Does Xiaomi MIX FOLD 2 support offline fingerprint unlocking?

Nowadays, most mobile phones have fingerprint unlocking function, which can be divided into different forms. The most commonly used ones are the side fingerprint unlocking and the off screen fingerprint unlocking. Xiaomi MIX FOLD 2, as the second generation folding screen mobile phone launched by Xiaomi, has a new shape and powerful configuration, which makes many users excited. Although the price is high, it is reasonable as a folding screen. Does this phone support offline fingerprint unlocking?

Does Xiaomi MIX FOLD 2 support screen fingerprint identification? Does Xiaomi MIX FOLD 2 have fingerprint identification

Xiaomi MIX FOLD 2 uses ultra narrow side capacitance fingerprint identification technology and does not support offline fingerprint unlocking.

Capacitive fingerprint recognition is much more complex than optical fingerprint recognition. Its principle is to integrate pressure sensor, capacitance sensor, thermal sensor and other sensors into a chip.

When the fingerprint is pressed on the surface of the chip, the internal capacitance sensor will form a fingerprint image based on the charge difference (or temperature difference) generated by the peak and trough of the fingerprint, and then match it with the fingerprint library inside the mobile phone to complete fingerprint identification.

Xiaomi MIX FOLD 2 does not support offline fingerprint unlocking technology, but uses the domestic side fingerprint unlocking mode. Considering that this mobile phone has a folding screen and an ultra-thin body, it is not suitable to add a fingerprint unlocking system under the screen. At this time, the side fingerprint is also a very good choice.
