If you want to create cloned cards and learn how to read and write chips (EMV) correctly, this is an important step in developing both carding and understanding how bank cards work. Below I will tell you in detail:

What is an EMV chip?​

EMV is a chip card technology standard named after the companies: Europay, Mastercard, Visa.

The chip contains:
  • Owner details
  • Cryptographic keys
  • Transaction logs
  • Unique codes for transaction confirmation

It is used instead of magnetic strip because it is much more secure.

What do you need to get started?​

1. Equipment​

DeviceDescriptionWhere to buy
Proxmark3 RDV4Read/write HF cards (Mifare, EMV)proxmark.com или AliExpress
ACR122U / ACR1252Smart Card Reader (for working with chips)Amazon, eBay
EMV USB Dongle (eg X2, MagTek)Full chip + magnetic stripe recordingCarder forums, darknet
Blank cards with chip + magnetic stripeFor cloningAlibaba, Taobao, eBay

Tip: Start with Proxmark3 RDV4 - it is the most affordable and powerful for studying chips.

Where to study? Education from A to Z​

1. YouTube channel​

  • Chris Paget - RFID and EMV Basics
  • Samy Kamkar – Security Research
  • DarkVapers - Practical Cloning Lessons
  • CarderPlanet Tutorials – there are video tutorials on the forums

2. Carders forums​

On carding forums you can find:
  • Guides for working with Proxmark3
  • How to decrypt PIN
  • How to read dumps from a chip
  • Examples of successful cloning

Basic Terms and Concepts​

KSNKey Serial Number (key number)
DDA / SDA / CDAChip Authenticity Verification Algorithms
TLVChip data format (Tag-Length-Value)

Step by step: how to learn to read a chip​

Step 1: Prepare the equipment​

  • Charge Proxmark3 RDV4, install drivers.
  • Download the official firmware from GitHub Proxmark3
  • Install software: PM3GUI or ProxSpace

Step 2: Connect the device to the PC​

  • Connect via microUSB.
  • Open the terminal and write:
Bash:
proxmark3.exe -d COM3
(where COM3 is the port of your device)

Step 3: Find the card​

In the terminal, enter:
Bash:
hf search

The device will find the card type (ISO14443A/B, Mifare, FeliCa, etc.)

Step 4: Read the chip​

If it is ISO14443A (EMV standard), enter:
Bash:
hf mifare readcard 0 A FFFFFFFFFFFF
or
Bash:
hf emv info

This will show the chip data: UID, ATQA, SAK, etc.

How to write a chip​

Option 1: Via Proxmark3​

  • Use commands:
Bash:
hf mifare writeblock <block> <keyType> <key> <data>

For example:
Bash:
hf mifare writeblock 4 B FFFFFFFFFFFF AABBCCDDEEFF00

Option 2: Via EMV reader (X2)​

  • Special software is used: MagStripe Studio, Smart Card Toolz, ChipDNA
  • You download the dumps from the chip and write it to the new card.

How to work with dumps​

You can get the dump:
  • From the original card (via Proxmark3)
  • From databases (forums, darknet)
  • Using POS readers

Step by step: how to work with dumps​

After you read the data from the chip, you get a so-called dump - this is a set of data in TLV (Tag-Length-Value) format. It contains:
  • PAN (card number)
  • Validity period
  • Owner's name
  • Cryptographic keys
  • Transaction information
  • Encrypted PIN (if any)

What does the dump look like:​

Code:
5F24 0A 231231000000
5F25 0A 231231000000
5F26 0A 231231000000
5F20 0C 4956414E 4F56204D 494B4841
5A 08 45323232 32323232 32
87 01 01
...

How to interpret it:​

Use the tools:
  • EMV Toolkit
  • Smart Card Toolz
  • DNA Chip
  • PyResMan / Proxmark3 CLI

For example, the command in the terminal:
Bash:
hf emv parse --file my_dump.bin

How to write a chip card​

There are several ways:

1. Via Proxmark3​

Suitable for Mifare and some EMV cards:
Bash:
hf mifare writeblock 4 B FFFFFFFFFFFF AABBCCDDEEFF00

Important: Not all chips support recording via Proxmark3. It depends on the type of chip and its protection.

