QR codes vs NFC in Bitcoin Wallets

[tjtonmoy]

QR code is the safest way to do it, I guess. NFC has some flaws, and it's being new, I think in the future this will be improved. But for now until that happens, i think using QR codes will be the best option.
All you need is a camera which will scan the code. But for NFC it needs something extra and those devices which doesn't support NFC will no longer be able to work. So until people come up with something new, QR codes will be used mostly.
