I am completely lost. I'm doing a project using rfid. I want to use a transponder powerd by 12v that will power a 12v light from at least 3 feet away from the reader and cut off when I gain distance. I found this kit on the net but it doesnt have the distance I need:
The kit consists of an RFID reader coupled with a 125KHz antenna. The kit comes with two RFID keyfob tags. Extra tags are available in two formats, Keyfob or Disc. The Keyfob as it's name suggests can be attached to a keyring, whilst the Disc can be put into a wallet or purse.
The read range is 50mm - 75mm.
The tags have unique serial numbers allowing only tags which have been programmed in to the RFID reader by the master programming fob to activate the reader output.
The reader has a 12v output which is active for as long as the keyfob is held in front of the RFID reader's antenna.
This output can be used to drive a relay which in turn unlocks a door latch.
The reader unit runs from 9V to 15V DC.
You can program up to 25 RFID keyfobs per reader.
I need to atleast have a distance of a foot or two. Thanks
