The Croatian eID card, known locally as the eOsobna iskaznica (eOI), is Croatia's official electronic identity document, issued by the Ministry of the Interior. It is a smart card with an embedded chip that can hold two digital certificates, one for online authentication and one for a qualified electronic signature under the EU eIDAS regulation. The card is used to access the e-Citizens (e-Građani) system and other online services.

Verification works through the National Identification and Authentication System (NIAS). The person proves who they are with their eID card and its identification certificate, or with the Mobile.ID app linked to an activated card, and consents to share their identity. Because the eID card is chip based and certificate backed, it provides a high level of assurance without a selfie or document photo step.
On a successful authentication, verified identity data tied to the card is returned to your service, along with the person's OIB, the permanent 11 digit personal identification number assigned by the Croatian tax administration.
The customer proves their identity with the eOI card and its identification certificate, or with the Mobile.ID app linked to an activated card, through the NIAS authentication system.
NIAS confirms the card and certificate are valid and the person consents to share their identity data with your service.
A verified result, identity data such as name, date of birth, and OIB, and a full audit record flow straight into your Zenoo case.
Chain these into one Zenoo Studio flow so a single journey handles identity, screening, and fraud.

The person authenticates with their eOsobna iskaznica card and its identification certificate, or with the Mobile.ID app linked to an activated card, through the NIAS system. Zenoo then returns a verified result with identity data such as name, date of birth, and OIB.
