A biometric passport is a travel document with an embedded chip that stores the holder's data. The global rules for these documents are set by the International Civil Aviation Organization.

A biometric passport, also called an electronic passport, carries a contactless chip beneath the data page. The chip stores the same details printed on that page, including the machine readable zone and the holder's photograph, and can hold further biometric data such as fingerprints in some countries.
The chip lets border systems read and verify the document quickly, and supports automated gates at many airports.
ICAO is a specialised agency of the United Nations that standardises international air travel. Its document, Doc 9303, defines the specification for machine readable travel documents used worldwide.
The standard covers the physical layout of the document, security features such as holograms and special inks, the format of the machine readable zone and its check digit method, and, for electronic documents, the chip data structure, the cryptographic protocols, and the biometric specifications for face, fingerprint and iris.
Because most countries follow Doc 9303, a passport issued in one country can be read reliably at borders around the world. This interoperability is what allows automated checks and consistent verification.
The standard is revised over time. Newer editions support updated methods for encoding biometric images, which improves verification while keeping older compliant documents readable.
Passport design, the data stored on the chip and renewal rules are set by each issuing country within the ICAO framework. For the specifics that apply to you, confirm with your national passport authority, and treat the standard summarised here as background information rather than advice.
At minimum the chip holds the same information printed on the data page, including the machine readable zone and the photograph. Some countries add further biometrics such as fingerprints. Confirm what your country stores with its passport authority.
Many countries now issue only electronic passports and some destinations expect them, but requirements vary. Check the rules of both your issuing country and your destination.
The International Civil Aviation Organization sets the global specification in Doc 9303. Each country then issues passports that follow it.
