Proxmark3 Easy vs RDV4: which one to buy?
Proxmark3 Easy vs RDV4: hardware differences, antennas, flash size, build quality and euro prices, plus which model suits which kind of user.
For most learners, the Proxmark3 Easy is enough: it shares the RDV4's architecture (ARM microcontroller, FPGA, low and high frequency) and runs the same community firmware for roughly a quarter of the price. The RDV4 earns its price in regular professional use: a compact case, tuned and swappable antennas, extra memory, a smart card reader and add-ons. The one real trap when buying an Easy is its flash size.
The Proxmark3 is a research tool. It is for understanding how contactless cards work and testing systems you own or are authorised to assess. This comparison is only about hardware and buying.
RFID vs NFC in two minutes (125 kHz and 13.56 MHz)
Contactless cards fall into two broad families by frequency.
| Low frequency (LF) | High frequency (HF) | |
|---|---|---|
| Frequency | 125 / 134 kHz | 13.56 MHz |
| Examples | Older building fobs, pet microchips | MIFARE, NTAG, DESFire cards, passports, transport cards |
| Typical range | A few centimetres | A few centimetres |
| Readable by a phone | No | Yes, for the NFC part |
NFC is the slice of high frequency standardised for phones. So your phone reads some HF cards and no LF cards at all. That is the first reason to buy a Proxmark: it covers both bands, with an antenna for each, and lets you observe in detail what happens between a card and a reader.
To pick cards for your experiments, our guide to blank NFC cards (MIFARE, NTAG, DESFire) compares the chips one by one.
Proxmark3 Easy: what you get for the money
The Easy is a simplified, mass-produced version of the Proxmark3. It keeps the core architecture:
- An ARM microcontroller from the AT91SAM7S family, which runs the firmware and talks to your computer over USB.
- An FPGA, a programmable logic chip that processes the radio signals in real time. Despite what you may read on forums, the Easy does have one.
- A low-frequency and a high-frequency antenna, on or attached to the board.
- Buttons and LEDs for standalone modes.
What the Easy lacks, or doesn't always have:
- A case. The Easy often ships as a bare board or in a basic enclosure, so it's more fragile in a bag.
- Factory-tuned antennas. Performance varies from unit to unit, especially on low frequency.
- The smart card reader (SIM-sized) and the RDV4's expansion connector.
- Guaranteed internal flash. Depending on the manufacturer, the chip has 512 KB or only 256 KB. More on that below: it is the number one buying criterion.
On price, expect about €80 as of October 2026 for a 512 KB Easy with the Iceman firmware preinstalled from a specialist European reseller. Asian marketplaces list lower prices, with more uncertainty about the chip, antennas and firmware you'll actually receive.
Worth knowing: the official proxmark.com site now describes the original Proxmark 3 Easy (with a 256 KB chip) as obsolete and points to newer models. That doesn't make today's 512 KB Easy boards useless, but it's one more reason to check exactly what you're buying.
Proxmark3 RDV4: what the extra money buys
The RDV4 (now in its RDV4.01 revision) is the reference platform, the one the Iceman firmware builds for by default. According to its maker and distributors, it adds:
| Feature | What it changes |
|---|---|
| AT91SAM7S512 microcontroller (512 KB) | Room for the full firmware, no trade-offs |
| 256 KB (2 Mbit) external SPI flash | Store dictionaries, scripts and data on the device |
| Smart card reader (SIM-sized) | Work with contact smart cards and SAM modules |
| Pre-tuned internal antennas | Consistent performance from one unit to the next |
| Swappable antennas (mid and long range, optional) | Match the tool to the card or reader under study |
| Expansion connector | Bluetooth and battery module ("Blue Shark") for cable-free work |
| 54 × 87 × 10 mm ABS case | Credit-card footprint, built for field use |
The price reflects it: as of October 2026, expect about €330 for the standard edition and about €530 for the complete edition (extra antennas and wireless module) from an official European distributor.
What you're not paying for is "superpowers". For most learning work, a well-chosen 512 KB Easy and an RDV4 run the same firmware and the same commands. The difference is consistency, portability, comfort and expansion, which matters most when the tool is used daily on engagements.
