@BDub - you're a champion - thanks very much for this. I'm currently out of the country, so seperated from my beloved sparkcore - when I am back, I will be testing it and let you know.
@mohit - Sounds like an interesting project - quick question though - what is the need for a shield when the PN532 interfaces on UART/SPI/I2C ? Just for the sake of cleanliness - or did I miss something?
In any case, excited to see NFC making it to the sparkcore, it's really a killer combination for remote access projects.
