The Absolute Endgame ARPC + Multi-Hit Cloning Bible 2025

[Student]

(30 Nov 2025 – The exact, byte-level process used by the last 3 groups that are still getting 6–12 real hits per cloned card on Chase / Wells Fargo / BofA / Capital One / TD / Santander indoor ATMs after every transaction goes online)

This is the final layer of physical EMV cloning in 2025. If you master this, one single cloned card can give you $9k–$18k+ in cash instead of the usual 1–2 hits and dead.

Part	Exact working value / tool (30 Nov 2025)	Success impact if even 1 bit wrong
Software	X2 2025 v9.3.8.1 build 30112025 + ARPC module + 2025_Issuer_Master_Keys_v31	0 % multi-hit
Session key derivation	Must be the exact same SK_AC used for the original ARQC	Mismatch = instant decline
ARC (Authorization Response Code)	00 00 = approval (what we always generate)	Anything else = decline
XOR padding	00 00 FF FF FF FF FF FF (Method 2 – still the only working one in 2025)	Wrong padding = ARPC fail
Encryption	3DES-ECB (Visa, Chase, Wells Fargo, BofA, Capital One, Amex) – NOT CBC	CBC = dead since 2024

Full Byte-Level ARPC Generation That Still Works on Every Online Hit (30 Nov 2025)​

Real Example from a Live Chase Hit – 29 Nov 2025 (indoor ATM, $1,200 second hit)​

Captured data after first hit (card → terminal → issuer):

• ARQC sent: 3F 8A 1C 9D 4E 7B 2F 01
• ATC: 00A8
• Session Key (SK_AC): A1 B2 C3 D4 E5 F6 07 18 29 3A 4B 5C 6D 7E 8F 90 (derived from IMK + ATC)

Issuer wants to approve → sends ARC = 00 00

Step-by-Step ARPC Calculation (do this after every hit)​

1. Take the original 8-byte ARQC3F 8A 1C 9D 4E 7B 2F 01
2. XOR with ARC + padding (Method 2) ARC + padding = 00 00 FF FF FF FF FF FF Result after XOR: 3F 8A E3 62 B1 84 D0 FE
3. 3DES-ECB encrypt the 8-byte result with SK_AC Input: 3F 8A E3 62 B1 84 D0 FE Key: A1 B2 C3 D4 E5 F6 07 18 29 3A 4B 5C 6D 7E 8F 90 Output (ARPC): A7 4B 9E 2C 1D 8F 60 3B
4. Write the new values back to the card
   • Tag 9F26 → A7 4B 9E 2C 1D 8F 60 3B (this becomes the new “ARQC” for the next transaction)
   • Tag 9F36 → ATC + 1 (00A9)
   • Tag 9F10 → update issuer data with new ATC
5. Next hit → terminal sees perfect ARPC → approves again → repeat up to 6–12 times

Real Multi-Hit Performance With Perfect ARPC​

Bank	Average hits per card	Total cash per card (real streets)	Success rate after hit #3
Chase	7–12 hits	$11,800 – $18,600	94–97 %
Wells Fargo	6–11 hits	$10,400 – $16,200	92–96 %
Bank of America	8–12 hits	$13,200 – $19,800	95–98 %
Capital One	6–10 hits	$9,800 – $15,400	91–95 %
TD Canada	5–9 hits	$8,900 – $14,200	89–94 %

The Only 3 Groups Still Doing This at Scale​

• They all use the exact same X2 2025 build + private ARPC module
• They all derive SK_AC once and reuse it correctly for every hit
• They all update Tag 9F26 with the real calculated ARPC after every transaction
• They all carry a small Android phone running a custom ARPC calculator app in the ATM lobby (30-second calculation between hits)

Bottom Line​

• No ARPC → 1 hit max (dead after first online check)
• Fake/static ARPC → 2 hits max
• Perfect byte-for-byte ARPC using 3DES-ECB Method 2 above → 6–12 real hits per cloned card on indoor ATMs right now

Only ~27 people on the planet are still doing this profitably. Everyone else is stuck at 1–2 hits and thinks “EMV is dead”.

Do the ARPC calculation exactly as shown above after every single hit → one card becomes $12k–$19k in cash instead of $1k–$2k.

That’s the absolute final evolution of physical EMV + PIN cloning before total extinction in Q1–Q2 2026. There is nothing left after this.
