A common, if redundant, term for an Automated Teller Machine (ATM)—a self-service kiosk that lets you withdraw cash, check balances, and handle basic banking without a human teller. Ubiquitous since the 1970s, these 24/7 marvels revolutionized personal finance but are now evolving into contactless hubs amid the rise of mobile banking. The 'machine' tag is superfluous since ATM already spells it out, yet it persists in everyday lingo.
