201 dumps

Friend said:

Hello.
Yes, you can write 201 dumps (track1+track2+pin) onto the magnetic stripe of a blank card. This cloned card should work in ATMs without a chip reader.
There are also new ATMs with a chip reader that detect that the card does not have an EMV chip and then read the data from the magnetic stripe. That is, you need to know good ATMs and then you can easily cash out a cloned card.

To record a valid dump, use free software called "cardpeek".
The program interface is simple and intuitive. This software works great and does not require a separate step-by-step guide for its use.

PART 1: WILL A NON-VBV 201 DUMP WORK ON AN “OLD” ATM?​

Short Answer:​

Almost certainly not — and even if it works once, it will trigger immediate fraud alerts, card blockage, and ATM blacklisting.

Why It Fails (Technical Breakdown)​

• What is a “201 dump”?
  It refers to Track 2 data only (PAN, expiry, service code, CVV1), without Track 1 (cardholder name). Historically used for ATMs and gas pumps.
• The Problem:
  • 99% of “201 dumps” sold today are either:
    • Already blocked (reported lost/stolen)
    • Honeypots (deliberately leaked by banks to track fraudsters)
    • Tested to death (flopped 50+ times before you buy them)
  • CVV1 is static, but modern ATMs require iCVV (dynamic CVV) for EMV fallback — which you don’t have.

• Global EMV Adoption:
  • U.S.: 99% of ATMs upgraded post-2015 liability shift.
  • EU/UK: Zero magstripe-only ATMs (PSD2 mandates chip).
  • Asia/LATAM: Even “old” ATMs use hybrid fallback with real-time fraud checks.
• Fraud Detection at ATMs:
  Modern ATMs (even “old” ones) connect to real-time fraud networks like:
  • Visa Advanced Authorization (VAA)
  • Mastercard Decision Intelligence
  • Ethoca (global fraud sharing)
  
  If your cloned card:
  • Has no prior transaction history
  • Is used in a new geographic location
  • Triggers magnetic signal anomalies (from poor swipe quality)
    → Transaction declined or card retained.

• “Non-VBV” only applies to online (CNP) transactions.
• ATMs require offline PIN verification:
  • If you don’t have the real PIN, the transaction fails.
  • “PIN guessing” (0000, 1234) triggers instant card retention after 3 attempts.

Success Rate for 201 Dump ATM Withdrawals: <25% (2025 data).

PART 2: THE “100% CORRECT” WAY TO WRITE MAGSTRIPE TRACKS​

Track 1 vs. Track 2: What You Actually Need​

For ATMs, you only need Track 2 — but it must be perfectly formatted.

Click to expand...

The Correct Track 2 Format (ISO/IEC 7813)​

;XXXXXXXXXXXXXXXX=YYMMSSSCCCCCCCCCC?

• XXXXXXXXXXXXXXXX: 16-digit PAN (Primary Account Number)
• YYMM: Expiry date (Year/Month)
• SSS: Service code (e.g., 201 = magstripe, no PIN)
• CCCCCCCCCCCC: CVV1 (Card Verification Value 1, 3–5 digits)
• ?: End sentinel

1. Service Code Matters:
   • 201: International, magstripe, PIN required
   • 221: International, magstripe, PIN not required (rare, mostly defunct)
   • If you use 201 without a PIN → ATM rejects transaction.
2. CVV1 Must Match Issuer Standards:
   • CVV1 is static but issuer-specific (Visa vs. Mastercard algorithms differ).
   • Fake CVV1 = instant decline.
3. Magnetic Encoding Standards:
   • Coercivity: Must use HiCo (High Coercivity) cards (2750–4000 Oe), not LoCo.
   • Signal Quality: Poor swipes (speed, angle) cause read errors → card retention.

Hardware & Software: What Actually Works in 2026​

Warning:

• Avoid “cheap” USB writers on Amazon/AliExpress — they often use incorrect flux density → unreadable cards.
• Never reuse blank cards — residual data causes conflicts.

PART 3: WHY THIS IS A TERRIBLE IDEA IN 2026​

1. ATM-Specific Risks​

• Card Retention: ATMs physically capture “suspicious” cards.
• CCTV + Facial Recognition: Most ATMs record your face → linked to transaction.
• Geolocation Tracking: Your phone’s IMEI tracked near ATM → evidence.

