While a lot of you are going to go full conspiracy theory stuff, and pretend lawyers, I am going to enjoy carrying less stuff with me, since I take public transportation. For days I am driving, I can either a) keep a physical ID in the car or b) have the officer write down the numbers which they have already done for me in the existing Arizona Mobile ID app. I have never had an issue. For the record, I fall in the category of "not Caucasian" and have never had an issue with this mobile ID app and police officers, and I am sure the Apple one will be just the same. Never have I had an officer ask to see the phone itself, and I got pulled over for my illegal tint....got a warning instead and we chatted about the mobile ID app! Ha!
