This fall businesses will be able to accept digital ID stored in Apple Wallet to verify customers. This could be used to verify identity or just customer's age. Biometric authentication will be required to access ID.
Starting this fall, businesses will be able to accept IDs in Apple Wallet — no additional hardware needed. This will streamline their ability to securely check a customer’s age in person for things like alcohol purchases, or to verify a customer’s identity at checkout for car rentals, and more. To seamlessly and securely present their ID in Wallet to an enabled business, users simply hold their iPhone or Apple Watch near the business’s iPhone. Users will be shown what information is being requested and whether the receiving party will be storing the information. Users will then be asked to authenticate and consent by using Face ID or Touch ID.Apple Newsroom
