Documento Nacional de Identidad electrónico (DNIe) is a Spanish eID. It is in line with the EU directive on electronic ID, and it is a smart identity card with a chip containing certificates for authentication and digital signature, similar to Estonian ID-kaart, Belgian .beid, and many others. The cards are issued to Spanish citizens. In order to use it electronically, the subject must physically go to a passport-issuing police station where they can activate the chip on the card using a self-service kiosk, called “Punto de actualización del DNIe”.
The end-user portal for information about DNIe is https://www.dnielectronico.es/PortalDNIe/. The site contains information regarding what DNIe is, how to use it, and where you can use it. There is no central support organization where you can ask for help with DNIe. When assisting end-users with their DNIe problems, refer to the website above, which provides software downloads and also a client executable which can be downloaded and used to verify the certificates of a DNIe card.
