The article states exactly where it can be used right now. Which is just with TSA for now.A feature that is 100% useless as based on my experience, no agency, no business or no one accepts it as a proper ID.
I literally use it as my ID for getting through TSA. It works like ApplePay or a “Tap-to-Pay” NFC transaction. Your phone stays locked, you 100% keep possession of your phone, it doesn’t get handed to anyone, there is just a little plastic protrusion in front of the TSA agents booth that you hold your iPhone over.
Instead of bringing up a credit card — it bring up your digital ID. It shows you that it’s the TSA you’ll be presenting it to and lists out exactly the details which will be presented. If you agree, you double tap your sleep/wake button (just like an apple pay transaction) to transmit / present the digital ID. I specifically choose to opt-out out of and do not let them do the Photo ID biometric match, and they still let me through.
It’s like early days of Tap-to-Pay. It’s not really that much faster and, in the past, if the cashier you got was unfamiliar with Tap-to-Pay it could be slower because you need to educate them just a touch. But, these days now, I don’t think anyone that knows of “tap-to-pay” actively rejects using it, unless some particular credit card gives you more “points”, a statement credit, or more “% back” in a specific catagory.
