Since yesterday I have seen this hoax once again being passed around Facebook.
The gist is this:
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.
While this sounds like a good idea it is NOT real.
Think about a pin that is not reversible, something like 6446.
Of course if this system was real banks would have to force everyone to re-establish their pin numbers so that a reversible pin could be established.
According to Wikipedia there is such technology available since 1986, however there has never been an implementation.
Of course Snopes has the disputing evidence too, but it seems that people just don’t take the time to research if something really is real before just passing it on.
Sorry if you were one to pass this hoax on.
Are there any other hoaxes that you see currently floating around the social web? Let me know in the comments below.
