Well, the idea of the 6-digit PIN was proposed by the man who pioneered the development of the ATM machine. He was born in Shillong and was son of a Wimbledon ladies doubles champion, Dorothy Barron.
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.
