Does Xiaomi 13 support fingerprint unlocking
As the functions of mobile phones become more and more perfect, fingerprint unlocking mobile phones have become the standard configuration of all smart phones, allowing users to directly unlock mobile phones without entering passwords. It is not only much convenient, but also much better than password unlocking in terms of security and privacy protection. So, as the upcoming new mobile phone, Xiaomi 13, does it have fingerprint unlocking function? Interested partners, come and have a look!

Capacitive fingerprint identification is the earliest fingerprint identification technology. It mainly uses the silicon wafer to contact with the electrolyte on the skin to form an electric field. The sensor can record the uneven shape on the fingerprint for users to unlock. In principle, capacitive fingerprint recognition requires a medium to conduct, which is simply a key like thing to carry. In the era of full screen, mobile phone manufacturers designed it as post fingerprint unlocking or side key fingerprint unlocking. At the same time, this fingerprint unlocking requires high finger dryness, and it is impossible to unlock the mobile phone when the hand is wet. Therefore, there are few mobile phones using this technology on the market today.
Optical fingerprint identification is a popular fingerprint unlocking technology nowadays. Compared with capacitive fingerprint identification, this fingerprint identification technology is a leap forward. It moves the fingerprint to the screen, saving the space of the mobile phone. Its principle is very simple, mainly using the reflection and refraction of light. When the finger is pressed on the screen, the screen will emit bright light to illuminate the fingerprint, which will be transmitted to the sensor under the screen for identification through reflection and refraction, thus realizing fingerprint unlocking.
Ultrasonic fingerprint identification is a relatively new fingerprint identification technology. Its principle is mainly based on the pressure reading of the reflected sound wave from the skin, so as to draw the fingerprint sound wave, which can be unlocked after the transmitter is identified. In principle, compared with the first two fingerprint unlocking technologies, the ultrasonic fingerprint identification technology uses three-dimensional input and acoustic wave transmission, which does not require very high finger details. Therefore, the phone can be unlocked even when the hands, fingers are stained or even the screen is wet, and the sensitivity is not affected at all.
The above is the introduction of 13 Xiaomi phones that do not support fingerprint unlocking. As the latest flagship model of Xiaomi, it must have fingerprint unlocking function. In addition, according to the current information, this phone also supports ultrasonic fingerprint unlocking technology, which can identify faster and more accurately!
