Are there any BTC debit card options with NFC or QR code capabilities that allow you to transfer directly from a mobile wallet to debit card? Are debit cards able to have a wallet in them even? Or do BTC debit cards convert BTC to USD?
The BTC wallets and conversions take place via the card provider's website or app. There's no such thing as directly tapping the card and magically loading it. You'll probably need to verify with the provider and then you nominate amounts and they have to feed you the address to load.
If you're in the US you can get Bitpay and Coinbase Shift debit cards.
Outside the US debit card options are pretty thin on the ground. The biggest card provider disappeared at the start of the year and there aren't many other options at the moment. There are a few in the EU like Mister Tango or something, but worldwide availability is not great.
