About this app

※ What is JayJun?

JayJun reads tags containing unique data and tells the users whether the product is counterfeit.

Using the technology to authenticate products by comparing unique serial number assigned to each product with data cryptographically embedded into a QR code, JayJun with its robust security cannot be replaced by other anti-counterfeiting technology.

※ Features of JayJun

1. Easy Authentication : Users can easily authenticate products with high recognition accuracy.

2. Fortified Security : The technology used to compare the physical number with the hidden encrypted pattern in the QR code is a proprietary technology developed by JayJun.

3. Fast Authentication : Users can authenticate products in just few seconds.

4. Customer Reports : Users can report the results of authentication and help identify the source of counterfeit products.
