An Access Card is a small, portable card that allows individuals to gain entry to secure areas or systems. These cards often use technologies like magnetic stripes, RFID, or smart chips to authenticate the user. Commonly used in workplaces, schools, and public buildings, access cards help enhance security by controlling who can enter specific locations. Access cards can also store personal information and permissions, making them versatile for various applications. For example, they may be used for employee identification, time tracking, or cashless transactions in facilities like gyms or libraries. This technology helps streamline operations while ensuring safety and privacy.
