A Brief History of the ATM
The cash dispenser was born almost 50 years ago, in 1967. For many, this was the first tangible evidence that retail banking was changing; the introduction of the ATM marked the dawn of contemporary digital banking.
The ATM finds its origins in the 1950s and 1960s, when self-service gas stations, supermarkets, automated public-transportation ticketing, and candy dispensers were popularized. The first cash machine seems to have been deployed in Japan in the mid-1960s.
The most successful early deployments took place in Europe, where bankers responded to increasing unionization and rising labor costs by soliciting engineers to develop a solution for after-hours cash distribution. This resulted in three independent efforts, each of which entered use in 1967: the Bankomat in Sweden, and the Barclaycash and Chubb MD2 in the U.K.
