What is the electronic DNI?

The electronic DNI (ID card no.), in addition to the information found in a traditional DNI, incorporates a tiny chip capable of securely storing information and processing it internally. This chip contains, on one hand, the same information that appears printed on the DNI (personal data, photo, image of the written signature and fingerprint) and, on the other, the Authentication and Electronic Signature certificates. The DNI-e is a document that certifies the identity of each citizen, as well as allowing for the signature of all types of electronic documents.
