“I got to talk with Apple about this today, and I’m impressed.”
A few important details:
Driver’s licenses and state IDs in Wallet are only presented digitally through encrypted communication directly between the device and the identity reader, so users do not need to unlock, show, or hand over their device.
This is a super key point. Of course no one wants to hand over their phone to anyone. More importantly, no one should ever hand their phone to a police officer, and that goes a hundredfold if it’s unlocked. The Wallet system Apple has designed for ID is very much like Apple Pay. When you pay with a physical credit card, you often hand your card to an employee. When you pay with Apple Pay, you never hand your phone to an employee. It wouldn’t even work, because no one else can authorize an Apple Pay transaction without your biometric authentication. This ID feature for Wallet is exactly like that: it doesn’t work without your biometric authentication, and your phone does not unlock when you use it.
An interesting sidenote: when using a Touch ID iPhone with Apple Wallet’s ID feature, you must register one and only one finger when you add your ID to your Wallet, and whenever you verify your ID in Wallet, you’ll need to use that same finger. Apple has never recommended allowing your spouse or partner to register one of their fingers on your iPhone, but many people do that. This feature is designed to ensure that the same person who enrolled their state ID in Wallet is the same person verifying it biometrically. (This is not an issue with Face ID, obviously.)
To use your ID in Wallet, you tap your phone (or watch) against an NFC terminal, and you get an Apple Pay-like sheet showing you who is asking for your ID (e.g., TSA), and exactly which details from your ID they’re asking for (e.g., name, photo, date of birth — but perhaps not other embedded details like your blood type or your home address). So if you’re just buying booze, say, and the clerk or server needs to check your age, they could prompt only to verify that you’re 21 or older, without even seeing your exact birthdate, let alone any other details from your ID. It is exceedingly more private than handing over a physical ID card, perhaps even more so than using Apple Pay compared to handing over a physical credit card.
My take: I’m always amazed when friends who carry iPhones tell me they don’t use — or even know much about — Apple Pay. This might get them off their butts.
