What is the term for watching someone enter their PIN at an ATM?

Shoulder surfing is the term used to describe the act of observing someone as they enter their Personal Identification Number (PIN) or other sensitive information at an ATM or similar electronic device. This technique typically involves standing close enough to the individual to see the keypad or screen without their knowledge, allowing the observer to gain access to their financial accounts or personal information.

The term highlights the importance of being vigilant in public settings where personal information is being inputted, as it can lead to identity theft if the PIN is captured and misused. By understanding shoulder surfing, individuals are better equipped to protect themselves against such forms of information theft.
