We already have paper wallets, actually. That used to be really popular.

And you can print Lightning eCash on paper.
ok, i will look into eCash.
i think what i'm looking for is just dollar bills/local currency for now. but fast forward 10 years, and it will be interesting to see how it's done because I really don't want to carry around a phone in the future.
Yeh ... physical bitcoin cash notes would be handy
yeah, how would they look... would they have some little RFID circuits printed under the surface to match it with database at the bank that issued them. authenticity could be verified with a phone NFC(API to regulated portal that checks serial number against banks issued paper and BTC holdings) . ownership is just whose hand is holding it.
