For me, it doesn't look good. Why would we even need banknotes when we have smartphones in our pockets which can store our bitcoins securely? There are many well coded wallets for Android and iOS which are fairly easy to use. I understand that some people might have problems with using Bitcoin, but it's not that difficult at all if you are not interested in coin control for example. The number of available bitcoins on the banknote won't change so someone will have to scan it with NFC anyway. It's not really convenient.

There are OpenDime devices on the market already, and they recently seem to have developed a new version of their disposable wallet. One of the use cases stated is a truly anonymous transfer of large amounts of bitcoins totally avoiding any traces that regular transfers leave on the blockchain. For example, you want to buy something expensive and don't want anyone to know about that. You privately exchange this hardware wallet with your bitcoins in it for the thing you are looking for, and that's pretty much all there's to it. If you feel interested, you can search for a thread about these devices somewhere around here started by their developer and read about possible use cases in greater detail there.
