Fingerprint recognition attendance machines have entered the market for seven or eight years, forming a certain scale, many test models, retail prices ranging from 200-15000 yuan. The main advantage is that there is no need to carry a card, which effectively eliminates the generation of punch cards and has no card loss. The disadvantage is that when the fingerprint attendance machine is used by more than a few hundred people, the processing time is slower than other methods of punching. If it is disturbed by static electricity, sweat, salt, other artifacts, fingers worn, close to the angle or pressure is not appropriate, the acquisition head is difficult to read fingerprints, light identification efficiency is low, and identification of the serious ones fails.
Fingerprint attendance features
Fingerprint attendance has the characteristics of fast, accurate, and convenient recognition, allowing attendance to be intelligent. However, due to the limited life of the fingerprint film in use, high-end fingerprint attendance machines have made breakthroughs in this regard.
Fingerprint identification system is to collect, analyze and compare living fingerprints through special photoelectric conversion equipment and computer image processing technology, which can quickly and accurately identify individual identities. The system generally includes processes such as fingerprint image acquisition, fingerprint image processing, feature extraction, feature value comparison and matching. Modern electronic integrated manufacturing technology enables the miniaturization of fingerprint image reading and processing equipment, and the rapid development of personal computers provides the possibility of performing fingerprint comparison operations on a microcomputer or even a single-chip microcomputer. Excellent fingerprint processing and comparison algorithms ensure the recognition. The accuracy of the results.
Therefore, the fingerprint attendance machine can close the work attendance when the finger skin is in the correct angle direction and is close to the user's fingertips.
The key part of a fingerprint attendance machine, also known as the most vulnerable part, is a fingerprint film. The longer the fingerprint film time, the lower the fingerprint recognition rate. In the absence of any human scratch damage, a fingerprint film is generally more than one year later, more and more fingerprints are not recognized or need to be repeatedly identified. Is to replace the fingerprint film, replace a fingerprint film needs several hundred dollars, not included in the service charge, is a separate collection of material costs, usually about one year will be replaced.
Fingerprint attendance machine main functions
Fingerprint attendance machine is the use of fingerprint recognition technology to solve the problem of enterprise attendance management. The main functions of the fingerprint attendance machine are as follows:
The fingerprint of the attendance personnel is collected through the fingerprint collector in the machine, due to the uniqueness of each fingerprint. There is no special accident. Everyone can have 2-3 fingers and the collection work is convenient.
After the fingerprint attendance machine senses the fingerprint, it is convenient to compare it with the fingerprints it has collected and stored, and it can be completely safe. After confirming the identity of the personnel, record the time and date, and form a report through software processing attendance data. The data is reliable.
In the absence of cheating in the use of fingerprints, fingerprint attendance can basically guarantee the phenomenon of generations punching cards, and there is no need for cards and other consumables, as long as the purchase of machines connected to the computer can be used.
This last step is optional (because the recorded results can be found in the attendance machine). If necessary, the report that has already processed the data can be printed by the printer.

Fiberglass cloth has become a widely used material in various industries due to its exceptional strength, versatility, and heat resistance. This cloth is made from woven strands of fiberglass, resulting in a lightweight yet durable fabric. With its high tensile strength and resistance to chemicals, abrasion, and extreme temperatures, fiberglass cloth finds applications in a wide range of fields. It is commonly used in the manufacturing of composite materials, insulation, and protective coverings. The flexibility and moldability of fiberglass cloth make it an ideal choice for reinforcing structures, creating custom shapes, and providing insulation. Whether in construction, automotive, aerospace, or marine industries, fiberglass cloth offers a reliable and efficient solution for numerous applications.
