The TÜV SÜD Verify app allows you to check the validity of a product or service, or even a document, using a QR code. This is a very convenient way to check the information, as you don't have to print anything out. You just need to scan the QR code, which is located on the product or document. After that, you will be able to see all the information, which is contained in the QR code. This includes the name of the product, the quality, the specification, the price, etc.

It is very easy to use, so don't hesitate to give it a try.
