For now, I am just going to gather links to good info on NFC. This is the one that made me realize I needed this page. I liked it, and realized I didn't have a home for it. Hence, new page.
Eventually I'll be bored or need to gather the info for a project again (I have worked on NFC and contactless payment, it's just been a few years...) and plan on doing this up much like the Location article above; as a technical intro with design concepts baked in.
