Hi, I'm trying to utilize QR code technology (to be placed in email) for each survey. It will also be useful as a marketing campaign where users can just scan and participate in the survey.
I looked around and there seems to be a 2d barcode implementation under admin/classes/tcpdf/
Here's my question, is there a 2d barcode functionality in LimeSurvey? To convert the URL of a survey into QR code and make it available in the email?
A link is more convenient than qr code in an email. But if you need to send qr code image
to others, just can generate qr code
with other tool and copy the qr code image to email.
