Everyone owns a passport, and yet few people know definitively what rights they actually receive with their passport, which is part of the impetus behind 'Passport Index.' The online tool from financial firm Arton Capital is essentially an online encyclopedia of passport laws, rights and powers organized by nation.
Passport Index has a slick, attractive interface that lets users click on images of passports to read about their rights. The power of each passport is ranked on the site through a measure called "visa-free score," or VFS. The VFS is based on things like access to foreign countries, visa-free mobility, and short stay privileges. According to the database, the most powerful passports in the world are German and Swedish, while the least powerful is Afghanistani.
