Reverse PIN on ATM's

Recently there has been surge on cash snatching on ATMs at gun point. Various videos have been circulating around in Karachi---most of the time the event happens when the ATM is placed inside an enclosure.

Concerned people have also started forwarding emails which say that you can save yourself in such a situation by entering your ATM PIN in reverse order; further claiming that doing so will alert the police before giving you the cash. If you discuss this with any IT person working in a local bank, he/she will definitely tell you that it's not true. There is no such thing as reverse PIN checking on bank's ATM controllers. Nor there is any built-in mechanism to alert the police.

A letter to the editor in Dawn surprised me that there is a patent on this idea! This is known as ATM Safety PIN!
