As of today, Croatia is connected to the Schengen Information System (SIS), the most widely used information sharing system for security and border management in Europe. Croatia will now be able to exchange information with other Member States through SIS on persons wanted in relation to terrorism and other serious crimes, missing persons and certain objects such as stolen vehicles, firearms and identity documents. This will further enhance information exchange between Member States and will contribute to the security of all European citizens. Croatia's integration into SIS will also help reduce waiting time at land borders between Croatia and Slovenia - with both Member States having access to SIS, there will no longer be a need for checks against databases on both sides of the border. The Commission had proposed the gradual integration of Croatia into the SIS on 18 January 2017, with the Council adopting the Commission proposal on 25 April 2017 and setting the date for the entry into operation for 27 June 2017. In December 2016, the Commission presented a legislative proposal to further strengthen the operational effectiveness of the Schengen Information System by improving the security and accessibility of the system and including new alert categories as well as the obligation for Member States to create SIS alerts in cases related to terrorist offences.
