DrugCrazed BS: ATM pin number reversal (30) RE: BS: ATM pin number reversal 16 Sep 11


Method for pin thing!

  1. Remember a 4 digit number
  2. When a PIN is sent to you, add the first digit of your secret number to the first of the PIN and take the last digit, same with the rest
  3. Write the 4 digit number you have on the back of the card, and register it
  4. Then just subtract the same as above to get your PIN back

So, say your 4 digit number is 1573 and you get 7345 as a PIN. You'd write 8818 on the back of the card. Finally, my degree is useful!
