I read an article about this. Seems it’s not that way in the U.S., or wan’t when I read it. Started in Australia I believe or that’s what it said. Read this from WiKI:  ATM SafetyPIN software is a software application that would allow users of automated teller machines (ATMs) to alert the police of a forced cash withdrawal by entering their personal identification number (PIN) in reverse order.^[1] The system was invented and patented byIllinois lawyer Joseph Zingher (U.S. Patent 5,731,575). Contrary to a widely circulated hoax (see below), the system is not implemented in ATMs presently.

History[edit]

The concept of an alternative emergency PIN system, or duress code, for ATM systems has been around since at least July 30, 1986, when Representative Mario Biaggi, a former police officer, proposed it in the U.S. Congressional Record, pp. 18232 et seq. Biaggi then proposed House Resolution 785 in 1987 which would have had the FBI track the problem of express kidnappings and evaluate the idea of an emergency PIN system. HR785 died in committee without debate.

Zingher has not been successful in marketing his invention.^[2] Police in New York, New Jersey, Ohio, Illinois, and Kansas have supported the concept.^[3][4][5][6] Police support prompted the Illinois legislature to pass a law making it mandatory on all ATMs in Illinois. The law was changed shortly after it was passed by a "follow-on" bill that changed the meaning to the exact opposite of what they were seeking.^{[7][8][9][10]}

In 2006, an e-mail chain letter hoax circulated that claimed a reverse PIN duress code system is in place universally.^[11] American Banker reported on January 2, 2007 that no PIN-reversal duress code is used on any ATM as of that date. In September 2013 the hoax was still circulating in Australia with the text:

If you should ever be forced by a robber to withdraw money from an ATM, you can notify the police by entering your PIN in reverse. For example if your PIN is 1234 then you would put in 4321. The ATM recognizes that your PIN 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 broadcast on TV and it states that it is seldom used because people don't know it exists. Please pass this along to everyone possible. Australian Federal Police. AFP Web site: http://www.afp.gov.au

The same kind of e-mail chain letter hoax is still circulated on Tumblr and Facebook, as well as in India and other parts of the world.

Were the system implemented, PINs that are reversible such as 5555 or 2112 then would be unavailable so that false alarms would not occur. Moreover, PINs that are semi-reversible such as 5255 or 1241, where the first and last numbers are the same, would be something to avoid as well so that accidental alarms would not be triggered by mistakenly switching the middle numbers.

Diebold, a manufacturer of ATMs, states on their website that no such emergency alerting system is currently in use. They cite an article in the St. Louis Post-Dispatch which claims bankers oppose the reverse-PIN system out of concerns that "ATM users might hesitate or fumble while trying to enter their PINs backwards under duress, possibly increasing the chances of violence." Diebold further states that they would be willing to support such technology if their customers (presumably banks) request it.^[11]

Thank WIKI again…….

It sounds like a great idea.I've never heard of it but I will be telling everyone I know about it.

The rules in my family are you never go to an ATM alone.Always take backup.There are other ways to withdraw cash (in this country anyway).You can always get cash out at a filling station or supermarket checkout.A lot of the late night bars will give you cash out at their eftpos machines as well.
