Tap-to-pay could get more capable and more complicated

At some point in the future, a new “Multi-Purpose Tap” concept will let payment cards or devices like smartwatches and phones accomplish multiple things at once when using NFC. With this in play, a customer in a store might tap their phone with Apple Wallet or Google Pay on a terminal that simultaneously checks their ID if they’re buying booze, add points to their loyalty account, pay for their goods, and provide them with a digital receipt.
