Yeah, then it's appropriate to call this NFC.
- lxgr 2y agoExcept that the highest layers in that stack is not used by many contactless systems. As an analogy, you wouldn't call HTTP or TCP "web protocols" either, even though the web uses both (but it can also run on QUIC, which is UDP, and you can do non-web-things via HTTP). Importantly, NFC standardizes a way of storing structured data like URLs or phone numbers on NFC tags; transit tickets most likely don't use tags in that way.
