If you should ever be forced by a robber to withdraw money from an ATM machine, you can notify the police by entering your Pin # in reverse.

For example if your pin number is 1234 then you would put in 4321. The ATM recognizes that your pin number is backwards from the ATM card you placed in the machine.

The machine will still give you the money you requested, but unknown to the robber, the police will be immediately dispatched to help you.

Zingher is the inventor and patent holder for the ATM SafetyPIN software. Say you get held up at night withdrawing money from a teller machine. Type in your PIN backwards and the ATM will call the cops, just like dialing 911 or pushing a panic button. The robber won't know a thing, since the transaction will proceed and money will be dispensed.