2. Через EMV USB Dongle (X2, MagTek)​

This is professional equipment that allows you to:
  • Write full dumps (chip + magnetic stripe)
  • Work with encrypted PIN blocks
  • Change card parameters (name, expiration date, CVV)

Process:
  1. Open the software (for example, MagStripe Studio ).
  2. Load dump.
  3. Make changes (if necessary).
  4. Insert a blank card into the reader.
  5. Click "Write" or "Clone".

What is X2?​

X2 is a device that allows you to:
  • Read/write EMV chip cards
  • Working with PIN blocks
  • Supports ISO 7816 protocols
  • Compatible with most banking systems

It is often used together with software:
  • MagStripe Studio
  • SmartCard Studio
  • Track 1 & Track 2 Editor

The X2 is more expensive, but it is much more powerful than the Proxmark3, especially when working with US and European banks.

How to get a dump from a chip?​

1. From the original card​

  • Via Proxmark3 RDV4
  • Via EMV reader
  • Via POS terminals (via Bluetooth/USB)

2. From dump bases​

The following are sold on carder forums:
  • Dumps from the chip
  • PIN
  • CVV/CVC
  • Terms of validity
  • Owners details

You need to find:
  • Fresh dumps (valid, active)
  • With support for recording on the chip
  • With decrypted PIN or with brute-force capability

How to extract PIN?​

PIN can be:
  • Plain text
  • Encrypted block
  • Hashed

Extraction methods:​

  1. Brute-force through tables
    • Dictionaries and tables (rainbow tables) are used.
  2. Offline PIN decryption
    • Master key or KSN required.
  3. Online guessing
    • Dangerous, may block the card.

The best way: buy dumps with PIN or use ready-made tables for decryption.

Where to use cloned cards?​

PlacePossibility of use
Stores with POS terminals (without chip)✅
Gas stations, cafes, restaurants✅
ATMs (chip only)❌ without chip
Online stores❌ only physical cards
USA, CIS countries✅ higher chance of success
Europe, Japan❌ very high protection

Safety when working with chips​

  1. Don't use one card in different cities
  2. Don't make large purchases in one day.
  3. Change the appearance of the card (stickers, lamination)
  4. Use different IPs and devices when working with dumps online
  5. Don't use real data - create fake profiles

Yo, OP — killer thread, straight fire for the greenhorns dipping toes into EMV waters. Your Proxmark basics nailed the entry point, but let's crank this up to pro-level. Been grinding this scene since '22, flipped hundreds of dumps across Visa, MC, Amex, even some funky Discover bins. EMV's evolved a shit-ton by '25 — post-Quantum threats got issuers tightening CDA loops, and NFC fallbacks are down to ~60% on smart terminals thanks to Visa's VMP updates. But the game's still winnable with layered auth sims and hybrid writes. I'll dissect your outline, layer in advanced workflows, drop full code blocks, tool benchmarks, risk matrices, and real-world case studies from my logs. This ain't theory; it's battle-tested on EU/US ATMs and low-sec POS.

If you're cloning for "research" (wink), remember: feds love RICO on batches over 50. OpSec first — TOR + Tails, no logs, burn hardware post-run. Let's dive deep.

EMV 101: The Guts (Updated for '25 Standards)​

EMV ain't just a chip; it's a state machine enforcing DDA (Dynamic Data Auth), SDA (Static), or CDA (Combined) per EMVCo 4.3 specs (check emvco.com for the latest kernel diffs). Core flow:
  • Terminal Challenge: POS sends random (e.g., 8-byte UN).
  • Card Response: Chip crunches ARQC (Authorization Request Crypto) via session keys derived from ICC Master Key + diversified PAN.
  • Offline OK: If TC (Transaction Cert) pre-baked or ARQC validates, green light. No keys? Fallback to mag (but '25 terminals flag "chip decline" harder).

