Overview
- MiDNI, which took effect Thursday, must be accepted by public and private entities as an ID equal to the plastic card.
- The Junta Electoral Central barred the app for voter ID following a Partido Popular request, so it will not be valid at the May 17 Andalusia election.
- The app generates a short‑lived QR code that verifiers scan with MiDNI or the midni.gob.es checker, and it pulls identity data in real time without storing it on the phone.
- Activation requires a current physical DNI, registration online with a card reader or at police stations or municipal PADs, then app setup with DNI numbers, a password, and an SMS code.
- Use needs an internet connection and compatible QR readers, so officials advise carrying the physical card during the phased rollout, and the digital ID cannot be used to cross borders.
