Iris Recognition Device, Manufacturing Method Therefor and Application Thereof

A constructing method of facial characteristics, comprising the steps of:

• (A) capturing facial characteristics of a user by a face recognition module and generating an image data flow and transmit said image data flow to a background processing component;
• (B) capturing iris characteristics of said user by an iris recognition module and generating an image data flow and transmitting said image data flow to said background processing component;
• and
• (C) converting said image data flow to generate identity information of said user said background processing component, and transmitting said identity information of said user to an operating component for encoding process so as to construct facial characteristics of said user.
