And if you have ever worked with an ATM, you know that it is impossible to 'crack' one the way John Connor did.
When a card is inserted into an ATM, it reads the mag stripe on the card. It does not do multiple reads (as in hundreds) and the card reader can NOT accept the card PIN. The PIN comes from the keypad. There's no way an ATM could ever accept a PIN from the card reader.
After three tries with a PIN the card is disabled.
But it looked good on the screen!
I did ATM projects for NationsBank in the 1990's. We used to joke about cracking our ATMs a la John Connor.
