Personal Identification Number (PIN)

Date of origin: 1966
Author/inventor/context: James Goodfellow, UK Patent No.1,197,183 – 2 May 1966. John Shepherd-Barron, inventor of the Automated Telling Machine, 1966.

First used at the Enfield branch of Barclay’s Bank in 1967, with mildly radioactive cheques, serving the purpose that would later be filled by a bank card, the PIN is characterized in terms of its four-digit length by being that of the numbers that could, in an experimentally significant sense, be reliably remembered by Mrs Shepherd-Barron.
