A national identification card is an official document issued by a government to its citizens. It serves as proof of identity and often includes personal information such as name, date of birth, and a unique identification number. These cards can be used for various purposes, including voting, accessing government services, and verifying identity in everyday situations. Many countries have implemented national identification cards to enhance security and streamline administrative processes. The cards may also include biometric data, such as fingerprints or facial recognition, to improve accuracy and prevent fraud. Examples of such systems can be found in countries like India with its Aadhaar card and Germany with its Personalausweis.
