The fingerprint recognition function is used almost every day for consumers who buy
fingerprint locks. The more popular ways to place the fingerprint recognition module on smart phones are divided into front fingerprints and rear fingerprints. A few mobile phones will also use fingerprints. The recognition module is placed on the side, and now a mobile phone with in-screen fingerprint recognition that can be mass-produced has been developed. ▲ In-screen fingerprint recognition mobile phones are similar to smart phones. Smart locks are also very different in the area where the fingerprint recognition module (hereinafter referred to as 'fingerprint head') is placed. These smart locks are also used in different ways because of the difference in fingerprint heads. There is a big difference. This article will count and analyze the types of smart lock fingerprint head placement and their respective advantages and disadvantages. Let's start with the more common ones: 1. The fingerprint head is exposed independently. This kind of smart lock is more common in the past, but it is relatively rare now. The common reason in the past was that fingerprint recognition was still a new thing at that time, and manufacturers would definitely inform customers of fingerprint recognition as a sales feature, and some customers would definitely pay after seeing fingerprint recognition as a 'high-tech' The desire to buy money. As for the reason that is rare now, it has been tested by time, which proves that the fingerprint head is not an indestructible module, and it needs to be covered at ordinary times. However, compared with the smart lock with a fingerprint head protective cover, there is one less action that needs to be opened, which is more convenient. Second, the fingerprint head is independent. There is a protective device. Nowadays, many manufacturers have realized that the fingerprint head is relatively fragile, so they have added a protective cover to the fingerprint head. Some fingerprint locks cover the entire input panel with a sliding cover, so that the fingerprint head and password panel can all be hidden under the same protective cover. It can not only protect these two relatively fragile parts, but also make the smart lock look neater overall after closing the slide cover. The obvious disadvantage of the sliding cover design is that it requires two-handed operation during identification: open the protective cover with one hand, and perform fingerprint identification or password input with the other. And when installing, pay attention to leaving a certain amount of space for the open sliding cover. Moreover, the sliding cover is a mechanical part, and the service life must be scrupulous. 3. The fingerprint head is hidden at the shaft of the handle. Many people are looking for the most convenient way to place the fingerprint recognition head in the smart lock. In fact, this method is relatively easy to find, because this position is usually held by a human hand. (Such as a door handle) at a fixed position. If the fingerprint head is hidden at the handle shaft, when the hand is holding the door handle naturally, the thumb will naturally be pressed on the fingerprint head, so that the door handle can be directly turned to open the door. ▲ The smart lock with the fingerprint head hidden in the door handle, but this way of placing the fingerprint head can perform fingerprint recognition in the most natural experience. The door can be opened immediately after identification, and the left and right hands can be easily unlocked without picking up fingers. The above three ways of placing the fingerprint head are relatively common. In addition, many smart lock manufacturers also have unique ideas in hiding fingerprint heads. For example, in the push-pull door opening method, some manufacturers hide the fingerprint head behind the push-pull handle. Although the fingerprint head is hidden in this way, the power consumption is a bit high. There are many smart locks that have the door open method. Own characteristics, for example, some manufacturers put their smart locks directly on both sides of the lock cylinder. When opening the door, you only need to turn it like a spherical handle lock to open the door smoothly. The fingerprint recognition module is hidden on the door handle and can be recognized when the door handle is held. The 'spherical handle' smart lock places the fingerprint head around the lock. The smart lock transforms the way of opening the door from a key to a fingerprint and a password, allowing residents to 'carry' the key with them without worrying about losing it. And smart lock manufacturers will continue to optimize the way people open the door when designing, so that residents can open the lock more naturally and conveniently.
