Currently, the system only generates QR codes for the live survey link. It is one QR code for all the respondents and also it is anonymous.
However, you may use the export batch feature. That will give you a unique tracking link
for each respondent. Once the tracking links are generated. You may use the external website to convert that link into a QR code.

Please note these are external websites. Hence, test it with dummy data and then use it for actual respondents. As it is a 3rd party application we will not be able to provide support for the QR codes generated using 3rd party websites."
