Wireless RFID Smart Key Detector
Many cars now use a key with an imbedded RFID microchip.� The microchip is read when the key is inserted into the car's ignition.� The keys containing a microchip often look the same as most other keys. People duplicating car keys will often not know of the microchip.� This circuit will light a LED if it...

RFID tag antenna based temperature sensing in the ...
Abstract--The efficiency of cold supply chain operations can
be improved with pervasive temperature sensing. In this paper,
we investigate the design of a low-cost, single-use RFID based
temperature threshold sensor that is capable of relating the
violation of a temperature threshold to a shift in the optimal
operating frequency at which the tag antenna is well matched
to the tag IC. This shift...
