The component takes an image, reads the QR code on it and writes its value to a variable.
Add the component to the screen and configure it:
If you specify a link in "Link to image with QR code" field, the component will not wait for the user to enter, but will immediately load the image and try to read the QR code.
After the user sends QR code, you can see it in User States section by opening the variables of that particular user. The text read from the QR code sent by the user will be written to the variable.
