is it possible to handle QR codes for questionnaire control? Specifically, if the questionnaire is printed on paper.
Yes, you can have a question type barcode in Survey Solutions.
Thank you, but the idea is to use QR codes to identify a printed questionaire, this would be very useful to keep a good control of the survey
Yes. As i said, you can add a barcode question which can be used to read the barcode printed on the questionnaire booklet and store that id with the capi interview.
I don’t know that you can use it in this way, thank you
