This is the home page of a group of volunteer enthusiasts commited to further enhancing the capabilities of the already awesome Proxmark3, originally developed by Jonathan Westhues and release under the terms of GPL. You are encouraged to visit his site to read his original write up on the build of the proxmark3 as well as take a look at the historical progression from the basic prox to the markII to the final proxmark3. Please bear in mind that any statements on Jonathan's web site relating to the abilities of the board may be little dated now, and the capabilities of the proxmark3 have been (and continue to be) further enhanced, by great enthusiasts, such as Gerhard de Koning Gans who added ISO-14443a support and many others who continue to add features in their own time.

It can analyze the signal received over the air more closely, for example to perform an attack in which we derive information from the tag's instantaneous power consumption. It can pretend to be a tag itself. It is also capable of some less obviously useful operations that might come in handy for development work.
