Your Atm Has 4-Digits. Why?

Ever perplexed why most ATM pin have only four digits? Wouldn’t it be
more intellectual if the PIN was longer for security purpose and tough
to guess for others? Just like our long and hard email passwords as they
are 6 letters or more. Well, Scottish inventor John Adrian
Shepherd-Barron, the man who pioneered the development of the ATM
machine, had also proposed a 6-digit PIN.

John Adrain, Inventor of Atm

Barron, born in Shillong, son to a Wimbledon ladies doubles champion
Dorothy Barron, was very creative and innovative since childhood. Let’s
talk about the history of Automated Teller Machines (ATM) which is
operational since 1967. ATM have been around for 5 decades now one of
the most commodious inventions till date. ATMs are now installed across
the globes, making it super convenient for those who have debit or
credit cards. A simple and silly to withdraw money anytime, anywhere.
But if a burglar or thief steal your card, the only wall securing your
money is your 4-digit ATM PIN. But, for a hacker, this is quite easy,
isn’t it? Then why ATM pins have only 4-digit code.

Why ATM pins have only 4-Digit Code?

Scot’s wife Caroline rejected the longest string of numbers and the
idea of the 6-digit PIN as funnily she could only remember the numbers
up to four.Reportedly, 6 numbers stringed together were too much
information for her to recall. There are some banks that provides 6
digit PINs for more safety purposes, shouldn’t those of us using 4 digit
PINs be thanking the woman?
