3. Lower cost
1. Strong environmental adaptability. The collection window of the optical fingerprint recognition module generally adopts toughened glass, which can resist pressure, abrasion, acid and alkali, and corrosion to a certain degree. It adapts well to the temperature of the working environment, the applicable range is -15 degrees Celsius to 55 degrees Celsius, the humidity is between 20%-95%, and the glass surface is easy to clean. It can be used in ordinary environments such as households, and can also be used in humidity, high temperature and dust. And other special environments.
2. Longer life span. When the capacitive fingerprint module is in use, the finger will directly press on the recognition module, even if there is a sapphire glass in between, the finger will directly press on the recognition area. When the optical fingerprint recognition module is in use, the finger is only pressed on the glass, and then the fingerprint image is read by a CCD (a device similar to a mobile phone camera, but not as complicated as a mobile phone camera). There is no contact in the middle, so there will be no crushing situation.
3. Lower cost. Compared with the semiconductor fingerprint module, the optical fingerprint module has a lower cost.
