I’m not sure how it works for Apple wallet but if your state has digital ID the police scan a QR code on your screen, so they don’t actually physically touch your phone. I just looked at my digital ID and it actually says…share your info scan QR code( and my camera comes up)So maybe you use your phone to scan a QR code that then somehow sends your information to a device the officer has🤷🏼‍♀️
