ProxLF antenna for the Proxmark3 RDV4

The ProxLF antenna is finally here! Designed exclusively for use with the proxmark3 rdv4, this 125kHz “LF” antenna is so powerful, it can talk to our 125kHz implants like the xEM and NExT from 2cm away! It’s even so powerful it can even talk to the xEM while it is still inside the injection assembly needle! GET IT!

More Details

Our 125kHz implants like the xEM and NExT contain the T5577 chip, which is capable of emulating many different types of 125kHz ID chips including EM41xx, EM42xx, HID ProxCard, Indala, AWID, and others. However the T5577 chip does not support tear protection, so if you attempt to change the configuration of the T5577 without a good coupling (i.e. a good matching antenna on the reader), it’s possible to “brick” the chip so it will not communicate properly. Take heart! The ProxLF is specially designed with a cylindrical inductor that shapes the lines of magnetic flux to perfectly couple with the small cylindrical antennas inside our x-series chip implants.

Hey! It’s a Proxmark3 RDV4!
Developed back in 2007 by Jonathan Westhues and published under General Public License, the Proxmark3 has made its way from a DIY project to a ready-to-use device capable of analyzing the RFID communication at low frequencies (125kHz) and high frequencies (13.56MHz).

The Proxmark3 Dev Kit 4 (RDV4) from RRG/ProxGrind is a compact/portable version of the Proxmark3 that brings a number of innovative improvements to the open source design. Its antennas are highly customizable and there is a new multifunction multiplexing interface to support additional components such as external battery, external active high powered antenna, Bluetooth interfaces, and more. The new model replaces RDV3 (aka PM3 Easy), RDV2, and the original PM3 design.

2019-07 / 4.01 update notes: Multiple device improvements over the 4.0 version:

  • Gold-plated FPC Connector
  • Antenna “Q-Switch” allowing for adapting antennas to specific operations
  • Antenna Frequency Switch allowing for optimised 125KHz and 134KHz performance
  • Reduced power supply noise

Includes: Proxmark3 RDV4 unit, plastic enclosure, dual HF/LF antenna, two test cards (5577, Mifare 1k S50 compatible), SIM/SAM (Subscriber Identity Module / Secure Access Module) extender, usb cable, and small screw driver. 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 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.
 

Features

  • Read just about any RFID tag
  • Pretend to be a reader or a tag
  • Sniff communications between a reader and tag
  • Operate in standalone mode without a PC (USB battery required)

Advantages & Benefits

Compared with other on the market available Proxmark-like and RF cloning devices, the Proxmark3 is under constant development and the RDV4 offers the following improvements:

  • Improved LF and HF antennas design for portability
  • Improved shell
  • Multi-function expansion port
  • 4 mode LEDs, 4 power LEDs, User button
