Truth: At present, fingerprint acquisition technology mainly includes optical acquisition technology, semiconductor acquisition technology, and ultrasonic acquisition technology. Although the ultrasonic acquisition technology is highly technical, it is rarely used in the fingerprint lock recognition system because of its high cost and in the experimental stage. Semiconductor acquisition technology was born in 1998, which can instantly capture and adjust images in time. It is more accurate than optically acquired images, but it is easily affected by static electricity, sweat, dirt, finger wear, etc., resulting in the sensor not taking images, or even being Damaged; not wear-resistant, short life, therefore, its application range is relatively small. The optical acquisition technology is the oldest fingerprint acquisition technology. It has experienced the test of long-term practical application, can withstand a certain degree of temperature change, has good stability and is sensitive to recognition, and its collector is generally made of tempered glass, which is very wear-resistant. Effectively extend the service life. In view of the above advantages, optical acquisition has become the mainstream fingerprint acquisition technology on the market, and is widely used in the management of fingerprint locks, fingerprint access control, fingerprint punching machines, automobile fingerprint alarms and other projects. As far as the current state of the art is concerned, in the field of fingerprint locks, optical acquisition is slightly better than semiconductor acquisition. Lie 2, the virtual password is more secure? "The fingerprint lock of our brand has a virtual password function. When using it, add garbled characters before and after the correct password. As long as there is a continuous correct password, you can open the door, which can prevent others from peeking at the password, which is safer than the fingerprint lock without the virtual password. "When it comes to the function of the virtual password, the sales staff will often introduce the various things to the customer with great interest." So, is the virtual password function really effective to prevent others from peeping? Truth: The virtual password function is as long as there are consecutive passwords that are correct, just like the correct code: 1234. The owner presses the hypocrisy code: 25 1234 6, so that the door can be opened. When someone really wants to peek, it is definitely not the three seven twenty-one, remember the whole set of passwords, so you can open the door. Therefore, the virtual password is just a fool, it has no effect at all, it will only increase the difficulty of the user. However, in the fierce market competition, the distinctiveness of products is often the magic weapon for brand success. In order to have a marketing gimmick, many brands often only “make different†in order to be different, and they do not consider these “gimmicksâ€. The practicality, the virtual password mentioned in the appeal is one of the typical examples of superfluous. Lie three, fingerprint lock has no key? Some sales personnel often introduce fingerprint locks to consumers when they emphasize that their products only use fingerprints to open the door. They do not need keys, and fingerprint locks with keys are inferior products. So, is there really no key to the fingerprint lock? Truth: Fingerprint locks are the crystallization of technology in many fields such as mechanical functions, electronic technology, and bioengineering. The operation of mechanical functions and electronic technology has certain limits. The phenomenon of strikes is inevitable. For example, the battery is dead, fingerprints. And the password will be invalid. Especially in the event of a fire or gas leak, the opening of the key with an outsider will be the key to rescue the trapped person. The first gyr fingerprint lock expert introduced: "The relevant national laws clearly stipulate that the smart fingerprint lock must be equipped with a key opening function at the factory to prevent the malfunction of the fingerprint lock in an emergency. Therefore, the fingerprint lock without the key is not in line with the current national conditions. †Lie four, the more expensive the price, the better? Fingerprint locks have always become the "premium accessories" in the home building materials market with noble quality. People always think that the price is definitely more expensive. Sales people often use the customer's awareness to constantly recommend various high-priced fingerprint locks to customers. And the fingerprint lock is really the more expensive the better? Truth: As a high-tech smart product, fingerprint lock needs to use more expensive materials and requires a variety of high-tech skills as a support. Its material cost and technology cost determine that fingerprint lock is not a low-priced product, but this does not mean that fingerprint lock The more expensive the price, the better the quality will be. The research and development expert of the Jierji fingerprint lock revealed: "The price of ordinary fingerprint lock products is reasonable at around 2000-3500. The fingerprint lock material and technology of this price are all at a higher level in the industry. If the price is higher than this value, only two One possibility is that the product is made of special materials, such as stainless steel or gold-plated silver; the second is that this product is unique in shape design, and the price is expensive in the shape design. When the user encounters the design or material, When the price advertises a few thousand yuan of fingerprint lock products, you need to think twice.

Obtaining fingerprint images is the most important part of fingerprint lock work. Therefore, fingerprint collection has become the main point of competition among brands, and it is also the selling point of sales personnel. In the store, we can often see the sales staff eloquently explain the advantages of their own collection technology to the customer. The most common one is: "Do not use the fingerprint lock collected by optical, use a fake fingerprint to crack it. The semiconductor is better, the image Clear, you can identify fake fingerprints." So, in the fingerprint lock acquisition, is the optical acquisition technology really as good as the semiconductor acquisition technology as the guides say?
