Going NFC isn't going to get rid of physical currency. If you look at cities like Seoul, Tokyo, Hong Kong, etc who have widely adopted NFC/mobile payment methods, nothing changed except efficiency.
When I visited Seoul, I bought a bus pass like a total noob tourist. When I was riding the bus to my destination, I saw people just bump their butt or bag next to the machine in the bus and it beeped. They didn't even take out their phone to pay with NFC. That is how much mobile payment methods matured in other countries. They don't think twice about it.