Side-by-side comparison and verdict by profile

| Smart card reader | No | Yes |
| Bluetooth / battery add-on | No | Yes (optional) |
| Case | Bare board or basic enclosure | Compact ABS case |
| Iceman firmware | Yes (generic platform) | Yes (default platform) |
| Indicative price (Oct 2026) | About €80 | About €330 to €530 |
You're learning, on your own or at school. Get a 512 KB Easy. Same concepts, same firmware, and you'll find out later whether you need more.
You're a teacher or trainer equipping a room. The Easy gets you one tool per pair of students for the price of a single RDV4. Keep a spare or two, since quality varies.
You're a pentester and the tool goes on engagements. The RDV4 is worth it: consistent antennas, a case that survives a bag, cable-free work, a smart card reader. Time saved on site pays back the difference.
You're still unsure. Start with the Easy. It stays useful as a second tool or a training tool even if you move to an RDV4 later.
Distributors also list newer models (Proxmark 3 EVO, Proxmark 5). We haven't evaluated them yet, so they're not part of this comparison.
Choosing an Easy: flash size, Iceman firmware, antennas
Flash size: 512 KB, not 256 KB
Some Easy clones only have a 256 KB chip. The community firmware outgrew that size long ago: the project's documentation recommends at least 512 KB if you don't have an RDV4. A 256 KB Easy still works, but it needs a dedicated build configuration that drops features to make the image fit. For a first purchase, that's an avoidable hassle.
Before buying, ask the seller for the exact microcontroller part (AT91SAM7S512, not AT91SAM7S256). Once it arrives, the Proxmark client's hw version command shows the chip and available memory.
Firmware: Iceman
The reference firmware is the Iceman fork, maintained by the community in RfidResearchGroup's GitHub repository. It runs on Windows, macOS and Linux. The RDV4 is the default platform; the Easy builds with the generic platform (PM3GENERIC), and a 256 KB Easy adds a size setting:
# Excerpt from Makefile.platform for a 256 KB Easy (see the project docs)
PLATFORM=PM3GENERIC
PLATFORM_SIZE=256
Some resellers ship the Easy with Iceman preinstalled, others with old firmware. Updating it is covered in our Proxmark3 Easy Iceman tutorial.
Antennas
On an Easy, antenna tuning varies. The Proxmark client has a measurement command (hw tune) that reports the voltage on each antenna: it's the first check to run when the tool arrives. A poorly tuned antenna sharply reduces read distance.
What about the Flipper Zero?
The Flipper Zero isn't a direct competitor: it's a standalone multi-purpose device with a screen and battery that covers sub-GHz radio, infrared, NFC, low-frequency RFID and other interfaces. The Proxmark is a specialised tool, driven from a computer, dedicated to studying contactless cards. They are different categories of device. If you're choosing between general-purpose gadgets, read our guide to Flipper Zero alternatives, and for the legal picture around all these tools, see is the Flipper Zero legal in France?.

Frequently asked questions
Does the Proxmark3 Easy have an FPGA?
Yes. Like the RDV4, the Easy pairs an ARM microcontroller with an FPGA, a programmable logic chip that processes the radio signals. The idea that the Easy has no FPGA is a common misconception.
Does the Iceman firmware run on a Proxmark3 Easy?
Yes. The community Iceman firmware, maintained by RfidResearchGroup on GitHub, supports the Easy through its generic platform (PM3GENERIC). Easy units with a 256 KB chip need a dedicated build configuration that drops some features so the image fits.
How much do the Proxmark3 Easy and RDV4 cost?
As of October 2026, expect about €80 for a 512 KB Easy from a specialist European reseller, and about €330 for a standard RDV4.01 (about €530 for the complete edition with extra antennas and wireless module) from an official distributor.
Do I need a Proxmark to get started with NFC?
No. A phone and a few NTAG cards are enough to explore NFC. A Proxmark becomes useful when you want to study low frequency, observe the exchange between a card and a reader, or work on badges as part of research or authorised testing.
