When the fingerprint machine is used as the reading head, sometimes the door can be opened normally, and sometimes the fingerprint machine is passed, but the door is not open.
You switch the entry and exit ports, and then open our device management software - "real-time monitoring" to check whether there is any data display. If there is a connection or permission problem; If no, check whether the voltage of the device is normal. If the voltage is normal, check whether there is strong current interference in the wiring.
