Reverse PIN: An ATM security measure?

Have you received this one before?

There’s an email currently circulating claiming that BPI ATMs have the capability to call the police — that is, if you were being held up, forced to withdraw money from your ATM account, and you punched in your Personal Identification Number (PIN) in reverse.

Reverse PIN to call police automatically?

First, the email:

When a thief forces you to take money from the ATM, do not argue or resist.

You might not know what he or she might do to you. What you should do is to punch your PIN in the reverse mode, i.e. if your PIN # is 1254, you punch 4521.

The moment you punch in the reverse mode, the money will come out, but will be stuck into the machine half way out and it will alert the Police (security) without the notice of the thief. Every ATM has it; it is specially made to signify danger and help. Not everyone is aware of this.

Forward this to all your loved ones, friends and those you care about.

True or not?

According to an official statement from the Bank of the Philippine Islands (BPI), this is a HOAX.

The email from the bank:

To All Employees of the BPI Group of Companies:

You may have received an email purportedly claiming that reversal of pin entry will alert police to robbery attempts via ATM. This email is an old recycled hoax email which circulated sometime in 2007. This is not true for BPI ATM machines.

Share this clarificatory statement to those you know who may have received this hoax mail.

Please be guided accordingly.

Technology exists but is not used

This technology does exist, though. There were ATMs created in the US that exactly do this. Until now, however, most banks have not used these.

Critics argue that the system fails for PINs that are identical backward and forward, for example, 5555 or 3443. True, how will the system know when to call the police if there is no “reverse” in your PIN?

Also, it was argued that even if the ATM alerts the police for a possible robbery, the thief might have already fled by the time the police arrive. ATM users are also said to be in a state of panic during a robbery or hold-up and reverse PINs might confuse them more. The thief might even be more aggressive and hurt the ATM user if no money was immediately dispensed by the ATM.

Some people may find this useful while some may not, but for now, just be informed that this reverse PIN security system in ATMs is NOT TRUE.

  1. Read this around last year at Snopes. It is true in the U.S. but hopefully they do have this feature soon in all our ATMs.

    BTW, anyone noticed that BPI did “reverse” their procedure regarding the PIN. Instead of prompting you at the start (when you put in your ATM card), you punch them right before you withdraw or do a transaction. Maybe this is a safety feature!

  2. I’ve never heard of this letter before.

    @Reel Advice, I think it’s a feature of the ATM machine. Not of the bank. Some BDO ATMs let you punch in your PIN at time of withdrawal, inquiry or payment.

    yup, I think Ive used one of those BDO atms that let you enter your pin NOT at the start of your transaction.
    Regarding the hoax article, it would still be a good idea for banks to implement such security measures (but not through a reverse PIN method, malas naman nung 5555 ang password, haha). I think it will give ATM users a sense of security when they are forced to withdraw their money by robbers. just a thought =D

  4. @Teejay – Ow okay! But all the BPI ATMs I have used recently already have a reverse procedure so maybe they opted to implement this in all of their ATMs.

    @CarloBlogg – Good point about the 55555 pin! ahaha!

  5. ofcourse its false. As a matter of fact, my pin is all 7777. So, what if this news is true? LOL! I cant imagine police coming to me everytime i waithdraw.

  6. This hoax has been circulating for years via email and text. Thanks for sharing the confirmation from BPI though.

    I think one reason why the “feature” is needed in the US is because there are ATMs with no security guards nearby. For us, there’s almost always a guard nearby. 🙂

  7. Home invasions and carjackings usually precede forced ATM
    withdrawals. This link is to an article about a very specific crime pattern
    called the “Express Kidnapping” which is basically an abduction and
    forced ATM withdrawal. It explains the details of how the crime pattern plays
    out, how to expose the data and most importantly, the details of how political
    corruption keeps the pattern from being tracked by the police. If you or
    someone you know was the victim of such a crime, read this and share it with
    everyone you know. Then send it to your local newspaper, news station, banker and
    legislator. Get them to investigate it. This applies worldwide, not just in the
