This 10% number is a new stat to me. I'd be curious where it comes from.

It is broadly estimated that in the US, only 10% of money in circulation exists in physical form. This means that the majority of our financial transactions are already made electronically – from Google- and Apple Pay to PayPal, Venmo, and debit or credit transfers.

I had a mostly visceral reaction to REAL ID, not having thought about these surface level consequences even.

In the US, the Department of Homeland Security is currently phasing in REAL ID, a 9/11 era program that aims to ensure data consistency across states. In reality, REAL ID is set to revolve around mobile drivers licenses that provide law enforcement with real-time access to a person’s data. As the primary form of identification, a mobile drivers license would enable law enforcement to see whenever a person showed their ID at age-restricted venues and for age-restricted purchases, such as bars or nightclubs.
