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."

    Tinfoil ON!. Everyone knows they get there energy from stealing your soul a little at a time, sucking the very life essence from your body. Then when they have all your energy they march you into a retirement home which is just a block away from the new universal nutrient - soylent green! Tinfoil OFF!
