RFID sniffer

About this project

RFID is everywhere. Use the easy to build RFID sniffer to find out if objects are tagged.
The RFID sniffer is a simple analog electronic circuit which can detect the presence of 13.56 MHz RFID tags. These tags are commonly used in all kinds of plastic cards like access badges, bank cards, library cards, loyalty cards and so on. Also many other objects may carry RFID tags without you knowing it. Books, toys, and even clothing might be tagged. Carrying tagged objects with you can reveal your identity or whereabouts to anyone equipped with the appropiate tools to read RFID tags.
The RFID sniffer helps you identify which objects are tagged, and which are not.

RFID sniffer delivery

RFID sniffer Posted on 2009-04-06 11:12

Electronic parts of RFID sniffer kits are back in stock, but I’m still waiting for the lanyards and sleeves. They are currently in production, and will be shipped to me this week. I will send out all RFID sniffer kits immediately upon arrival of the lanyards.
If anybody who already ordered can not wait any longer, and wants to start soldering right away, please let me know and I will ship the kit without lanyard and sleeve and ship those afterwards at no extra cost.
Apologies for the unexpected delay.

RFID sniffer in MAKE magazine

One step closer to eternal fame.. I’m in MAKE magazine!

Ironically, I was in New York instead of Amsterdam at the time of publishing, so I could not handle the wave of new orders resulting from this blog post. Shipping will resume as soon as all parts are back in stock.
