The first automated teller machine (ATM) is generally considered to have been invented and installed on June 27, 1967. The world's first retail ATM machine was opened at a Barclays Bank branch in Enfield, North London, in the United Kingdom. The invention is widely credited to the engineering team led by John Shepherd-Barron. This revolutionary device allowed customers to withdraw cash outside of normal banking hours, paving the way for the convenient banking services used across India today.
