Fingerprint recognition technology has gone from being little known in the past few years to gradually being familiar with it, and now it has entered thousands of households. Fingerprint recognition has taken on the "heavy task" in life.
Fingerprint refers to the convex fingerprint on the front skin of the end of a human finger. Due to its long-term invariance, independence and convenience, it has almost become a synonym for biometric identification. Fingerprint recognition technology involves image processing, pattern recognition, computer vision, mathematical morphology, wavelet analysis and many other disciplines. Do you think that mobile phone fingerprint recognition can only be used to unlock? No, no, no, it can also encrypt applications and data, handle pull-down notifications, selfie functions and more. I have to go home and try it out.

However, the home button and other fingerprint identification buttons of smart phones have different colors. How are they colored? Let us tell you! Simply put, it is to paint ink on a specific glass, and then paste the glass on the chip for coloring. So is your home button color clear? The Colorimeter will tell you!
Use the Spectrophotometer CS-660 to measure it. Connect to the computer and open the color quality management software for testing.
