Doutor Coffee Shops added code payment options recently. The sticker next to the reader says all that you need to know: please have your payment app ready before paying. The downfall of code payments is always the network connection. Maybe network connection is weak, or tapped out, or whatever. Last week I was grocery shopping at a basement store location and noticed customers running from checkout to the bottom of the stairs, tapping their smartphone, then running back to the checkout. Bad network area.
This is all too common and a real pain now that every store chain and their dog has a rewards app. Most checkout goes like this: the customer pulls up the store app for discounts and reward points, then pulls up PayPay, dBarai, Line or any other popular code payment, and if the network gods are benevolent, finally pays. NFC was supposed to save us from slow plastic cards and paper coupon checkout, but in the digital wallet age we’re slow if not slower because the store location is in a crappy network area, inside a building with thick earthquake proofed concrete walls. Welcome to code payments in the real world 101.
