PIN NUMBER REVERSAL (VERY IMPORTANT TO KNOW)

I got this in one of the forward mails and not sure if this is true. I think it is applicable only in India, though not sure.

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. Please pass this along to everyone possible.

I stand corrected
This is a hoax.
