Who are these guys?

there is a picture below who are inventing the automated teller machine. An automatic teller machine or ATM allows a bank customer to conduct their banking transactions from almost every other ATM machine in the world. As is often the case with inventions, many inventors contribute to the history of an invention, as is the case with the ATM. Read each page of this article to learn about the many inventors behind the automatic teller machine or ATM.

However, some experts have the opinion that James Goodfellow of Scotland holds the earliest patent date of 1966 for a modern ATM, and John D White (also of Docutel) in the US is often credited with inventing the first free-standing ATM design. In 1967, John Shepherd-Barron invented and installed an ATM in a Barclays Bank in London. Don Wetzel invented an American made ATM in 1968.

However, it wasn't until the mid to late 1980sthat ATMs became part of mainstream banking.

Luther Simjian came up with the idea of creating a "hole-in-the-wall machine" that would allow customers to make financial transactions. In 1939, Luther Simjian applied for 20 patents related to his ATM invention and field tested his ATM machine in what is now Citicorp. After six months, the bank reported that there was little demand for the new invention and discontinued its use.

John Shepherd Barron - PIN Numbers

The idea of a personal identification number or PIN was thought up by John Shepherd Barron and refined by his wife Caroline, who changed John’s six digit number to four as it was easier to remember.

In 1967, a bankers' conference was held in Miami with 2,000 members in attendance. John Shepherd Barron had just installed the first ATMs in England, and was invited to talk at the conference. As a result, the first American order for a John Shepherd Barron ATM was placed. Six ATMs were installed at the First Pennsylvania Bank in Philadelphia.

In a Barclays press release, the bank stated that comedy actor Reg Varney, star of TV sitcom "On the Buses", became the first person in the country to use a cash machine at Barclays Enfield on June 27th 1967 (see photo). The ATMS were at that time called DACS for De La Rue Automatic Cash System. John Shepherd Barron was the managing director of De La Rue Instruments, the company which made the first ATMS.
