I would absolutely not.
This is going to have a NFC component that will hand over to whatever merchant you use it your entire DL info. That's not just proof of age, that's your DL number, your SS number if it's on there, your home address, whether you need glasses or not, the kind of DL you have, and anything else on there.
The liquor store clerk does a quick glance at my DL, if they ask at all. Unless they've got a photographic memory, they don't remember the rest.
And for those places that like to scan the barcode - that won't work, because my DL had a brief accident with a bench grinder, the barcode is unscannable.
My DL will NEVER go on my phone. Not happening. I'm sticking with the physical card for that.
