With more and more Europeans travelling and living in another EU country, demand for cross-border services is on the increase. A significant effort has been already made by the European Commission and member states to make communication between EU countries easier. Numerous projects and initiatives have proved that it is possible, but there is still a long way ahead. Interoperable solutions have been implemented for cross-border services in many areas: e-Health, e-Justice, e-Procurement, business setup. To unlock the full potential of the European Single Market, generic solutions are needed to enable electronic transactions in new areas. The aim of the event will be to present the progress made so far towards this ambitious goal.
