KLT is the earliest OSAT test for domestic fingerprint IC design companies to develop touch chip tests. At the same time, with the development and progress of fingerprint chips, in terms of screen fingerprint IC (ultra -thin) testing, KLT is the first domestic Strip test and STRIP test and Single automation test. Many years of experience has been accumulated in fingerprint IC testing.
Fingerprint chip is an electronic device that uses fingerprints to set fingerprint technology. It can convert it into numerical information and store and identify by scanning the texture characteristics of the human fingerprint. Fingerprint chips are used in various fields, including only mobile phones, banking and finance, access control systems, identity verification, etc., because of their highly accurate, fast and convenient characteristics, they have been favored by users.
The working principle of fingerprint chips mainly includes four processes: image collection, image enhancement, feature extraction and pattern matching.
The advantage of fingerprint chips is that it is highly accurate and secure. As a biological characteristics, the fingerprints of each person are unique and can hardly appear the same situation, so they have high recognition. In addition, the identification speed of fingerprint chips can be completed in a few seconds to complete the entire recognition process, which is more convenient and convenient than traditional passwords and card -inserting verification methods. At the same time, fingerprint chips also have high anti -counterfeiting and tampering, and are hardly cracking and used.