Key TLV Tags to Hunt (Expanded from Your List):
Tag (Hex)DescriptionLengthWhy It MattersDump Command Example
5APAN (Primary Account Number)Var (8-19B CD)Core ID; mask Luhn for tests00 B2 01 0C 00 (SFI 1, Rec 1)

8A/82CDOL1/CDOL2VarAuth/Compl Data Objects; bake ARQC hereGen via sim tool
DFEERecovery DataVarPIN try ctrls; rare gold for ATM skimsCustom applet read

Pitfall: Post-'24, Amex added token provisioning — dumps need ARF (Auth Req File) for contactless. Skip if no NFC blank.

Hardware Arsenal: Tiered Builds (Benchmarks '25)​

Your ACR122U shoutout is spot-on for starters, but scale smart. Here's a comparison — priced off darknet averages (AliExpress for proxies):
TierCore KitCost (USD)Read Speed (s/card)Write Success %Best ForDrawbacks
BudgetProxmark3 RDV4 + ACR122U8015-3070% (SDA only)Dumps/testsNo auto-crypto; USB flakies

BeastTangtop EMV Pro + Flipper Zero Dev + GlobalPlat Writer8001-395% (full CDA w/ precomp)Batch 100+Power-hungry; heat kills blanks
ExoticLab 3921 (bank-grade) + SDR (HackRF) for MITM2k+<198%Live auth captureOverkill; FCC bait

Must-Haves:
  • Blanks: JCOP 4.0+ (JCOP4J2E080) for '25 kernels — $3-6/ea in 100s. "Infused" whites (pre-loaded Visa applet) save 20% time.
  • Power: USB-PD hub; chips draw 5-50mA — brownouts corrupt writes.
  • NFC Add: PN532 module ($10) for contactless dumps—nfc-list via libnfc.

Firmware: Iceman's Proxmark fork (v4.2.2025) has EMV overhauls — hf emv exec --aid A0000000031010 --dump-full. Drivers: libccid 1.5+ for Win11; avoid macOS (APDU throttling).

Full Workflow: Read → Crack → Write → Launder (30-45min/Card)​

Expanding your steps with '25 tweaks. Assume Visa 201 dump to JCOP.
  1. Source Read/Dump (Enhanced Sniffing):
    • Setup: proxmark3 /dev/ttyACM0 or Python REPL.
    • Detect: hf search → ATR 3B 8F 80 01 80 4F 0C A0 00 00 03 10 10 00 00 00 (Visa AID).
    • PSE Select: hf 14a apdu -a 1 -p 00A404000E315041592E5359532E4444463031 (echo off for stealth).
    • AID Loop: Script to enum all:
      Bash:
      # Proxmark client script (save as emv_enum.cmd)
      script run hf_14a_emv_enum
      # Or Python (pyscard + emvlib)
      from smartcard.System import readers
      from smartcard.util import toBytes
      import emv  # pip not needed; assume lib
      
      r = readers()
      conn = r[0].createConnection(); conn.connect()
      SELECT_PSE = toBytes("00 A4 04 00 0E 31 50 41 59 2E 53 59 53 2E 44 44 46 30 31")
      data, sw1, sw2 = conn.transmit(SELECT_PSE)
      if sw1 == 0x90 and sw2 == 0x00:
          # Parse FCI for AIDs
          aids = emv.parse_fci(data)
          for aid in aids:
              SELECT_AID = [0x00, 0xA4, 0x04, 0x00] + list(aid) + [0x00]
              data, sw1, sw2 = conn.transmit(SELECT_AID)
              if sw1 == 0x90: print(f"AID {aid.hex()}: OK")
    • Full Dump: emv/dump_all in scsh3 (CardContact fork). Outputs JSON/TLV:
      JSON:
      {
        "5A": "4111111111111111",
        "5F24": "2512",
        "9F26": "masked_16bytes_here",
        "ARQC_sample": {"UN": "12345678", "resp": "ARQC_HEX"}
      }
    • Advanced: MITM live tx at POS — Proxmark as proxy: hf emv relay --challenge-gen. Captures real ARQC for replay. Success: 40% more auth hits.
    • Pitfall: "File not found" (6A85)? Card's in PIN-block; force offline with 00 20 00 80 08 00 00 00 00 00 00 00 00.
  2. Dump Processing (Crypto Deep Dive):
    • Parse: EMVLab.org (upload TLV) or local: tlvtool parse dump.tlv > readable.json.
    • Key Deriv: If IMK masked, brute via known UNs (from sniff) + DES3 algo:
      Python:
      from Crypto.Cipher import DES3
      from emv.crypto import derive_session_key  # Hypothetical lib; impl from GitHub emv-crypto
      
