The main point I'm trying to make is essentially targeted at this line of logic:

> NFC's design principles inherently prioritize secure exchanges

NFC's design principles inherently has absolutely zero security. It doesn't prioritize secure exchanges, at all. The fact secure exchanges can happen over NFC in incidental to NFC existing. Any secure exchange that happens over NFC happens because the higher-level application brought its own security.

It's like UDP. Sure, you can do a secure exchange of data using it like QUIC or encrypted RTP, but UDP doesn't give you anything other than a way to send that data along.

Which then compared to just an overall massively wide topic like "RFID", which encompasses dozens (hundreds?) of other technologies, some of which do actually prioritize secure (or at least attempted to secure) handshakes throughout the entire stack.

And range of an RF thing is largely just based around typical hardware. If you wanted to you could build an antenna array to pick up an NFC tag from dozens of meters away. WiFi might only be designed to work around the house, but with a clear line of sight, decent RF conditions, and the right antennas you can send it miles.

Generally speaking, you shouldn't expect any kind of security doing things with NFC. Because, NFC has no security inherent to the protocol.
