I stumbled upon an article in PopSci (Popular Science?) on-line publication titled Everything You Need to Know About Near Field Communication. My opinion is that many of the things described there reflect a lot of wishful thinking on the part of the smart card industry players. Especially where they go on about “everything has just started to come together”, which is exactly the same thing they were saying for the last five years or so. I was on the inside, I should know.
I think that for the more inclined to actually understand the technology in easy words, I would suggest simply reading the original NFC White Paper written by myself years ago and published by Ecma International. Trust me, nothing much has changed in the meantime, all concepts still apply today as they applied then.
