How Do POS Terminals, Automated Teller Machines, and DVD Kiosks Work? A terminal is a computer, usually with limited processing power, that enables users to send data to and/or receive information from a host computer. POS terminals, ATMs, and DVD kiosks are special-purpose terminals. A POS (point-of-sale) terminal records purchases, processes credit or debit cards, and updates inventory. An automated teller machine (ATM) is a self-service banking machine that connects to a host computer through a network.
