A Technical RFID Primer

Posted by Hemos on from the learn-more-about-it dept.

gManZboy writes "Roy Want, principal engineer at Intel Research, has a pretty meaty technical overview of RFID up at Queue. If you ever wondered how these little things actually work it's worth a read. For instance, I was intrigued to find out how the tags (which are generally battery-free) can absorb enough energy from RFID readers to then power up and transmit their own signal back to the reader."

    I wonder what the long term effects for RFID under the skin would be, anyone seen anything on this?
    With that kind of focus of energy consistently in one area...well hmmm.
