Keycards are plastic cards embedded with magnetic strips or electronic chips used as a secure method of access control. Commonly used in hotels, office buildings, and secure facilities, keycards allow authorised users to unlock doors or gain entry to specific areas. They offer advantages over traditional locks including the ability to quickly revoke access, create audit trails, and change access permissions without physical key changes. Keycard systems are a standard security feature in modern buildings.
