Welcome to the Project

Note: As of January 2014, this site is discontinued.

The development continues on the new ChameleonMini
github site.

Chameleon is a versatile emulator for ISO 14443 contactless smartcards. It is meant to be a programmable platform to assess security aspects in RFID environments and can be used in different attack scenarios like replay or relay attacks and even for emulating an existing smartcard, thus behaving as a perfect clone of a given card.

The Chameleon Project has been started by the Chair for Embedded Security at the Ruhr-University in Bochum, Germany and has been licensed as open source to let everyone benefit from the work that has been done so far.
We are always looking forward to any means of contributing or contacting us.


Lately, we have been working on a second version of Chameleon, namely Chameleon-Mini, which builds upon the success and experience we have had with the first version of Chameleon.
It is reduced in size and has more functionality compared to the first version of the Chameleon.

The Chameleon-Mini has been moved out to github. See here
