You could just store the wallet on the NFC already encrypted. Then whatever device you use to read the encrypted data off the NFC, the software on the reading device could then prompt you for the password to decrypt the information and use the wallet.
Seems like there aren't a ton of security benefits to this, unless the NFC chip can sign transactions (offline), which it can't. The above process still results in your unencrypted private key residing, at least in memory, on an internet-connected device for some period of time. Unless the quantities of money involved are trivial, that situation is best avoided.
