Does anybody really want this? I do not want to carry my license in my phone and then need to hand my phone over to stranger and even worse a police officer while I sit in my car phoneless and he is doing who knows what with it.
I'm not quite the target for this, but I'd value the ability to take age-ID (which for me is always my driving license) on my phone in some way.
I'll also say that I think you can get to Samsung wallet without unlocking your phone, though you need to authenticate to trigger payment, so it's possibly a way of not handing your unlocked device out.
I'm always weirded out by folk handing over cards to be taken to machines in other areas, too.
I think they don't take your phone, just scan it. I don't know how it works with this, but I have a trial for my state's digital ID app (the app works but isn't fully implemented as a complete replacement for physical IDs yet), and it has two modes I can put it in which generates a QR code on the screen with my data. One mode for police to scan at traffic stops which has my driver's license info, and one just called "age verification" which can be presented when buying alcohol which just verifies that I'm over 21. I like the privacy of the second mode, since there's no reason a liquor store needs to be able to see my home address.
These should, instead, be implemented by NFC. You tap their "reader" with your phone, never surrendering it, and they get your ID number just like a merchant gets your CC info for a charge. Their backend pulls up your record just as if they'd scanned the qr code on the back of your physical card. Or you can locally transmit a facsimile image to a promiscuous reader (airdrop/nearby share) you approve.
I don't even get what the point is. No ID should be valid identification without some form of biometrics validation performed on the spot, each time, every time. Otherwise anybody can just steal your ID and go around pretending to be you.
If they're counting on the phone being unlocked by biometrics that's completely circumstantial since there may be no relation between the unlock biometrics and the id biometrics.
