The term "Automated Teller Machines," commonly referred to as ATMs, are electronic devices that provide customers with access to financial transactions without the need for human assistance. These machines allow users to perform various banking operations such as withdrawals, deposits, transfers and balance inquiries by entering their personal identification numbers (PIN) or using other forms of authentication. The first ATM was introduced in 1967 by Barclays Bank in London, England, and since then they have become a common feature at banks and financial institutions worldwide.
