Essentially point your smartphone camera or QR code scanning app to a SAVITAS QR code to scan and click on the displayed link. Generally , the only thing you see is a 'thank you for scanning' message. That is all.
For smartphones that do not have QR scanning capabilities or app, the website also offers the possibility to scan. Using your smartphone web browser, go to savitas.io and you will see a button allowing you to scan a QR code.
