Good concept I guess? The challenge is to make them easy and quick to transact. The problem with this is that before you actually accept the "banknotes" you need to scan them one by one to confirm that it actually does contain some btc.
Correct me if there's something I missed.
Yes that's very true! It will be interesting to see how they deal with that. It's funny that now the technology is being used to go backwards, from digital to paper (even though it's digital paper). Great concept though!
