PIN Number Reversal

I got this information from Anuradha (friend of mind) wanted to share with you all as its knid of important, but don't no how true it is.

THIS WAS SENT TO ME BY A HEAD OF A LEADING BANK IN SL.

PIN NUMBER  REVERSAL (GOOD TO KNOW)

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.

This  information was recently broadcasted on TV and it states that it is seldom used because people don't know it exists.
