Day +560 : Entering ATM pin in reverse to call police?

I am fine today.

I received an email from one of my nephews with the following forwarded message:

“Sekiranya anda dirompak dan dipaksa untuk mengeluarkan wang akaun anda daripada mesin ATM...anda boleh meminta bantuan cara senyap denganmemasukkan no Pin anda di mesin ATM cara terbalik........

Sebagai contoh jika no Pin anda adalah 123456, jadi anda harus memasukkan nombor 654321......

Mesin ATM akan mengenalpasti nombor tersebut adalah nombor yg diterbalikkan drpd nombor yg sebenarnya melalui kad anda yg masukkan kedalam mesin tersebut......

Mesin ATM akan tetap mengeluarkan wang tunai seperti biasa, tapi apa yg kita tidak ketahui, pihak Bank dgn segera akan menghantar pihak berkuasa (Polis) kepada anda....

Perkara ini pernah disiarkan di TV baru-baru ini dan ianya menyatakan kaedah ini jarang diguna disebabkan ramai orang tidak mengetahui akan kewujudan sistem yg seumpama ini.....

Sebarkanlah maklumat ini seluas mungkin untuk manfaat kepada orang lain....”

Or in English the message should read:

“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 123456 then you would put in 654321. 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.”

My nephew asked me whether this is true. I did a test on the ATM machine and get a “wrong pin number” message :-) So no money will be delivered to you and no police will be called. This message is simply another email hoax. Please don’t forward it if you receive one.

Though it is a hoax, the idea is quite brilliant. It is very common for the car hijackers to force their victims to reveal the ATM pin. As written on my blog Day+ 244 (Government & robbers, who is more efficient?), my friends experienced this last year. If this system was in place, the hijackers would already be caught.

However, one important issue needs to be addressed in implementing this system. It is for those who uses symmetrical password such as 123321; reversing the password bears no different to the original one in this case :-( So the system would not know whether you are in trouble through the password.

If the programmer overlooks this issue, then you would be caught by police every time you withdraw money using the symmetrical password :-(

See you next post :-)

Hi sir,

Maybe the ATM machine has to be in a room and we need to use the ATM card in order to enter the room. The room has to be monitored by the security camera and provided with emergency button which will lock the door.

With this, I believe the robber will just kill you rather than asking you to withdraw money :p

SzuKiak,

The problem is that the robber will force you to reveal the ATM pin and then he will enter the room to withraw the money. He won't be stupid enough to press the button to lock himself inside the room :-)

If the reverse pin system is in place, we can tell the robber the ATM pin number in reverse, then even if the robber withdraw the money himself, he will be caught.

Ya loh! Just give them all the money and keep our life :-)
