Ordinary locks use keys to open doors, and the safety factor is relatively low. This is the biggest difference between fingerprint lock and ordinary lock.

The traditional common lock is a mechanical lock, which is unlocked by pairing the key with the lock core and opening the actual lock tongue. Fingerprint lock is a new intelligent technology product that uses fingerprints and passwords to unlock. Its security is very high, and ordinary locks have great security risks.

The difference between fingerprint lock and ordinary lock

Ordinary door locks use mechanical keys to open doors, but mechanical keys are often forgotten, or easily lost, or even copied by people with ulterior motives, which brings great trouble and inconvenience to people's lives, especially security problems, which makes people uneasy.

Fingerprint lock is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. The uniqueness and non-replicability of fingerprints determine that fingerprint lock is the safest lock among all locks at present. Very convenient and easy to use. When you go back to your door, it will open. You never need to bring a key, especially for the elderly and children. It is super simple and convenient to use. After all, fingerprints are carried with you and will not be lost. Unless there is an accident, fingerprints are basically unchanged for life. It can be seen that fingerprint lock can really play a safer, more convenient and faster role than key lock.

Which is better, fingerprint lock or ordinary lock?

Key lock

Fingerprint lock and key lock have their own advantages. Let's start with the key lock. As a traditional lock, the key lock has no doubt about its safety. The traditional key lock we usually use is the most widely used lock. The key lock is usually unlocked with a key, so the safety is naturally high. Moreover, according to the different grades of key locks, the safety factor is also increasing. In other words, the higher the level, the safer the key lock! When ordinary families buy key locks, they will choose more expensive and better ones. More anti-theft.

However, the disadvantages of key lock are obvious. If you forget to bring your key home, you can't open the door. Only a professional locksmith can open the door. The price of opening a lock is not low, and if it is a class C lock, it can only be forcibly unlocked and replaced!

Fingerprint lock

As a new type of lock, fingerprint lock is very attractive to young people and people who like new things. As the name implies, the fingerprint lock is unlocked directly. Everyone's fingerprint is unique, so you don't have to worry about security after entering the fingerprint. Secondly, the fingerprint lock is convenient, so don't worry about forgetting to bring your key. Finally, there are many ways to unlock the fingerprint lock. In addition to fingerprints, it can also be unlocked with passwords and spare keys. It is convenient and practical for the elderly at home to unlock the lock with a key without fingerprints.

For the convenience and safety of family members, it is recommended to choose a fingerprint lock.

Which is safer, fingerprint lock or ordinary lock? 2. Which is safer, fingerprint lock or key lock?

Now most people will choose security doors when they choose the entrance door for decoration, and there are also various security doors on the market. In addition to traditional key locks, there are also smart locks, such as password locks and fingerprint locks. Some people think that smart fingerprint locks are safer, but many people think that traditional anti-theft locks are safer. So which two locks are safer? See what the locksmith says.

The traditional key lock we use is also the most widely used lock. The only way to open the key lock is to use the key, and the traditional anti-theft key lock is also graded. Of course, the higher the level, the higher the safety factor. In other words, the less likely it is to be damaged. When buying this kind of key lock, the average family will choose a more expensive and better one, which will be more burglarproof.

As a kind of smart lock, fingerprint lock is relatively safe and convenient to use, because it opens the door by identifying fingerprints, and everyone's fingerprints are unique and difficult to copy. At the same time, the fingerprint lock can also be opened by password, card and emergency key.

Compared with the key lock, the biggest advantage of fingerprint lock is that you don't have to worry even if you forget to bring your key when you go out. Anyway, you only need your fingerprint to open the door, but the key lock will not work. If you forget your key, you can only ask the locksmith. Generally, the key lock master will open it directly, but the class C lock will be replaced directly.

Some people will say, what if the fingerprint lock is out of power? Don't worry, the designer took it into account when designing. The fingerprint lock has an emergency key, but what if someone opens the door with a fingerprint but doesn't have a key? If there is an external power supply, of course, it is directly connected to the external power supply to temporarily unlock it! What if there is no external power supply? Then you have to find the locksmith's phone number!

In fact, to put it bluntly, the key lock and fingerprint lock are just different in opening mode, and everything else is the same. I believe everyone has heard an old saying: guard against gentlemen and not against villains. This sentence is just right for anti-theft locks. Since you can find a locksmith to help you open the door, you can't use the door of the bank vault to prevent it! So as long as you buy qualified products from regular manufacturers, they are all the same, depending on which one you use is more convenient.

