SIM controller, German SIM model, SIM price

The SIM controller is the core of the access control system, the system brain that manages entry and exit channels. It has evolved from traditional door locks. The door controller is an access control product that integrates card reading and control, available in standalone and networked versions. Simply put, the access controller is a device that integrates the access control board and card reader; higher-end models also include a keyboard and display. It can be used as a complete access control system by simply connecting the power supply. For a single door, if entry is by card swipe and exit is by button press, the controller can connect to only one card reader per door.
