Overview of fingerprint module

Release time:2024-08-01 17:20:55

A fingerprint module is a hardware device that uses fingerprint recognition technology to identify and verify human fingerprint information. It mainly consists of a fingerprint sensor, a fingerprint image processor, and a fingerprint comparison algorithm. Fingerprint sensors are responsible for collecting human fingerprint information, usually using optical and capacitive methods. The fingerprint image processor processes the collected fingerprint images, extracts fingerprint features for storage, and uses them for fingerprint comparison. The fingerprint comparison algorithm is used to compare and match the collected fingerprint data with the stored fingerprint information to determine whether they are the same person.

The fingerprint module has the advantages of high security, convenient use, and fast recognition speed, and has been widely used in fields such as mobile phones, tablets, smart locks, and access control systems, becoming one of the mainstream technologies for biometric recognition. Meanwhile, with the continuous development of fingerprint recognition technology, fingerprint modules have also evolved, gradually achieving higher recognition accuracy, faster recognition speed, and larger capacity.
