It’s been more than 50 years, these Automated Teller Machines or ATM have come into our lives and so to say, it has made our lives most convenient ever.
The ATMs installed now at every foot step, can provide you money anywhere, anytime with a simple and single swipe. You require cash, find an ATM machine nearby, swipe your card and enter your 4-digit ATM PIN.
But during all this, have you ever thought WHY THERE ARE ONLY 4-DIGITS IN THE ATM PIN?
Why isn’t there a longer PIN may be of six digits that can be more hard to guess?
His idea to keep a 6-digit PIN for ATM cards was rejected because Scot’s wife Caroline was not able to remember a 6-digit code. The longest string of number that Scot’s wife was capable of remembering is four.
Reportedly, 6 numbers stringed together were too much information for her to recall. This made Scot to keep 4-digit Pin of ATM cards.
So, those who feel hard even to remember your 4-digit pin, please be thankful to woman. If there has been no woman in Scot’s life, your ATM pin might have been longer and so is your trouble remembering it.
