Just like ESTA, ETA and other electronic visas, the EU is now also rolling out an electronic travel authorisation for travellers that are not part of the EU but are eligible for visa-free travel to EU and Schengen countries.
ETIAS means EU Travel Information and Authorisation System. It was designed to increase the security of visa-free travellers visiting the EU for different purposes as for example: tourism, business, transit or medical reasons.
The ETIAS will be mandatory for travelling to the EU and Schengen area and it can be purchased online, the application process is very quick and easy and has to be completed prior to your arrival in the EU.