Second, how to choose a lock?

1, "Consumers can make a basic judgment on the grade of the key by the number of marbles on its appearance." Now take out the keys to class A, class B and super class B locks. Generally speaking, the key of class A lock looks relatively simple, with few grooves and pits on the key, mostly in one row, while the key of class B lock looks more complicated, mostly in two rows of grooves and pits.

2. Compared with the keys of A-class and B-class locks, the keys of super B-class or C-class door locks look simpler, and their appearance is quite different from that of A-class and B-class locks. This is because this seemingly simple key contains more advanced technology, and both sides of the key are irregular grooves. Meijia to choose anti-theft lock has carried on the action:

3. Buying a lock depends on the "teeth" of the key. The more teeth, the deeper the teeth, the more complicated the arrangement, the more difficult it is to open, and the better the anti-theft performance.

4. Weigh the lock by Jin. The heavier the weight, the better the quality of the lock core. The more beads in the lock core, the better the anti-theft function.

5, choose the lock core to see the color, see the workmanship than the color. The lock core with good quality is electroplated, with smooth surface and bright color. Dark yellow is copper core, which is relatively strong and has good anti-theft performance. The lock core is dull in color, and the zinc alloy with bubbles is gray in color, so the anti-theft performance is average.

6. When the key is rotated and inserted into the lock core, the anti-theft performance is poor. After the key is half inserted, rotate five to seven components clockwise or counterclockwise, and continue to press the key into the lock. The jammed key indicates that the anti-theft performance of the lock core is poor, and the anti-theft effect is good when it is successfully inserted into the lock core in a semi-rotating state.

In fact, whether you choose fingerprint lock or key lock, the key is to look at your own needs, and you can also choose the right lock according to your installation position. Ensuring the safety of family property is also for the comfort and health of family life, so everyone must pay attention to choosing the right lock.

Which is safer, fingerprint lock or ordinary lock? 3 Is the fingerprint lock safe?

First, whether the fingerprint lock is safe depends on the accuracy of fingerprint identification.

At present, the accuracy of fingerprint identification in the industry mainly refers to two aspects, namely, the true recognition rate and the false recognition rate. The true rate refers to the probability that the fingerprint lock refuses to record the true fingerprint, while the false recognition rate is just the opposite of the true rate, that is, the probability that the fingerprint lock accepts the unrecorded fingerprint. At present, there is no minimum or maximum standard for these two probabilities in the industry, and the probabilities among enterprises vary greatly. Generally speaking, it is acceptable that the true rate and the false recognition rate are lower than 5% and 5 parts per million respectively.

This probability mainly depends on the resolution of the fingerprint identification module. At present, the industry-recognized resolution standard is 500dpi, which is the lowest standard to ensure clear identification, safety and reliability under the existing technical conditions. At present, the fingerprint lock has the highest recognition rate from the industry giant Digil, and its recognition rate is as high as 560dpi, making fingerprint imaging clearer and more accurate.

Second, whether the fingerprint lock is safe depends on the stability of electronic components.

Fingerprint lock is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. Electronic technology plays a decisive role in fingerprint lock, and its stability directly affects the security of fingerprint lock. If the electronic part is unstable, the fingerprint lock may not respond or perform other operations when you operate, ignoring your instructions.

For example, when you close the door, the electronic components are unstable and there is no instruction to lock the door, then the door is just closed and unlocked, and it can be opened with a gentle push, which is dangerous for the owner.

Thirdly, whether the fingerprint lock is safe depends on the stability of the ferrule.

The ferrule is the stress point of the whole lock and the most important part of the lock. The stability of the ferrule is the most important thing in the whole lock. If the ferrule is unstable, just a few kicks will be enough, even if the technology of fingerprint lock has reached an unparalleled height.

The stability of ferrule mainly depends on the material of ferrule. At present, there are mainly three kinds of ferrule materials in the industry, namely zinc alloy, iron and stainless steel. Zinc alloy is lighter in texture and easier to form, which is welcomed by manufacturers. But it is cheap and has high strength, so it is often used as a core insert material. Among the three materials, stainless steel is the most stable, with good anti-oxidation and anti-corrosion effects, but the cost is higher.
