Overview
HCFP-050 fingerprint readers refers to the technology introduced, with high speed DSP processor as the core, combined with optical fingerprint sensor with company independent intellectual property rights, a fingerprint input, image processing, fingerprints, search and store templates, and other functions of intelligent fingerprint readers.
 
Product principle is introduced
Fingerprint readers HCFP-050 operation process is as follows:

operation Registered fingerprints
Standard process Open the equipment to obtain characteristics of fingerprint image - > generate 1, access to fingerprint image - > generate features 2 - synthetic fingerprint template - stored 1 to fingerprint database
To streamline the process Open the device to obtain characteristics of fingerprint image - > generate 1, storage characteristics 1 to fingerprint database
 

 

operation Search for fingerprints
Standard process Open the device to obtain characteristics of fingerprint image - > generate 1 - search fingerprint - returns the position and score
 

 

operation Compare the fingerprint
Standard process Open the equipment - gain characteristics of fingerprint image - > generate 1 - loaded fingerprint characteristics to compare features 1 and 2, 2 return to the position and score
