The graphometric signature is that electronic signature in which the signature path is captured using a tablet and added to the electronic document. Depending on the technology used, it can save the biometric data of it. It is therefore a simple electronic signature, and may sometimes reach an advanced electronic signature, and sufficient evidence of its process must be provided to justify the signer's identity and the integrity of the transaction. 

On the other hand, the electronic signature based on electronic certificates issued by a Trust Service Provider, guarantees at all times the integrity of the document and the identity of the signer. When this is done by means of a qualified signature creation device (see a card or token) the qualified electronic signature unlike the graphometric signature, is equated in all legal aspects to the handwritten signature, guaranteeing its full legal value and enforceability of any document against third parties.
