Many countries normally allow entry to holders of passports of other countries, sometimes requiring a visa also to be obtained, but this is not an automatic right.
Many countries are moving towards including biometric information in a microchip embedded in the passport, making them machine-readable and difficult to counterfeit. We’ve even got a full range of hybrid bikes (perfect for commuting), which includes several folding bikes – ideal if you’re taking the train or you’re short on storage space. Pop into one of our UK bike stores where our friendly staff will help, or use our super handy right bike finder tool. Or if it’s all about tracks and trails, head to our mountain bikes for a mix of hardtail and full suspension machines.For example, stateless persons are not normally issued a national passport, but may be able to obtain a refugee travel document or the earlier "Nansen passport" which enables them to travel to countries which recognise the document, and sometimes to return to the issuing country.Passports are often requested in other circumstances to confirm identification such as checking in to a hotel or when changing money to a local currency.ICAO standards include those for machine-readable passports.Such passports have an area where some of the information otherwise written in textual form is written as strings of alphanumeric characters, printed in a manner suitable for optical character recognition.In the later part of the nineteenth century and up to World War I, passports were not required, on the whole, for travel within Europe, and crossing a border was a relatively straightforward procedure.Consequently, comparatively few people held passports. During World War I, European governments introduced border passport requirements for security reasons, and to control the emigration of people with useful skills.In the medieval Islamic Caliphate, a form of passport was the bara'a, a receipt for taxes paid.Only people who paid their zakah (for Muslims) or jizya (for dhimmis) taxes were permitted to travel to different regions of the Caliphate; thus, the bara'a receipt was a "traveler's basic passport." In medieval Europe, such documents were issued to foreign travelers by local authorities (as opposed to local citizens, as is the modern practice) and generally contained a list of towns and cities the document holder was permitted to enter or pass through.
