Single point of failure anyone?
I find this whole push of digital phone based id cards, drivers licenses etc to be mostly stupid. I'm out traveling, ohh my phone died since it's not charged no id or license (unless you have a classic one as backup with you), you are off somewhere your phone charged and ready, it drops and the screen dies, no id, and people say ohh you could lose your wallet with cards and id in it, yes you could, but I bet that if you ask 100 people how many times they have lost their wallets and how many times their phone have been without charge or damaged I'm sure the latter part would dwarf the former. I'm also against concentrating more and more vital things to one single vulnerable point of failure. Having digital as a compliment, fine, but it's not in any way shape or form a replacement.
