context_page_description: A passport is a travel document, usually issued by a country's government to its citizens, that certifies the identity and nationality of its holder primarily for the purpose of international travel. Standard passports may contain information such as the holder's name, place and date of birth, photograph, signature, and other relevant identifying information.
  Many countries have either begun issuing or plan to issue biometric passports that contains an embedded microchip, making them machine-readable and difficult to counterfeit. As of January 2019, there were over 150 jurisdictions issuing e-passports. Previously issued non-biometric machine-readable passports usually remain valid until their respective expiration dates.
  A passport holder is normally entitled to enter the country that issued the passport, though some people entitled to a passport may not be full citizens with right of abode. A passport does not of itself create any rights in the country being visited or obligate the issuing country in any way, such as providing consular assistance.
context_section_description: The International Civil Aviation Organization (ICAO) issues passport standards which are treated as recommendations to national governments. The size of passport booklets normally complies with the ISO/IEC 7810 ID-3 standard, which specifies a size of 125 × 88 mm (4.921 × 3.465 in). This size is the B7 format. Passport cards are issued to the ID-1 (credit card sized) standard.
  A standard passport booklet format includes the cover, which contains the name of the issuing country, a national symbol, a description of the document (e.g., passport, diplomatic passport), and a biometric passport symbol, if applicable. Inside, there is a title page, also naming the country. A data page follows, containing information about the bearer and the issuing authority. There are blank pages for visas, and to stamp for entries and exit. Passports have numerical or alphanumerical designators ("serial number") assigned by the issuing authority.
  Machine-readable passport standards have been issued by the ICAO, with an area set aside where most of the information written as text is also printed in a manner suitable for optical character recognition.
  Biometric passports (or e-passports) have an embedded contactless chip in order to conform to ICAO standards. These chips contain data about the passport bearer, a photographic portrait in digital format, and data about the passport itself. Many countries now issue biometric passports, in order to speed up clearance through immigration and the prevention of identity fraud.  These reasons are disputed by privacy advocates.
