Signatures used for very important purposes are only decoration. They must be used in conjunction with something else (a notary, an independent exchange that confirms that the signature is actually binding, etc.). The electronic signature is completely different: there is no visible artefact anymore, but a process that seals a document and (under appropriate legislation), certifies that the signer is who he is. A visual object is sometimes added for aesthetic purposes.
