Introduction
An Automated Teller Machine (ATM) is a computerized device that provides bank customers with access to financial transactions in a public space without the need for a human clerk or bank teller. ATMs enable customers to withdraw cash, check account balances, transfer funds, and access other banking services anytime.
Historical Context
ATMs first appeared in the 1960s, changing the landscape of banking forever. The concept can be attributed to Luther George Simjian, who created the Bankograph in 1960, and John Shepherd-Barron, who is often credited with inventing the modern ATM, introduced in 1967 by Barclays Bank in London. The early ATMs were rudimentary compared to today’s sophisticated machines, yet they marked the beginning of a new era in banking automation.
