3. Fraud detection: ATMs have sophisticated fraud detection systems that can detect abnormal usage patterns, such as repeated attempts to withdraw large amounts of money.

4. Encryption: ATM transactions are encrypted using advanced encryption standards to protect users' financial information from being intercepted by hackers.

5. Camera surveillance: ATMs are equipped with cameras that capture images of users who are attempting to withdraw money or make transactions.

6. Physical security: ATMs are often housed in secure enclosures or protected by security guards to prevent unauthorized access.

7. Transaction limits: ATMs limit the amount of cash that can be withdrawn in a single transaction or in a day, reducing the risk of loss in case of theft or skimming.

8. Alert systems: Some ATMs send real-time alerts to financial institutions or users themselves, notifying them of any suspicious activities or unauthorized access attempts.
