Why does nunchuck put QR scan key as air gapped but NFC not?

Is NFC less safe than QR? Is NFC not air gapped? What is air gapped anyway?

I really want coldcard MK4 but now thinking of getting keystone due to what I'm seeing on nunchuck..

Please coldcard fans enlighten me

The ColdCard NFC is super sensitive I don’t believe it transfers much data at all. Minimal.

I don’t see it being a threat.

I personally signed a transaction today via Nunchuk / CC MK4

It’s only a max ~800 bytes and that’s pushing it

Future will fix the bandwidth

Yeah. Perhaps I'm just overthinking due to how nunchuck not putting adding coldcard key under the air gapped definition..

Thanks guys
