1. Strong environmental adaptability

2. Longer lifespan

3. Lower cost

1. Strong environmental adaptability. The collection window of the optical fingerprint recognition module is generally made of tempered glass, which can withstand pressure, wear, acid, alkali, and stain corrosion to a certain extent. It has good temperature adaptability to the working environment, with a suitable range of -15 degrees Celsius to 55 degrees Celsius and humidity between 20% and 95%. The glass surface is easy to clean and can be used in both ordinary environments such as homes and special environments such as humidity, high temperature, and dust.

2. Longer lifespan. When using the capacitive fingerprint module, the finger will directly press onto the recognition module, even if there is a sapphire glass in between, the finger will directly press onto the recognition area. When using the optical fingerprint recognition module, the finger only presses on the glass, and then the fingerprint image is read by a CCD (a device similar to a mobile phone camera, but not as complex as a mobile phone camera). There is no contact in the middle, so there will be no crushing situation.

3. Lower cost. Compared to semiconductor fingerprint modules, optical fingerprint modules have lower costs.