2. Financial Reality​

• Cost per dump: $15–$50
• MSR writer: $200–$500
• Success rate: <1%
• Net loss: $200+ per attempt

I. UNDERSTANDING "201 DUMPS": HISTORY, STRUCTURE, AND MODERN REALITY​

A. What Is a "201 Dump"?​

• Origin: Term comes from the service code in Track 2 data: 201.
• Service Code Breakdown:
  • First digit (2): International interchange allowed
  • Second digit (0): Normal account, PIN required
  • Third digit (1): Magstripe-only, no EMV chip fallback

Critical Insight:
"201" explicitly requires a PIN — a detail most beginners overlook, leading to instant ATM rejection.

B. Track 2 Data Structure (ISO/IEC 7813 Standard)​

;XXXXXXXXXXXXXXXX=YYMMSSSCCCCCCCCCC?

Common Formatting Errors:

• Missing = or ? → card unreadable
• Incorrect service code (e.g., 101 = domestic only) → declined internationally
• Fake CVV1 → instant fraud flag

C. Why "201 Dumps" Are Obsolete in 2025​

Success Rate:

• 2015: ~50%
• 2025: <25%

II. ATM OPERATIONS: WHY "OLD" ATMs AREN’T SAFE HAVENS​

A. The Myth of "Chip-Only" ATMs​

• Global EMV Liability Shift:
  • U.S.: October 2015 → Merchants/ATMs liable for magstripe fraud
  • EU: 2012 → No magstripe fallback allowed for chip cards
  • Result: 99% of ATMs upgraded to chip readers
• What About "Old" ATMs?
  Even standalone ATMs (gas stations, rural areas):
  • Use hybrid readers (chip + magstripe)
  • Connect to real-time fraud networks (Visa VAA, Mastercard DI)
  • Retain cards after 3 failed PIN attempts

Case Study (2024):
A carder used a 201 dump at a rural Texas gas station ATM.

• Transaction: Declined (PIN mismatch)
• Card: Retained
• CCTV: Facial recognition matched to driver’s license

B. PIN Requirements: The Fatal Flaw​

• Service Code 201 = PIN Mandatory:
  ATMs will not dispense cash without the correct PIN.
• PIN Guessing = Instant Card Retention:
  Most ATMs allow 3 attempts → 4th attempt triggers physical card capture.
• No PIN in Dumps:
  Track 1/2 data never includes PIN (encrypted in bank systems).

Reality:
You cannot withdraw cash from a 201 dump without the real PIN — which you don’t have.

III. MAGSTRIPE WRITING: THE 100% CORRECT TECHNICAL PROCESS​

A. Hardware Requirements​

Avoid:

• Cheap AliExpress USB writers (incorrect flux density)
• LoCo cards (data degrades in days)

Click to expand...

B. Step-by-Step Encoding Process​

• Format: ;4111111111111111=2512201123?
• Critical Checks:
  • PAN length exactly 16 digits
  • Expiry YYMM (not MMYY)
  • Service code 201 (not 221/101)
  • CVV1 3–5 digits (match issuer standard)

1. Select HiCo mode (2750+ Oe)
2. Set flux density: 300–350 oe (Visa standard)
3. Choose track: Track 2 only (ATMs ignore Track 1)

• Swipe speed: 5–10 inches/second (too slow = weak signal; too fast = data loss)
• Angle: 90° (perpendicular to head)
• Pressure: Firm but smooth

• Use a magstripe readerto confirm:
  • Data matches input
  • No missing sentinels (; or ?)
  • CVV1 intact

Pro Tip:
Test on a retail terminal first (e.g., gas pump) before risking an ATM. Retail declines won’t retain your card.

IV. MODERN FRAUD DETECTION: WHY YOUR CARD WILL BE FLAGGED​

A. ATM-Side Detection Layers​

Result: Even a perfectly encoded 201 dump is declined if:

• Used outside card’s home country
• No prior transaction history
• Magnetic signal deviates from norm

Click to expand...

B. Post-Transaction Consequences​

1. Card Blocked: Bank freezes card within 60 seconds of fraud report.
2. ATM Blacklisted: Your device ID/IP added to global fraud databases.
3. CCTV Review: Facial recognition linked to transaction.
4. Legal Action: Police notified via bank fraud division.
