This dreamy story begins with an Englishman named John Adrian Shepherd-Barron, who was suddenly struck by an idea. He was thinking about the hassle of fixed banking hours for withdrawing cash because, one day, he had gone to his bank and returned frustrated after being refused the chance to cash his cheque as the bank had already closed. He was inspired by chocolate vending machines.
According to Shepherd-Barron: “It struck me there must be a way I could get my own money anywhere in the world or in the UK. I hit upon the idea of a chocolate bar dispenser, but replacing chocolate with cash.”
Serendipity is often described as the knack for making lucky discoveries by accident. At the time, Shepherd-Barron was the Managing Director of De La Rue Instruments, a company focused on security printing and paper-based systems in Basingstoke, England.
The word itself was actually coined by Horace Walpole in 1774. He took inspiration from a Persian fairy tale called The Three Princes of Serendip, in which the characters were constantly stumbling upon wonderful things they were not even looking for. “Serendipity” is actually rooted in “Serendip”, which is an ancient name for Ceylon — the island we now know as Sri Lanka.
Some of the most useful discoveries in history started as nothing more than a sudden spark of inspiration. Back in 1907, a Belgian scientist named Leo Baekeland was trying to find an alternative to shellac, an expensive resin made by an Asian beetle. Instead, he ended up inventing the world’s first heat-resistant plastic, which was later named “Bakelite” in his honour.
History is full of these “happy accidents”. Perhaps the most famous was when Alexander Fleming noted: “When I woke up just after dawn on September 28, 1928, I certainly didn’t plan to revolutionise all medicine by discovering the world’s first antibiotic, or bacteria killer. But I suppose that was exactly what I did.”
His discovery led to the official announcement of penicillin on March 7, 1929 — a marvellous breakthrough that has saved billions of lives worldwide. History is full of stories like these that completely changed the course of human life.
Returning to Shepherd-Barron, he shared his idea with the head of Barclays Bank in London, England, who gave it serious thought. It was a massive undertaking that deserved real attention, and it eventually laid the foundation for branchless banking. This transformed daily life for millions of people across our global village.
It has been nearly 59 years since the first cash machine, called ‘Barclaycash’, was installed on June 27, 1967, outside a Barclays Bank branch in Enfield, North London. A plaque near the machine is inscribed with: “The world’s first cash machine was installed here on 27 June 1967,” along with the tagline: “lives made much easier.”
The first person to ever withdraw cash from it was actor and comedian Reg Varney. In that moment, a dream came true and an incredible historical landmark was born.
Thus, the ATM changed the entire banking scenario with a big bang, as customers who wanted to withdraw money after banking hours no longer had to depend on bank branches and fixed timings, but were able to do so anytime and anywhere through ATMs.
There is also a very interesting incident relating to the evolution of its password, also known as the PIN (Personal Identification Number). In the beginning, a six-digit PIN was proposed. Shepherd-Barron discussed the matter with his wife, Caroline, but noted that she could remember only four digits. As a result, four-digit PINs were selected and, with the increase in ATMs, this became the recognised standard all over the world.
The mathematical lapse of Caroline resulted in ease for ATM users everywhere.
