One of the many interesting things going on at TechEd this year was each attendee was provided a Radio Frequency Identification device (RFID) with their name badge during registration. Here is RFIDJournal site to read more about RFID or simply google on RFID. The device didn’t contain any personal information not was it linked in any way to registration but was used as a way to participate in two of the TechEd keynote demonstrations. Microsoft also made it as a way to be eligible to win one of 5 Portable Media players. The RFID was only active when we were in certain areas of the Convention Center. The RFID is pictured here behind a sticky label.. I hadn’t ever seen one before but I have heard a lot about them.
