EU4Digital will assist Eastern partner countries to pilot interoperable cross-border electronic identification and authentication based on common principles and formats. These pilots will test the ability of eID-holders to access electronic services in another country. They will also allow Eastern partner countries to assess the readiness of their national infrastructure for eID, providing the opportunity to enhance interoperability and accessibility, as well as to identify potential breakthrough areas for eID and electronic service adoption and take up. The pilot activities will also promote multi-lateral relations and encourage partner countries to conform with agreed-upon standards and key principles.
