About this app

Your main assistant for product quality tracking and counterfeit detection.
Chestny ZNAK is a free application, which allows you to scan labels, QR codes and Data Matrix codes. Simply scan the digital code on the product label, the application then verifies the manufacturer’s marking type and instantly displays the result.

You can verify the originality of your purchases, protect yourself from counterfeits and find out all the information about
– the manufacturer
– the date, time and place of production
– expiration date
– the logistics of goods from the factory to the store and much more.

If your purchase has been marked, you will find out if it is a genuine, non-counterfeit product.
If the application detects a violation during verification, you can report it. Depending on the type of violation, a complaint will be forwarded to the relevant control and supervision services. They will analyze appeals and review unscrupulous manufacturers.

The scanner determines authenticity of the marking codes for tobacco and shoe products, medicine, fur coats and natural fur products, consumer goods, cameras and flashlamps, perfume and tires. Milk products, bicycles and wheelchairs will also become available for verification in 2020.

All suggestions and questions about the app you can send to support@crpt.ru.
