Introduction: What’s Proxmark 3 RDV4?
The Proxmark 3 RDV4 is a dedicated, highly-capable multi-tool for RFID (Radio Frequency Identification) analysis, providing:
- reading, writing, analysis, snooping, replaying, emulation, modulation, demodulation, decoding, encoding, decryption, encryption (125kHz – 13.56MHz).
This latest revision of the Proxmark 3 Platform, originally developed by Jonathan Westhues in 2007, is specifically designed for the pentesting community. The Proxmark 3 RDV4 is a fully revised, modernized version of the already powerful RDV2.
Proxmark 3 RDV4 [design, hardware specs, features]
The Proxmark3, often referred to as the Swiss Army Knife of RFID research, is a powerful general purpose RFID tool, the size of a deck of cards, designed to snoop, listen and emulate everything from Low Frequency (125kHz) to High Frequency (13.56MHz) tags.
It can act as a reader/writer. The Proxmark 3 can analyze the signal received over the air and it can also pretend to be a tag itself (RFID sniffing [both ways], reading, writing, emulating and cloning). The Proxmark3 RDV4 can operate in three different modes: sniffing mode, card emulation mode, and reader mode. You can use the Proxmark3 for different modulation schemes and protocols as long as there are in the supported frequency range.

- Expandable: BLE/Wifi module expansion capability for automated data egress
Hacking with Proxmark 3 RDV4
It’s a neat tool to read, write, clone, bruteforce, emulate a lot of known RFID protocols, and one and only capable of both transmitting and receiving. The Proxmark3 has proven itself to be an invaluable tool within the pentesting/hacking community.
- Proxmark 3 RDV4 is small-sized device, fits easily into a hand and pocket.
- Wherever you are (in the room, lab, or in the field), the Proxmark3 RDV4 is the perfect RFID tool when it comes to sniffing, reading, and cloning RF Tags.
- It can run independently from a PC powered by an optional battery, which allows you to preform advanced actions, such as: online sniffing, key cracking, offline encryption, data dumping, etc.
- Compared with other compatible RF cloning devices available on the market, Proxmark3 RDV4 is under constant development. It’s well documented, there are forums and communities to help you with setup and other problems you may encounter.
- You can hack RFID, which allows you to preform smart lockpicking (Cracking Mifare Classic cards, decoding data and cracking hotel rooms cards/master hotel card, Mobile NFC access control, etc.).
- It allows you to hack: hotel rooms, car keys, public transport systems (trains, buses, trams), ski pass, football, museum tickets, e-wallets, loyalty cards, Contactless payments, passports, and so much more.
- Proxmark3 RDV4 is a great little device for physical pentesting, which allows you to capture, replay and clone almost all of RFID tags.
Proxmark3 RDV4 is available for online purchase, you can buy ready-to-go kit for about $400-500. Some of the available starter kits include: Proxmark3 RDV4 unit, plastic enclosure, dual HF/LF antenna, two test cards (5577, Mifare 1k S50 compatible), usb cable, and small screw driver.
Naked Proxmark3, Enclosed Proxmark3, LF/HF Antenna can be purchased separately. If you find it too expensive, you can build one yourself, but that will require some reasonable knowledge/skills.
The Proxmark3 RDV4 is currently the “gold standard” when it comes to RFID. Currently, it’s the only device readily available for executing both cloning and skimming attack, as a portable/modular platform that can both read and emulate contactless cards. The entire Proxmark3 platform is open source, including hardware and software, so it can also be used for educational purposes.
