A National Identification System (NIS) is a government initiative designed to assign a unique identification number to each citizen or resident. This system helps streamline various processes, such as voting, accessing government services, and maintaining public records. By having a standardized form of identification, it enhances security and reduces identity fraud. The NIS often involves the collection of personal information, including name, date of birth, and biometric data like fingerprints or facial recognition. Many countries implement this system to improve administrative efficiency and ensure that individuals can easily prove their identity when required.
