Recently, a colleague needed me to append my signature to a document he had emailed to me. It would have been too cumbersome to print out the document, sign it and then scan it back to him so we started looking for options that allow drawing one’s signature, saving it as an image and then inserting it on the electronic document. These applications are particularly useful and can be used on projects where stakeholders are geographically dispersed and they need to endorse a document.
