Interesting behavior of ATM I discovered today. I wanted to put cash on my bank account using ATM.
* I inserted card
* I entered PIN code
* I inserted the cash
* ATM counted the cash
* I chose "Transfer money to account"
* ATM said "Wrong PIN"
* I entered the right PIN
* ATM transfers money to my account
Why the PIN verification procedures at this stage? What if I enter the wrong PIN 3 times? Does it give me my cash back?
