jSignature is a jQuery plugin that simplifies creation of a signature capture field in a browser window, allowing a user to draw a signature using mouse, pen, or finger.
Features:
- Works in all mainstream browsers that support Canvas or Flash
 - Captures signatures as smooth vector images. (Yes, SVG is supported!)
 - Ingenious, super-efficient (i.e. not lagging) real-time curve smoothing.
 - Allows manipulation of signature strokes, like “Undo last stroke”
 - Automatically adapts to your page’s layout and colors.
 - Free and Open Source.
