Abstract: A system and method for collecting a signature using a smart device are disclosed. A signature module executing on a smart device may allow a user to input a signature via the smart device display with a pixel size larger than then pixel size of the smart device by causing a viewable portion of a signature file to scroll relative to the display while the user is inputting the signature. In addition, the signature module may display to the user with an interactive pen tool, that functions as a “virtual pen” to allow a user greater control over inputting his or her signature into the smart device. After a signature has been captured, a document viewer module executing on the smart device may allow a user to appropriately position and size the signature for placement in a document being viewed on a smart device.
