Definition
A Personal Identification Number (PIN) is a secret numeric code assigned to a cardholder of a cash card, credit card, or multifunctional card. This number is crucial for authenticating the cardholder’s identity during transactions at automated teller machines (ATMs) and while utilizing electronic funds transfer at point of sale (EFTPOS) systems. Unique to the cardholder and shrouded in secrecy, the PIN is a formidable barrier against unauthorized access, ensuring that lost or stolen cards cannot be easily exploited.
Importance in User Security
PINs add an essential layer of security, functioning as an electronic signature that only the cardholder knows. This not only protects the cardholder from financial pilferage but also reduces the risk of identity theft. Think of it as a numerical watchdog that barks (or locks down) when strangers (or thieves) try to access your precious monetary vault.
