With Gasco Biometrics, the information provided is reliable and its verification in two steps is done in such a way that the verification is guaranteed. In addition, all this in compliance with the RGPD, since the information that the citizen carries is sovereign and nobody else has it. Our solution starts with different ways of obtaining personal information, which we integrate during the secure registration process and the issuance of the identification code. Only the code remains in a single copy owned by each person.
