The Proxmark3 Dev Kit 2 (RDV2) from Elechouse is more portable and brings various improvements to the open source design. Antennas are improved and the connection is through mmcx cables which are a lot easier to find and work with. Antennas can be mounted on the device in various configurations and easily held. An optional 3.7v battery can be placed inside the shell and powering the device is still possible with external USB batteries.
Whether you’re in the field, in the lab, or in the classroom, the Proxmark3 is the RFID tool of the trade when it comes to sniffing, reading, and cloning RF Tags. Proxmark3 can run independently from a PC powered by an optional 3.7 V battery, and offers depending on the targeted RFID Tag advanced functions like Offline Encryption, Online sniffing, default key cracking, data dumping, or the ability to run simulations. It is currently the “gold standard” when it comes to RFID research.
Developed back in 2007 by Jonathan Westhues and published under General Public License, the Proxmark3 has made its way from a DIY project to an almost ready-to-use device capable of analyzing the RFID communication at low frequencies (125 KHz) and high frequencies (13.56MHz).
RFID was first introduced for identification purposes only, but was quickly adopted for other applications in commerce and transportation. RFID technology is now in widespread use for a variety of applications across many industries. In 2006, Westhues was hired by California State Senator Joe Simitian to illustrate the ease with which state lawmakers’ RFID-based ID cards could be read and cloned. He successfully read and cloned the ID card of California State Assembly member Fran Pavley, who remarked, “All that was done within a moment’s notice of time without me even being aware of it.”
Each unit is pre-flashed with pm3-bin-2.5.0
