Have You ever wondered why ATM pin consists of only 4-digits ?

Here’s The Answer:

*.John Adrian Shepherd-Barron, the inventor of ATM machine was born to Dorothy Barron (Wimbledon Ladies Double Champion) in Shillong.

*.Barron proposed a 6 digit PIN.



*.But this idea has to be rejected because of Barron’s wife Caroline.

*.This is because Caroline could remember only the largest string of 4-digits.

*.6-digit was too long for her to recall.
But now there are many banks that are offering a 6-digit PIN code for accessing the Debit cards. Sometimes we may even forget the 4-digit code.

Just imagine what happens if the PIN was 8 digits like that of passwords for emails,social media accounts etc.
So let’s  thank that woman.... :))))
