RFID sniffer

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.

RFIDuino is an Arduino shield for reading and writing 13.56 MHz RFID
tags. It consists of a 65x65mm circuit board, which plugs upside-down onto a
standard Arduino (NG, Diecimila, Duemilanove, or BlueTooth).
The board has a build-in antenna and contains all the circuitry to read and write 13.56 MHz ISO-14443A (Mifare) RFID tags. It is connected to the Arduino by I2C, using the Wire library.


I build a prototype during Picnic '08, documented here.
The production version will be available in my web shop from early April.
