Wow.
Thanks for posting... That's absolutely epic - probably the most polished Espruino project I think I've ever seen!
I really ought to improve the PN532 module so you can read NFC card data with it. I guess you could potentially even read a URL or JSON... However there's a lot to be said for just tweaking a JSON file on a PC rather than trying to write NFC card contents :)
