Credit Card Authorization Form for SquareSpace

I'd like to use JotForm to obtain credit card authorizations from my volunteers at the Telluride Yoga Festival.  Basically, if they fail to show up for a shift, they would be charged the price of a 3-day pass and we would then be able to run their credit card.  Is this possible?

Sorry at the moment this is not possible. A possible solution would be for users to fill in the form and get billed. At the time of the festival, you can refund all the users that showed up.

I think this would be the best and easiest solution to your question.
