ATM safety

If someone force you to withdraw money from ATM , THEN......
If you are ever forced by a thief or someone to take money out of an ATMmachine, enter your pin number reversed.
So if your number is 1254 mark 4521.
The ATM machine will give you your money, but will automatically recognizethis as a plea for help and will alert the police unknown to the thief.
This option is in all ATM machines, but not many people know this.
Please pass this information on to others. No harm in keeping this in mind!!
