Advanced Electronic signature vs Ink Signature on Paper
In the event of a dispute, an ink-on-paper signature (known as a handwritten signature or holographic signature) may require the completion of an expert handwriting test that compares the disputed signature against several indisputable signatures. The advanced electronic signature is based on article 26 of the EU regulation 910/2014 (EIDAS) that links the signatory with what is signed in a context of electronic evidence.
In the event of a dispute, the electronic evidence must demonstrate the link between the signer and the signer and the identity of the signer.
