Georgia passed a law over the summer to study the technology and have police accept it by 2 years from then. Montana said their officers should accept it by years end.Already changed in some states? Which? If and when they do, what terminal will an officer bring to the window of your car? Are these states going to issue iphones to all officers to read your wallet?
If the officer is going to carry something to read the apple wallet, better if they have a device that works like Apple Face ID and simply scan your face. That's what TSA pre-check is already piloting at some airports.
Still remains to be seen because they can always delay.
The officer brings a phone. Could also scan a traditional ID card too. One device for both. Phone just needs an app on it that takes NFC read and submits to the back end.
I know about facial recognition at airports, but I don’t know if they have a mobile reader for facial recognition yet. The airport version is like a mini photobooth. Plus some privacy-types are against the government having your biometrics on file.
