As different as the social security systems are within the EU member states, the corresponding administrative structures, the digital technologies used by them and the administrative procedures embodied in these technologies all differ as well. It will take a long time to make them all compatible throughout the EU and to enable data and information to be exchanged. EESSI has clearly shown this to be true. An EU-ID, which is a main condition for implementing the ESSP project, will also require further adjustments to be made in the member states and it cannot be implemented in the short term.
Full digitisation in the social security sector and coordinating the systems in cross-border situations as well as implementing the objectives to be pursued through digitisation are both necessary and desirable. Simplifications such as paperless communications will be welcomed. Interlinking the specific projects is precisely where efficiency will be gained and the potential for all actors involved will become apparent. However, as desirable as implementing the projects is, a structured approach is needed so that those involved in the implementation, i.e., the social insurance institutions, can keep up.
