Research of fingerprint module detector system

Fingerprint recognition technology is a technology of biology-authentication widely used and legalized in international today because of its low-price and finer application. Fingerprint just is a small part of the skin, but it contains a great deal of information. The veins of the skin are different in pattern and cross point and break point. Medicine has proven that these characteristics are different for each finger and these characteristics are unique and permanent. Hardware system of fingerprint module detection is designed in the paper. This system applies SST89V564 single-chip microprocessor as its core-module and collects fingerprint by ZFM-20 fingerprint module, and then, memories fingerprint data by extended memory and displays fingerprint image by G3245H LCD. The system possesses many merits such as small-bulk and finer ratio of performance-price and rapid transmission and vivid image, and so on. It takes on practical engineering significance.
