biometric fingerprint time clock are divided into two categories: the first kind is simple print class, punch, the original records data through the roll machine directly printed on the card, the card record time as the original attendance information, the first users need not do any prior training then immediately use; The second type is storage class, punch, the original records stored in the data directly in attendance machine, and then through the computer collection summary, again through the software process, and finally needed for the formation of check on work attendance information or queries or print, the attendance information flexible rich, the first user need to do some prior training to gradually master all of its use a function.

The first generation is plug-in fingerprint time clock, in the 70 s, gradually took the place of manual record attendance, he is in a metal card regular a hole, and then use sensitive element and light projection difference between people's Numbers, 8086 processor or 80286 processor. But metal easy deformation, caused the identification error. Plus resolution limit, this kind of roll machine in frequently thousands of people in the coal mine without widespread promotion.The second generation is bar code roll machine, in the beam of the miner's lamp using optical principle projection roll machine a barcode image, workers well under the miner's lamp irradiation the special attendance probe can check on work attendance. This way, convenient and quick, our country the first down well with this is the kind of roll machine. But the miner's lamp after all is a kind of often working in the bad environment of the instrument, so the maintenance is frequent, projected out of shape is a bundle of disturbing everybody's a problem..


Inward and outward biometric time clock safety management system is a new type of modern safety management system, it integrates microcomputer automatic identification technology and modern safety management measures for an organic whole, it involved in electronic, mechanical, optical, computer technology, communication technology, biotechnology, and many other new technology. It is an important department solve gateway to realize safety management of effective measures. It is applicable for various confidential departments, such as Banks, hotel, room, armory, confidential room, offices, intelligent village, factories and so on.



Refuse truthful straightforwardness and biometric time clockh] are two i nteracting pointer, reduce the one of them, and the other one will rise. Because acknowledge false rate is a very key pointer, we must make the pledge that at least one months won't appear too much miscarriage of justice. To appear miscarriage of justice, must administrator in the management program modification record, in order to ensure the correctness of check on work attendance. Input number and combined with card use is to solve the performance of system identification is the most effective method. Than when fingerprint only with their own fingerprint for comparison, so that there is no to recognize the possibility of false, in order to prevent generations attendance, identify false rate can be adjusted to 0.1% or so, the refuse truthful straightforwardness is 0.6%, the identification of difficulties to reduce 24 people.

time attendance clock to person's fingers end positive skin rough and uneven produce grain line. Grain line regular arrangement form different grain type. The starting point of the lines, the destination, the combining site and the branch point, called the details of the fingerprint feature point. Fingerprint recognition means that by comparing different details of the fingerprint feature point for identification. Because each person's fingerprints are different, the same person is between fingers, fingerprint also have obvious difference, so the fingerprint can be used for identification of identity. Fingerprint identification technology is the most mature and the price cheap biometric identification technology. At present, fingerprint identification technology are widely used, we not only in the entrance guard, attendance system can see the figure of fingerprint identification technology, on the market have more fingerprint recognition application: such as notebook computers, mobile phones, automotive, bank payments can apply fingerprint identification technology.

time and attendance systems is the centre of the entrance guard system, like as the human brain. The entrance guard controller performance directly affects the stability of the entrance guard system, and system stability directly affect the customer's life and property safety. At present the Chinese market access controller products is numerous, function little difference, but quality is uneven. Therefore for engineering business, product selection is particularly important. So how to choose high quality door controller? We through many years of practice experience and summed up the following share: Our principle is "stable and reliable performance, function and practical, price advantage, the sustainability of localization service ability".

A, prevent crash design The time and attendance systems halted like car engine flameout as. No matter the function of the controller design again strong, if a crash, the controller can't work at work, any function can reflect. If in the application of crash appeared, means the controller control area can't normal access, and may even cause serious security hidden danger and immeasurable loss.Second, the capacity of the relay The entrance guard controller output is by relay control. Controller work, relay to frequent movable, and every time when opening, there is a transient current through the. If relay capacity is too small, instantaneous current may exceed the capacity of the relay, and soon, damage to the relay. Generally relay capacity should be greater than electric lock peak current more than 3 times.The entrance guard system used to protect personnel and property safety, so the system itself must be safe. What say here high security, on the one hand, is refers to the products or system of the natural attribute of or quasi natural attribute, should ensure that equipment, system operation of the safety and the safety of operators, such as: equipment and the system itself to resistance to high temperature, low temperature, hot and humid, and can prevent electrostatic, anti-interference, etc.; On the other hand, entrance guard and security system should have the function of preventing the man-made destruction, such as: has tamper alarm, etc.

The meaning of time and attendance systems is very wide, generally can be divided into physical characteristics and behavior features two kinds. The body features include: fingerprints, vein, palm type, retina, iris, body odour, face, and even blood vessels, DNA, bones, etc.; Behavior characteristics, including: the signature, speech, walking gait, etc. Biological identification system, on the biological characteristics of sampling, extraction its unique characteristics into digital code, and further the these code composition feature template, when people with recognition system interaction for identity authentication, recognition system through the gain its characteristics and features in the database template matching, to determine whether the matching, thus decided to accept or reject person.

employee time clock systems suppliers
The ministry of education carried out winter "biometric time clock" long distance running events, nov. 12, in 12 provinces and cities more than universities in fulll swing. The ministry of public security said yesterday, other departments could acquisition citizens fingerprints, did not check legal basis. The ministry of public security answer, according to the regulation, the public security organ in investigation activities can collect, manage citizens fingerprint, and has a set of strict management system. "For other departments could acquisition citizens fingerprint, we did not check relevant regulation". It is reported, November 9, 2007, promulgated "the public security organ fingerprint information work regulations clear, fingerprint information work task is," for criminal investigation and cracking down crimes, and to provide evidence for the social security management to provide information support ". "There is some important unit using fingerprint technology certification staff identity", to run fingerprint, the ministry of public security said: "the school should be subject to strict system to standardize the management, students can also put forward to the school security requirements, and at the end of the activity to destruction."



biometric time clock systems suppliers, many in the automatic identification system entrust others development packaged into their own products, or research and development team are insufficient or the boss itself not to participate in the technology development, research and development personnel flow caused by the system maintenance risk. Cause users have system upgrade demand and DEBUG must wait or have a problem not be able to process, and even fingerprint time clock installation adjustment timely the seller will take to many times repeatedly the test delay customer inspection and user use, this also is current users often encounter problems.

By fingerprint time clock described cheating, for the majority of students can't accept, are strongly attack. "Through the fingerprint puncher, my information will not be disclosed?" Shenzhen university he said, schools require long distance running is no problem, the school how to ensure that students information will not be disclosed? So many students fingerprint material be in a company to hand, and how do they make confidential work? Once the material information leakage, who will be responsible for? According to media reports, college students winter long distance movement at the beginning of the brewing, it is noted that can advocate not compulsory, but education department "prevail over all dissenting views", impose, even use "fingerprint puncher" equipment.

In the "biometric time clock" "time and attendance systems", the experts identified as "the university management sunshine long distance running activities effective means" began to failure, wuhan many students to cope with sign in many, some cut trot, some riding a bicycle round, what's more riding on electric car taking part in a long distance. Out of fingerprint sets of the same considerations, nanjing some colleges and universities to prevent students "cheating" installed cameras. So quickly out of the "system patch", really let "fingerprint puncher" lose face.


fingerprint time clock machine adopts the Intel company high-performance flash memory, but a store 50000 records information, is the 21st century big small and medium-sized enterprise employees' attendance to one of the best evaluation way, in addition to the function outside, it is suitable for various only need accurate identification on various occasions.
