What is this even for? The convenience of not needing to carry a form of payment? The same article discusses app based payments using NFC as “dethroning cash”, and most people would likely have their phone with them even if they leave their wallet at home. Speeds up check-in time to several seconds instead of 20 seconds? Is that really forming a bottleneck at these restaurants? And what about simply preparing your phone for the QR code or whatnot before you get there? What about wearing masks or large sunglasses that obscure your face; surely removing those would increase the time closer to the eternity that is 20 seconds?
