Intelligent Scan (biometric authentication) combines iris scan and face recognition to allow convenient unlocking and in some cases provides enhanced security for certain authentication services.

 

  • What are the benefits of Intelligent Scan? 
  • How to setup Intelligent Scan?
  • What are the common scenarios of using Intelligent Scan and what to do about it?

 

Benefits:

 

  • Unlock the screen without problems even when the surroundings are dark or too bright
  • Low light environment: iris scan will be activated if face cannot be recognised
  • High light environment: face scan will be activated if iris cannot be recognized

 

Please note: For payment or financial services, iris scan will be activated first, followed by face scan to prevent spoofing.
