ATM Full Form, Features & Components Explained (2026)

Automated Teller Machines (ATMs): Meaning and Basics

Automated Teller Machines (ATMs) are self-service banking terminals used to perform routine banking functions — such as cash withdrawal, cash or cheque deposit, balance enquiry, mini-statement and fund transfer — using an ATM-cum-debit card or, increasingly, card-less options like UPI QR and OTP-based withdrawal.

In India, the committee headed by Dr. C. Rangarajan recommended the setting up of ATMs to modernise the country’s payment and banking infrastructure. Today, ATMs remain a critical delivery channel even as digital banking grows, and they continue to be examined under JAIIB, CAIIB and other IIBF certifications.
