In autumn and winter, when the weather is cold after the season, the moisture in the air will become less, and the humidity of the air will become smaller, so the colder air is the drier, and the dry finger surface is very unfavorable to the collection of fingerprint images.
Doing a good job of keeping your hands warm, often applying some hand cream to keep them moisturized, and wearing gloves to avoid fingerprint wear when doing heavy work will improve the speed of fingerprint recognition.
In case of emergency or insufficient conditions, you can choose other unlocking methods such as password, card, and key to enter the house first.
