A system that allows a document to be sent to an authorized signer at a remote location for signature. The signer can manipulate a signature block or other indicator to anywhere on any page of the document on a handheld device like a smartphone. The signer can then authorize signature. A server or other central system can then fetch a digital replica of the signer's actual written signature and affix it to the document at the specified location. A new signer can enter a signature into the system remotely by photographing it with the handheld device and sending an encrypted version of it to the central location or server.
