Advantages over keys
- A lost card is blocked, so there is no need to change the locks.
- Entry can be limited by time, for example only during working hours.
- The system records who came in and when, and can also be used for attendance tracking.
Card security
Old cards with a fixed number are easy to copy. Modern cards use encryption. When choosing a system, it matters that both the reader and the cards support secure protocols.
Integration
An access control system can be linked to an alarm (arriving disarms it), cameras and a smart home.
