The prime ministers of Estonia and Finland, Andrus Ansip and Jyrki Katainen, will meet later this month to discuss Finland's plans to adopt the X-Road system, the "backbone" data exchange layer that connects the different databases used by Estonia's various e-services.
It was reported in September that Finnish officials were planning to start using the X-Road system, which was introduced in Estonia in 2001 and uses an open source software.
Estonian officials hope that getting Finland on board will open a window for promoting e-services elsewhere in the EU.
The Estonian prime minister has been urging European leaders to transition major government activities to electronic systems. Ansip has said the reforms would improve data sharing and save millions of euros by cutting down on paperwork.
