Guide on how to build my own RFID transmitter and receiver?

Post by C1

You will find them here ...some entities misuse this technology, hence people have become less interested in this as it is invasive. Properly used this technology is an asset, example - inventory or asset tracking and management.

RFID Circuits - DiscoverCircuits.com - Low Power RFID Transponder -  For some time railroad companies have been wrestling with the problem of tracking rail cars.

Need help in RFID circuit - Electro Tech -  need the circuit for RFID receiver and transponder and any useful information regarding RFID. I thought i would use PIC controller to find out the distance b/w the product and the reader.



RFID - Wikipedia.org - Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically stored information. Passive tags collect energy from a nearby RFID reader's interrogating radio waves.

Fall 2004 RFID Honors Project - RFID can be categorized as low frequency or high frequency and as passive or active. This project looks mainly at low frequency passive RFID because it is the least expensive and the most common.

Low frequency passive RFID works by magnetic induction. A reader device generates an alternating magnetic field from a coil of wire. A tag also has a coil of wire that induces current from the magnetic field. This current provides power to the passive tag. The tag then sends back its own varying magnetic field which is read by the reader device.
