Starting tomorrow foreigners traveling to Europe will have their fingerprints scanned and picture taken when they arrive in 28 EU nations under new regulations. Those who don’t provide such biometric data will be denied entry.

The change comes as the European Union rolls out its new Entry/Exit System for not just Americans but all visitors from outside Europe’s Schengen Area, a group of countries that allows people in the zone to travel across borders freely without going through customs checks.

The new system will be introduced gradually over a roughly six-month period starting Oct. 12. It will eventually replace passport stamps, according to the EU.
