With the increase in computer crime, it is increasingly important to guarantee the authenticity of digital documents issued by companies, from invoices, to receipts, to transport documents.

By applying the qualified signature to your digital documents, you ensure that the documents that reach your customers are safe and trustworthy.

Thus, your customers will feel more confident when carrying out digital transactions.

Please note that, as of January 1, 2023, in Portugal, according to Decree-Law 28/2019 and with Order No. 49/2022-XXIII, the affixing of a qualified seal becomes mandatory for a fiscally relevant document (ex: invoice) becomes valid in digital format.

How is the digital signature applied to your documents?

To place the qualified signature, and to ensure that the document does not leave the Unicks secure environment, a Hash is generated.

The Hash is like a fingerprint of the document that goes to an HSM (Hardware Security Module) to place the signature securely.
