You can generate a QR code to go directly to an Opportunity Survey. After the QR code is generated, you can download the image to insert it into an email or even print it to post it for your volunteers to scan it with their device to directly take a survey. This is very useful if your opportunity happens to have multiple surveys attached and you would like to target just one.
Open the Opportunity that you would like to get the QR code for.
Click on the Surveys tab
Click on the Survey
Click on Generate QR Code
You can now either download or Print the QR When your volunteer follows the QR code, they will see a login screen and then the survey after a successful login.
