This is one of the top secrets of ATM machines. If at any point of time you are forced at a wespon point buy theives to take out money from ATM. Just type your ATM pin in reverse order, for example your ATM code if 1234, type it as 4321. The money will be dispensed but simultaneously an alarm will be triggered in a near by police station to that ATM. So, the cops will be there in a minute or 2 & theives will not even be aware they will be caught.
Isn’t it a greatest secret. But caution: do not try just for the sake of trying it. If you are trying it without any reason, instead of theives you will be inside the jail.
Another fact is that, an ATM is always installed within the range of police station in any area.
