At that time plastic ATM cards did not exist. John Shepherd Barron's ATM machine took checks that were impregnated with carbon 14, a slightly radioactive substance. The ATM machine would detect the carbon 14 mark and match it against a pin number. Shepherd-Barron credited his wife with the idea for a four-digit PIN code after first toying with the use of a six-digit security code. He told the BBC: "Over the kitchen table, she said she could only remember four figures, so because of her, four figures became the world standard." He did not patent his system and did not make any money from his invention.There are now more than 1.7 million ATMs across the globe, according to the ATM Industry Association.
