No 2. Automatic Teller Machine (ATM)
An automated teller machine (ATM) or automatic banking machine (ABM) is a computerised 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. 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). ATMs have become a standard service of every bank over the years. This is undoubtedly one of the most successful and popular banking technology ever introduced.
