On the axis of digital transformation

The use of Electronic Signatures, both remotely and in person, as the replacement of the handwritten signature on paper is in the center of the digital transformation of companies in their relationships with customers, suppliers and employees.

These signature processes must comply with all legal requirements to be equal to handwritten signatures. They must identify the signatories, visually present the documents to be signed at the time of signing, certify the document and its acceptance with a qualified time stamp that makes both the document and the moment of its acceptance inviolable and, last, demonstrates the intentionality of the signatories.

The Electronic Signature not only reduces the cost and time of handwritten signature processes using paper, but adapts to the preferences of new digital customers for high mobility.

Main applications of the electronic signature


The processes related to contracting have been greatly facilitated with electronic signatures. A new contract signing, renewal, cancellation or modification of contract conditions can be done in minutes, proving the full identification of the signatories, the integrity of the documentation, the intentionality and its non-repudiation.


The entry into force of the new European regulation on data protection (GDPR) requires companies to obtain customer consent prior to the use of their personal data. The electronic signature is the simplest option for signing the express consent within an electronic contracting process.


The electronic signature process with the additional signature of the SEPA mandate provides the highest legal and normative level for obtaining direct orders or mandates according to European Regulation 260/2012, reducing the risk of default.
