Cash Machine Celebrates 40 Years

Yep, last month the cash machine turned 40 years old. The first cash machine was located north of London, and it used carbon 14 checks, a mildly radioactive substance — not a plastic credit card. When initially installed, the cash machine, invented by John Shepherd-Barron, would dispense up to 10 pounds UK.
