The conversion unit converts the optical signal into an electronic signal. The controller compares the electronic signal with the data in the database, and if the comparison matches, controls a brake to open a switch or access control system.

The optical signal is a light sequence signal composed of a light dot matrix signal or a light and dark pulse wave.

The conversion unit is a photodiode or a photodetector.

Or the conversion unit includes a plurality of photodiodes or a plurality of photodetectors arranged in a matrix.
