With the iOS 15 update, Apple Wallet will be able to store driver's licenses just as it does with credit cards and debit codes. The digital copy of your ID will be valid just like the actual license and will be accepted even at TSA checkpoints.
It is worth noting that this feature will be available only to users located in the US states upon its launch.
Your Apple Wallet version of your driver's license will come encrypted and read through digital scanners. The iOS 15 update also adds Apple Wallet support for ID cards, Lock Reader in general, and even hotel keys in participating locations.
In a new partnership with TSA, Apple Wallet will automatically pull the exact information you need at the airport, and have it available on your iPhone in a single scan.
