QR code reading

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:

  1. Specify the name of the variable which will be used for saving input data.
  2. Specify on which screen it will be redirected in case of an error. For example, if there is no QR code in the image, it could not be read or the user sent a text or video instead of the image.
  3. Specify in which screen it will be redirected if the QR code is successfully read. If you do not specify it, the next components will be executed on the screen.

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.
