Is there any free survey web application which provides printed single access codes?

I have seen that Sogo Survey supports this, but this requires a paid upgrade.

So I am looking for a free alternative.

P.S. I posted this question on webapps.sx some time ago, but it was considered as off topic and deleted. I hope it is on topic here. If not, please make a suggestion where to ask.

Scenario:

• In the webapp, survey owner generates 50 unique codes, and is given a convenient way to print them on sheets of paper
• Survey owner distributes the unique codes to 50 persons, for instance at a conference
• Each of the 50 persons goes to the website, logs in using their code, and completes the survey