      imk = bytes.fromhex("YOUR_MASKED_IMK")  # Diversify if partial
      pan = "4111111111111111"
      un = bytes.fromhex("12345678")  # Terminal challenge
      session_key = derive_session_key(imk, pan, un)
      arqc = DES3.new(session_key, DES3.MODE_ECB).encrypt(b'\x00' * 8)  # Simplified; real is MAC'd
      print(arqc.hex())  # Bake into CDOL
    • IST Personalization: GlobalPlatform 2.3 — gpj -l -i jc_vmc_vdar_3_0.cap --default then --put-data 9F2A <ARQC_TLV>.
    • Fallback: Gen Track2: ;4111111111111111=2512201? via luhn_check lib.
    • '25 Update: Visa's token service — use ARF gen for virtual PANs; boosts contactless by 25%.
    • Tool Rec: EMV Writer v8.6 (crack via rutracker) — GUI for ARQC sim. Free alt: Python emvlib (GitHub).
  3. Blank Write & Emulation:
    • Prep: gp --unlock-isf 0x1234 (default PIN).
    • Load Applet: Download CAPs from carder.su — Visa: vmc_vdar_3_0.cap. gp -i --install vmc_vdar_3_0.cap --params params.xml (XML: AID, keys).
    • Inject Data: Batch APDUs:
      Bash:
      # GlobalPlatform CLI chain
      gp --put-data 5A 4111111111111111
      gp --put-data 5F24 2512
      gp --put-data 9F26 YOUR_IMK_HEX --secure
      gp --install-script ist.ac --params arqc_params
    • MSR Hybrid: X2 EMV: Import dump → "EMV + Mag" → Burn. Encodes stripe with chip PIN offset.
    • Test Suite:
      • Local: hf emv gen_ac --un 12345678 --expect ARQC → SW 9000?
      • Field: Low-stakes — gas pump (no CCTV), $5 auth. Monitor via app (e.g., ACR logs).
    • Advanced Emu: Chameleon for NFC replay—load dump as MIFARE, sim ARQC on-the-fly. Pairs with Flipper for batch tests.
    • Pitfall: 6985 (cond not satisfied)? Applet mismatch — use BIN-specific CAP (4=Visa, 5=MC).

  • US POS Skim (MC 101): MSR-only fallback. 15/20 success till Amex patch. Switched to CDA sim — upped to 18/20.
  • Fail Whale: Tried Discover on JCOP2 — 0% auth. Fix: Custom applet (GitHub forks). Cost: $200 blanks wasted.

Scaling & Next-Level Plays​

  • Batch 500+: Python orchestrator — pcsc + multiprocessing. Script: Loop readers, queue dumps to AWS (TOR proxy). $2k setup, 200/hr.
  • Beyond Clones: Token provisioning (Apple Pay dumps) — extract via iOS jailbreak + Frida hooks. Or Quantum-resistant? Nah, DES3 still king till '27.
  • OpSec 2.0: Blockchain launder (mixers dead; use privacy coins). Track issuer patches via dark RSS (e.g., visa.com alerts scraped).

Shoutout to your thread—sparked my last 30-clone run. Drop your dumps for review (anon paste), or Q on MC CDA? PM for CAP drops/scripts. Gear up, ghost quiet, but logs don't.
