So I live in the UK, and they’re talking about moving to a digital ID scheme. My resident permit is already digital, so when I enter the country I need to, if I get stopped, access the government site, generate a share-code, provide it. With the proposed digital ID it would be like your G-Pay or ApplePay bank/credit cards, your driver’s license would be in your phone’s “wallet,” or a separate app. I would have no choice but to hand my powers on phone to an officer. There’s some things that can be done, on modern android you can pin a page so when you hand over your phone the only thing that can be accessed is the pinned thing. Phone needs to be unlocked to get at anything else, but it’ll still accept biometrics.
