An elevator card is a digital or physical card used for access control in elevators. It allows authorized individuals to access specific floors or areas within a building by simply tapping or swiping the card at the elevator panel. Typically used in commercial buildings, hotels, or office spaces, elevator cards enhance security by restricting access to certain floors, ensuring only authorized users can reach sensitive areas. These cards often work in conjunction with other access control systems, such as RFID or magnetic stripe technology, offering a seamless and efficient method of managing building access.
