Biometric information authenticating device, and biometric information authenticating system

A biometric information authenticating system, comprising:

• a start switch device comprising a biometric information sensor to detect contact of an operating finger with a reading surface and to read biometric information of the operating finger, an illumination unit comprising at least one light source, and a control unit to control the illumination unit by an illumination pattern including a combination of turning on and off of the at least one light source;
• and
• a vehicle control unit electromagnetically connected to the start switch device and each unit of a vehicle,
• wherein the vehicle control unit determines the state of the vehicle and outputs vehicle information to the control unit based on a detection result of contact of the operating finger with the reading surface, status of reading of the biometric information, operation status of the vehicle, and start status of a drive system, and the control unit controls the illumination unit to produce the illumination pattern corresponding to the vehicle information.
