The problems that a digital license solve always seemed so pointless. They seem to come in two flavours: * I want to compress every aspect of my essence onto my phone. These are the people who will kvetch if you don't accept Apple Pay because they haven't touched a physical Mastercard in years. They can't bear to possibly have TWO things in their pants pockets at once. Good for you, kid. Your aesthetic choices are not my government mandate. * I want some means to supply filtered data-- switch the license into a mode that only says I'm 21, no home address or card number. In practice, no non-toy use case will permit it. Law enforcement will demand to see every field either because they don't know how to use the filtering, or see opportunities for fishing expeditions. Age-verification software at the bar that scans the license will inevitably be extended to plumb the data into a CRM, and thus will demand every field on the license. In exchange I get something that runs out of battery, won't survive wading through a flood, and leads to frustrating exchanges with law enforcement who already can't identify most of the 82,000 different types of valid identity document in circulation.
