Inserting signature field that works in iPad

just curious?

Hi, 

We already have a widget for that. It works fine in iPad.

The E-Signature Widget allows your form users to draw their signatures using their mouse, touch screen device, or any other input device that will allow them to draw their signature on your form as a confirmation or verification of consent.

Here's a guide on How to Insert Widget on your Form - (http://www.jotform.com/help/252-How-to-Add-a-Widget-to-your-Form)

Hope this helps. Thank you.
