In order to further enhance the introduction of the Entry-Exit System (EES), Frontex is planning to test various technical solutions with the aim of advising EU countries on the most appropriate technology to be used. Therefore, Frontex is about to launch procurement procedures to gather industry solutions for the testing and implementation of EES-compliant equipment, including complete technological solutions, hardware and software, and development and integration services with national systems. The EES will register the entry and departure data of non-EU nationals crossing the external borders of EU Member States. For the legal framework, see eucrim 4/2017, p. 164.
