So far, there is no clear evidence of medical data and large-scale user data to see whether the vascular characteristics of witnesses will remain unchanged all the year round. Even if it is really unchanged, the existing collection and verification technology fails to reflect the advanced nature of its iterative update. The structure of infrared lamp illumination and development leads to a large module volume, and the image comparison is not as rich as the face algorithm by relying on the original optical photography method. In practical use, the security and convenience do not really exceed the semiconductor fingerprint identification, and it is far from its industry nominal value.
Over the years, none of the finger vein companies in China, including its sources and applications, have really made a profit, and only a few companies have successfully obtained venture capital. Even if the investment is obtained, the capital scale is very small, and it will be over after burning. They didn't really invest in the actual algorithm development. At the same time, the algorithm patent is subject to a series of patents of Hitachi, which can only scratch the ball. Fortunately, the development of finger vein market is not as good as Hitachi expected, so we did not delve into patent infringement, only. This can be judged simply from the market operation information reflected on the websites of companies and the actual sales of products on retail platforms.
In recent years, the venture capital market has become more and more rational, and the industry has changed from exchanging commercial investment to attracting government subsidies to extend its life, waiting for the next venture capital season.
