Observing people using their Personal Identification Numbers (PINs) with their debit and credit cards is typically categorized as: Shoulder surfing
How to explain
Shoulder surfing involves the act of surreptitiously observing or watching individuals as they enter their PINs or sensitive information on devices like ATMs or point-of-sale terminals.
This method does not involve hacking into systems, dumpster diving for physical documents, or utilizing phishing techniques online. Instead, it relies on visual observation or surveillance to obtain confidential information, potentially leading to identity theft or unauthorized access to financial accounts.
Implementing caution and privacy measures while entering PINs in public areas helps prevent shoulder surfing attacks.
