At Xiaomi crowdfunding, there is an automatic door lock that can be opened in four different ways: by entering a digital code, by a fingerprint, through an application on a smartphone, and using a regular key.

The keys of the code are touch sensitive and always active. The fingerprint scanner is located on the inside of the outer handle and is invisible to outsiders. To open the door with it, you just need to grab the top of the handle - the finger will fall directly on the sensor.

The door can be opened with one touch of a finger. However, it can also be done without touching the handle at all. This will require the mobile application of the Mijia smart home, through which the smartphone in close proximity to the door will connect to the lock via Bluetooth.

All smart stuffing of the lock is protected from any hacking and electromagnetic effects. Fingerprint codes and data are securely encrypted using a separate chip inside. In the case of a hacking attempt, an alarm will be sent to the smartphone as a message.

For the autonomy of all these functions, two lithium batteries come with a capacity of 5000 mAh each. They are used alternately and charged separately from the lock. In standby mode, from one such battery lock will work for 5 months.

In case of emergency, when you did not have time to replace the dead battery, you can power it through the USB connector from the bottom.

Such a lock is suitable for doors with a thickness of 4 to 12 cm. It costs 1,699 yuan. Sales will begin on July 10, 2019.
