The Commission shall, not later than 26 June 2012 , submit to the European Parliament and the Council a report based on a large scale and in-depth study carried out by an independent authority and supervised by the Commission, which shall examine the reliability and technical feasibility, including through an evaluation of the accuracy of the systems in operation, of using the fingerprints of children under the age of 12 for identification and verification purposes, including a comparison of the false rejection rates occurring in each Member State and, based on the results of that study, an analysis of the need for common rules regarding the matching process. If necessary, the report shall be accompanied by proposals to adapt this Regulation.]
