I've been wallet free for some years now. Even the driver's license has become an app here in Norway (optional, you still get the physical one).
The big downside is that my wallet and everything in it can run out of battery. That's not very redundant. Suddenly I won't be able to pay, identify, call, etc.
How do you show your driver's license to a government official without exposing everything else on your phone, especially to the police? From a US perspective, using one's phone as an ID seems incredibly risky.
You have to carry a licence when driving here in NZ but in the 10-15 years I haven’t carried a wallet I haven’t carried it. I’m not 100% on how it will go if I need it while driving (potential US$200 fine). It’s not needed for domestic flights or anything really.
