Biometric door lock has long been used to protect against unwanted entry. Previously, such systems were installed in the offices of large companies, but now anyone can buy this device for installation on the door of their home.
This technology allows you to open the door not with a key that is traditionally inserted into the door lock, but with your fingerprint, which is scanned and recognized by the system. This allows a person to live a comfortable and safe life.
This door lock has both advantages and disadvantages, which can be seen in the table below.
| Dignity | Flaws |
| No duplicates, no need for them. Each person's fingerprints are unique, so you don't have to worry about picking the lock. | Not a wide enough circle of the public knows about this technology, therefore, the majority is distrustful of such systems. Many people are afraid that the door lock will not recognize them and will not let them in. However, onin such circumstances, the manufacturer provides a panel for entering a pin code, as well as a traditional key. |
| There is no need to carry keychains with you, which are sometimes not only voluminous, but also quite heavy. | The lock is powered by AA batteries. This also becomes the subject of "what happens if the battery runs out?" gossip. In such a case, the manufacturer also provided a fallback option: the system is connected to the power grid, which acts as a backup power source. Some models also have an external power supply. |
| There will be no unexpected expenses if the door suddenly slams shut. | Efficiency decreases when operating at low temperatures. And if the thermometer drops below 20 degrees, then the door lock will stop working altogether. |
| Internal memory allows you to add to the database and "remember" everyone who has access. For example, bank employees, office workers, your household. There are practically no restrictions on the number. | High cost. Due to the lack of extensive mass production, the cost per lock remains quite high. |
|
Practicality and convenience. A door lock of this design contributes to the development of technological progress. |
|
| Possibility to enter multiple fingerprints for one person in case significant changes occur on the main fingerprint (deep cut,for example). | |
| Protected against vandalism and weather conditions. |
Installing this type of door lock is quite simple, but it is imperative to provide protection against possible vandalism. The principle of operation of this locking device is quite simple and clear. The finger of the person who wants to enter must be placed on a special panel with a reader. The electronic mechanism will compare your prints with those already available and make a decision. The entire comparison process takes a fraction of a second. It is a fast and efficient device designed for people's comfort.
