What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Our online JotForm form builder does not process payments, we are using APIs to integrate 3rd party payment processors which I believe are PCI compliant. You can learn more about these payment integrations on this link: http://www.jotform.com/help/323-Mastering-Payment-Form-Integrations-with-JotForm
There is also another thread that has that same question on this link: http://www.jotform.com/answers/336940. You can also check the answers of my colleagues there.
I hope that helps.
Update: JotForm is now PCI DSS compliant. We have PCI Service Provider Level 2 certificate. We'd happy to provide certificate to any users who would need it for their payment gateway. Just contact our support team.
