As we all know, human fingerprints are extremely complex, detailed, basically unique and lasting patterns. All those properties that they process, make the human fingerprints one of the perfect and most reliable methods of human identification. The fingerprint recognition tech achieved both low price and high efficiency for security, without a doubt, such technology earned its wide spread and utilizations. We can see them on our phones, various facilities or institutions, fingerprint door lock for home is now even a trend, for we are always tend to pursue the smarter and easier life style.

As an identification technology, fingerprints capturing and reading are the two mainly parts. So, besides the security level, how accurate the fingerprint readers could capture and detect the fingerprint pattern is the most crucial and direct criteria for evaluating such device. Therefore, those most concerned problems are came from here. In our daily lives. There would be a considerable amount of factors that can compromise the functionality of the fingerprint recognition devices. We all know that our fingers would be attached with many different objects, such as our own skin secretion, oil, small particles, dust, or any form of distortion of our fingertip, and so on.

I bet most iphone users had encountered this problem, it took forever for the fingerprint reader to detect and match up your fingerprint with the data base. And it’s fairly annoying. When you want to deploy fingerprint door lock for home, these problems got even more severe, you cook, clean, eat at home, and sometime, you go home carrying or holding something heavy or dirty. So, the fingerprint door lock for home would face the challenges more. Now, we can draw a conclusion here, security and reading capability would be our standards to examine a product.

To solve these deal-breaker level problems. The semiconductor fingerprint reader now is slowly replacing the optical fingerprint reader (the optical fingerprint reader takes a visual image of the fingerprint through a digital camera.) and the reason why they are being replaced is that they can only deliver very poor performance while dealing with the dirty fingers, dry fingers etc. also, they can’t tell whether the fingerprint is real or not, since they just compare the optical images and nothing else. Hence, the semiconductor fingerprint reader is to save the day. They use thousands of Capacitors to offer the faster, more accurate and meticulous scanning. Moreover, the semiconductor reader only recognize living object, so, someone with the duplicated fingerprint of yours would not be able to open the door of your home.

Yet, naturally, even the semiconductor reader has problems. Normally, they are hard to maintenance, easily scratched and affected by Static electricity, they are more sensitive hence more vulnerable. As a customer, you probably already run through some door lock suppliers to gain the information, but here let me introduce Kolman, and how we solve this new problems for good, hope that we can also offer you some useful information for your journey of choosing.
