M-Business Anywhere provides an inline scribble widget that allows signature capture on the device at the scribble label level. There is no large dialog that pops up, so the signer of the document is clearly signing the agreed-upon document.

For information on implementing signature capture in an HTML page, see Capturing signatures with an in-line scribble widget.

For reference material on the API calls that are involved, see PODSSymbolScanner object.
