The ATM machine gained Shepherd-Barron an ever-lasting recognition in the banking world and paved the way for hi-tech banking techniques, online bank accounts and PIN and chip security technology. The four-digit internationally accepted standard PIN was also invented by him. Earlier, he had a six-digit Army serial number in his mind but later his wife suggested for a shorter PIN as it would be easy to remember. Finally in 1967 that the first ATM that dispensed paper currency round the clock, was unveiled. The ATM machine installed outside a Barclay’s bank in North London started dispensing cash on a 24 hour basis.
As the plastic cards were still to have come into existence, this machine accepted and generated money through cheques impregnated with certain chemicals. Majorly a mild radioactive substance, Carbon 14 was used for detection by the machine. Once the PIN was given, the machine gave out the cash. This radioactive substance had no ill effects on the health of users and Shepherd-Barron claimed that a user would have to eat about 136,000 cheques to suffer any kind of ill-effects. Reg Varney, a famous TV sitcom popular became the first person to use the ATM in the year 1967 and withdrew about 10 dollars. The amount seems too less for us, but this money was enough for a complete night out spent on the tiles in London, inclusive of dinner, drinks, a show and a taxi-ride back to home, in short enough cash for a “Wild Weekend”.
While this prototype device originated by Shepherd-Barron had started functioning, various parallel developments were happening in different parts of the world. An American Engineer Donald Wetzel of Docutel engineered the Docuteller ATM which was declared as the first modern magstripe machine. It recognized magnetically encoded plastic (credit cards) and not the usual paper cheques.
And there have been a lot of efforts gone into final development of the ATM, the ones we see today, the ones we use so frequently, and the ones which have made our lives revolve around plastic money. The development of ATM ever since its baby steps in the late 1930s and then gearing up for longer runs in the 1960s, and finally a matured and stable stage that we see the ATMs in today. Undoubtedly, most of the ideas and patents contributed for makeover of the ATM from time to time form the backbone of what was initiated as “holes in the wall”.
Today, ATMs hold a strong foothold in the world, offering everyone a better access to their money, be it in any corner of the world. Let’s put figures to assumptions, there are about 1.8 million ATMs in use around the world with ATMs on cruise and navy ships, airports, newsagents and petrol stations. ATMs too have been categorized as on and off premise ATMs. On Premise ATMs are capable to connect the users to the bank with multi-function capabilities. Off premise, ATM machines on the other hand are the "white label ATMs" and are limited to cash dispense, no balance enquiries, no statement print-out.
The developments have not stopped; the contactless technology is on its rise. Shepherd-Barron continued to take inimitable and lively interest in technology well even in his old age and had foreseen a future where plastic cards too would be numbered. For his excellent and unforgettable contributions to financial technologies, he was also offered the OBE in the year 2005. And in the year 2010, he took his last breath and left behind his legacy of technological advancements which would refuses to end. Many more inventions are in process and many will be successful too. The time is just right to bring in the glorious inventions rolling in.
