Invented by Arton Capital, the Passport Index has become the world's most popular global mobility intelligence platform providing interactive travel requirements and the ability to compare, rank and improve passports based on their mobility scores. Visitors can dive in the fascinating world of passports, explore their designs, sort them by country, region and even by color. For the first time ever, visitors can compare passports side by side and even explore how they can improve their Global Mobility Score by adding additional passports. The Passport Index also features PASSE/PORT, the comprehensive blog curating passport-related news, and views on global mobility, security, technology, branding, and visa policies from around the world.
