Credit Card Processing

I currently only have Paypal connected to my JotForm account but my form gives customers the option of using paypal or paying with credit card.  If they opt to pay with Credit Card but I don't have a processor connected to my account, how will they be billed or I receive payment?

Thank you!

I've tried submitting your JotForm and see that the form redirected to PayPal page. When I choose to pay using Debit or credit card, the page redirected to the page showing the following screen. 

If the user is not having PayPal account, he can sign-up for a PayPal account by linking his card information so that it can be processed as a PayPal payment. So, it is not required to have any other processors to receive the payment.

Hope this information helps!
