The purpose of this paper is to explore whether the processing of personal data under Regulation 2017/226 is compatible with the principle of proportionality in the light of Charter of Fundamental Rights of the EU and the case-law of the Court of Justice of the European Union (CJEU). The Regulation 2017/2226 provides the EES system which is the only system that collects the entry/exit data of all third-country nationals entering the Schengen area for a short stay, whether via a land, sea or air border. The EES replaces the current system of manual stamping of passports.
