> So this is only valid for TSA or for traffic stops as well?

According to TSA, it is not valid for TSA:

However, TSA did issue an RFI earlier this year in preparation for rulemaking which could authorize this kind of application:

That’s currently the case; the feature isn’t even out yet.

Can you imagine willingly handing your phone to a cop?

> Presenting a driver’s license or state ID to TSA: Once added to Wallet, customers can present their driver’s license or state ID to the TSA by simply tapping their iPhone or Apple Watch at the identity reader. Upon tapping their iPhone or Apple Watch, customers will see a prompt on their device displaying the specific information being requested by the TSA. Only after authorizing with Face ID or Touch ID is the requested identity information released from their device, which ensures that just the required information is shared and only the person who added the driver’s license or state ID to the device can present it. Users do not need to unlock, show, or hand over their device to present their ID.

Please read the article. It's presented there, and not even hidden away.

TSA aren't cops. I was referring to a traffic stop, where the default order from a cop when presented with something like this would be simply "give me your phone."

If the cop doesn't have a reader that can read this on his belt, he is not going to accept it anyway, just like they wouldn't accept a photo of an ID. They'd require the physical license.

If he has a reader on his belt, you would still not need to hand over the phone, you would just tap it on his reader, which would then prompt you to agree to share the specific fields from the driver license that he needs.

I mean yeah, of course they could still demand your phone, they can also demand you get out of the car, handcuff you, search the car and take anything they find on the most vaguely worded suspicions, but there's no technical solution for that problem.

Yes, they should verify the information with their reader. But many wouldn't. I'm Ukrainian, we've got a government app called Дія, that contains a digital copy of ID card, driver's license and some other documents. The document is presented in text+photo form (which is obviously easy to fake) and in form of a QR code that has a TTL of 3 minutes. Police is supposed to scan the QR code with the same app on their phone and that will load a copy of the document from government server, which is a way to properly verify the document. Still, on my last interaction with police, they just took a picture of my phone screen. It would take a bit of time to train all personnel on using digital documents.

Imagine trusting Apple.
