Chestny ZNAK – Quality Control

Chestny ZNAK is a handy tool that helps you track product quality and identify counterfeit products. It's a free application that allows you to scan labels, QR codes, and Data Matrix codes, and instantly displays the manufacturer's marking type. You can use it to verify the originality of your purchases and access information about the manufacturer, production, expiration date, logistics, and more.

Using Chestny ZNAK, you can determine whether a purchase is a genuine, non-counterfeit product, and report any violations detected during verification. Complaints about unscrupulous manufacturers are forwarded to relevant control and supervision services. The scanner validates authenticity of marking codes for various products, including tobacco, shoes, medicine, fur coats, consumer goods, cameras, flashlamps, perfume, and tires.

From 2020, milk products, bicycles, and wheelchairs will also be available for verification. For any feedback or queries about the app, please send an email to [email protected].
