Ways to collect a physical signature with a web site on iOS

Question

I'm looking to fill out a form from a web page that will include a box to collect a physical signature, on an iPad or iPhone. Think of a repair visit acknowledgment form, where after the technician does some work they can fill out things on the form on the website, and then hand the iPad to the customer to sign (using a stylus) What kind of technologies are an option there?

A flash control isn't an option because it doesn't run on iOS. Same with a Java applet.

A native iOS app is not an option because the distribution profile (around 350 users) doesn't fit (and anyway, relying on Apple's permission isn't desirable here).

Answer 1

If you are going to roll your own, I'd use JavaScript which can detect touches on the iPhone, but I don't know whether it is accurate enough for your use case. There a Javascript library called jQTouch and it has touch events http://code.google.com/p/jqtouch/wiki/CallbackEvents.

Answer 2

Super Signature seems to do exactly what I need. Thanks @Pekka!
