About ATMs

An automated teller machine or automatic teller machine (ATM), also known as an automated banking machine (ABM) in Canada, and a Cashpoint (which is a trademark of Lloyds TSB), cash machine or sometimes a hole in the wall in British English, is a computerized telecommunications device that provides the clients of a financial institution with access to financial transactions in a public space without the need for a cashier, human clerk or bank teller. ATMs are known by various other names including ATM machine, automated banking machine, and various regional variants derived from trademarks on ATM systems held by particular banks. On most modern ATMs, the customer is identified by inserting a plastic ATM card with a magnetic stripe or a plastic smart card with a chip, that contains a unique card number and some security information such as an expiration date or CVVC (CVV). Authentication is provided by the customer entering a personal identification number (PIN).
