The new EU Entry/Exit System (EES) has started creating chaos at the Greek border - and the summer season has not even begun. Biometric checks, face scanning, fingerprints - and queues that tourism associations from Macedonia and Serbia are already predicting will be catastrophic.

Macedonian and Serbian tourism associations have requested a temporary exemption from biometric controls during the summer season. Greece responded - but only for the British, who will be exempt from the new system. For Balkan tourists there is no relief so far.

Croatian journalist Sneze Velkov, who tested the system in the field, was blunt about the experience. The question is real: can the EU introduce a security system without killing tourism? So far it looks like it cannot - at least not at the Greek border where Macedonians and Serbs vacation en masse.
