Hello, Thant Zin.

Place the barcode into a hidden question.
This will hide it from the interviewer.
Why do you need to hide it from the supervisor??

Best, Sergiy

Dear Sergiy

Thank you very much for your reply.
We need to hide preloaded barcodes because we are measuring which each barcodes (preloaded barcode and new) are match or not . we wouldn’t show this QR codes to interviewers and supervisor. But we can’t yet to find it. Please suggest .

I don’t understand the explanation.

What is the negative impact of the supervisor seeing the value of the preloaded barcode on the quality of data being collected?
