When did the first ATM open?

The worlds first automated teller machine opened to the public on 27 June 1967 at Barclays Bank in Enfield. It was devised by John Shepherd-Barron, who reportedly had the idea after missing bank opening hours. Early machines did not use plastic cards with magnetic stripes; instead customers used special paper vouchers coded with a mildly radioactive substance and entered a personal number. The maximum withdrawal was modest, but the concept of round-the-clock cash access quickly caught on. Within a few years machines using magnetic-stripe cards spread across the world and transformed everyday banking.
