Experience the whole process of fingerprint film clock-out from zero

Recently netizens circulated some use of cellophane, cans, with a candle-blackened can rubbing the way to make fingerprint film, and then used to punch a good attendance method. Is it really going to work? In accordance with the method is feasible, find a few friends to do the experiment, the conclusion is: completely no effect, too no science and technology content.

There is no way to solve the problem of getting up early, more late, Baidu Search, Baidu Post bar, Baidu know, Baidu Collection stroll over, there is probably a train of thought. Need to exchange production experience can be added luoxiuying2008 (long press can be copied)

That is the silicone fingerprint film, listen to this name is more professional, and the biggest advantage is the low cost, the heart secretly think this may be successful experiment!

Before the test to understand the characteristics of silica gel, in addition to alkali, hydrofluoric acid, not with any material reaction, heat resistance, chemical characteristics of stability, insoluble in water and any solvents, non-toxic tasteless, chemical properties stable.

After the online screening, finally chose a reliable friend, got the silicone fingerprint film set, the production process is very simple, three steps can be done, printing fingerprints, stirring silica gel, smear after cooling can be torn to punch. The whole process is not rework, according to the instructions or video, overnight, since the attendance is no longer a difficult problem.

BTW with the diversity of the social industry, fingerprint checkin is more and more used, all kinds of training, driving school exams will be used to fingerprint card, fingerprint is widely used identity recognition features, but must be cautious use, thoughtful. Now the universal company Punch is used to use blue or green light of the attendance machine, the fingerprint produced in this way is not a problem, the accuracy of the attendance machine is not very high, even if the fingerprint film production has some errors, but also does not affect the success of attendance, and driving school used by the black glue Punch, punch machine itself will not glow, this attendance According to friends said there is a corresponding black gel set can be made, this I did not personally test.

But in the foreseeable future, with increasing security requirements, iris recognition, body temperature recognition, facial recognition, and even DNA recognition will quickly enter the life, but now the cost is high, until the day of implementation, it is estimated to wait until the popularization of technology and the cost of consumables decline.

At that time, perhaps we can not sleep lazy sleep, but, at that time the development of science and technology, we may not have to clock in the company to work, who said not it!
