The semiconductor fingerprint module IDWD1020B is a touch fingerprint identification module, consisting of an ID809 fingerprint identification algorithm board and a capacitive fingerprint sensor. Run a new generation of high-performance IDFinger fingerprint recognition algorithm, with high security and good experience. The IDWD1020B processor is an Edward ID809/811 with powerful performance and low power consumption. The collection, storage and comparison of fingerprints are all processed inside the chip. The processing speed is fast and the development interface is simple. It is convenient for the secondary development of industry users, effectively reducing the difficulty of product development and shortening the product development cycle.
