Why add ID to Apple Wallet?
Your ID in Apple Wallet is more secure than carrying around a physical card that could be lost or could reveal personal information to someone you may not wish to have it.
Digital IDs in Apple Wallet do not display any personal information other than your name. If you tap the (i) button to get more info, and then tap Driver’s License Info, your iPhone requires a Face ID or Touch ID login to see things like your address, date of birth, height, eye color, ID number, and so on.
The transaction starts over NFC and negotiates a secure Bluetooth LE session—no barcodes. So, you never have to hand your phone over to a police officer, TSA agent, or anyone else, and even if you do, they can’t get your personal info without your authentication.
Using your digital ID works a lot like Apple Pay. You hold your iPhone near the reader (which may be another iPhone), and a screen will pop up saying exactly which information you’re going to share. Double-tap the side button to approve it, just like approving a payment.
