A cash machine, also known as an automated teller machine is an electronic telecommunications device that enables the customers of a financial institution to perform financial transactions, particularly cash withdrawal, without the need for a human cashier, clerk or bank teller.

According to the ATM Industry Association (ATMIA),there are now close to 3 million cash machines installed worldwide.

On most modern cash machines, 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).
