there’s a little sticker on the every TechEd 205 badge and they say it’s an experiment/demonstration for the keynote which is going to take place tomorrow. Infact the paper I’ve got with the badge said that there is indeed an RFID device embedded into the sticker. That device holds a random number (approx. the one printed on the sticker). The deal is that there seems to be a demonstration how the people are coming into the keynote hall…some kind of monitoring – probably a demonstration that modern RFID technology doesn’t surrender when 6000+ RFIDs are going to enter the same room.
of course I’ve taken a closer look:
Nothing really new or interesting. Anyone that knows something about those tags?
