The operation of an ATM is supported by sophisticated technology.
- The machine’s card reader identifies account information from the magnetic strip or chip on the card.
- Secure network connections ensure real-time communication with banks for transaction authorization.

Modern ATMs offer a range of services beyond cash withdrawals. These include depositing cash or checks, transferring money between accounts, paying bills and obtaining account statements or balance details.
Some ATMs also offer services like currency exchange or the purchase of financial products.
Security Measures in ATMs
Security is a paramount concern for ATMs. They incorporate various features like PIN entry, encryption, security cameras and fraud detection algorithms.
Users are also advised to practice safe usage habits, like shielding the PIN entry and being aware of their surroundings.
Future of ATM Technology
The future of ATMs is evolving with advancements in technology. Upcoming trends include biometric authentication, such as fingerprint or facial recognition, contactless transactions and more interactive and personalized user interfaces. These innovations aim to enhance user experience and security.
