Automatic teller machines (ATMs) are ubiquitous banking devices that allow customers to conduct financial transactions without the need for a human teller. There are a variety of synonyms for ATMs, including cash machines, cashpoints, cash dispensers, automated banking machines, and automated teller kiosks. While the basic function of these machines is the same, variations in design and technology have led to the creation of different terms for them. Regardless of the name used, ATMs remain a vital component of modern banking systems and continue to evolve with advances in technology such as mobile banking and cryptocurrency.
