Digital and electronic signature are not the same.

The main difference between the Smart Sign and the digital signature lies in its probative value.

In the case of the digital signature , there is a iuris tantum presumption in its favour, which implies that a digitally signed document is automatically verified as correct, it is presumed -unless there is proof to the contrary- that it comes from the subscriber of the certificate associated and was not modified.

On the contrary, in the case of the Electronic signature, the burden of proof is inverted with respect to the previous one: if it is unknown, the signature corresponds to the person who invokes it to prove its validity.
On the other hand, both signatures ensure the integrity of the document, that is, that it was not modified after the signature.

A Digital Certificate is a computer file generated by a certification services entity that associates identity data to a natural person, organization or company, thus confirming their digital identity on the Internet. It is valid to authenticate a user or a website on the Internet, so the collaboration of a third party that is trusted by any of the parties involved in the communication is necessary

Any digital document can be signed, such as salary receipts, contracts, invoices, etc. that are in PDF format.

The Digital Signature enjoys a legal presumption "iuris tantum"; this means that if a digitally signed document is verified correctly, it is presumed, unless proven otherwise, that it comes from the subscriber of the associated digital certificate and that it was not modified.< BR>
On the other hand, to recognize that a document has been digitally signed, it is required that the digital certificate of the signer has been issued by a Licensed Certifier.
