On 18 and 19 October 2022 the Royal Marechaussee, the Dutch military police, will host a Conference on the Entry/Exit System in the Maritime Domain for EU border guard agency Frontex in Rotterdam. The conference will bring Frontex staff, staff of border and port authorities from EU member states and representatives from selected companies and cruise-ship associations together to discuss the implementation of the Entry/Exit System (EES), a biometrics based database, at maritime border crossing points. The EES is part of a network of (biometrics) databases, with the aim to create a ‘virtual wall’ to keep or get migrants out of the EU. These virtual walls connect with the whole system of border walls, border militarisation, border externalisation, detention and deportations the EU has deployed in building Fortress Europe. It is also another profit opportunity for the military and security industry.
