## What is Zn?

This app is to enable Zn customers to identify authentic and counterfeit Zn products .  It has been designed for simplicity in mind so that Zn customers can easily use the app to perform the product authentication process to identify authentic and counterfeit Zn products.

After installing the Zn App,  users can use the app to scan a QR Code with anti-counterfeit feature printed on the Zn products to perform the product authentication operation.

During the scanning, the user will be guided in the product authentication process with detail instructions such as 
1) Holding Instruction: Too Far, Too Close, Tilted.
2) QR Code Detection Instruction: Using Green Color to indicate the QR Code is in focus.
3) Product Authentication Results: Genuine Product or Fake Product.

With this app, we can help Zn customers identify genuine Zn products and allow them enjoy the superior quality of Zn products.
