outlets from October using Mastercard’s Shop Anywhere automated self-service platform, which uses computer vision technology developed by Accel Robotics to track customers’ purchases while they’re in store.”
