The passport machine readable zone code 2D scanner is a device used to read the passport machine readable zone information. The machine-readable zone of a passport usually contains the passport holder's name, nationality, date of birth, gender, passport number and other information.

Passport information can be read quickly and accurately using a two-dimensional passport machine readable zone code scanner and input into the computer system for processing. This kind of equipment is usually used in airports, customs, hotels and other places to quickly process the entry and exit procedures of passengers.

Two-dimensional scanners usually use image processing and computer vision technology to convert the machine-readable zone information on the passport into digital signals and transmit them to the computer system for processing. This information can be used for identity verification, data statistics, itinerary management and other purposes.

It should be noted that when using a passport machine-readable zone code 2D scanner, relevant privacy policies and data protection regulations should be followed to ensure the security and privacy of personal information. At the same time, for some countries or regions with special regulations, specific equipment or programs may be required to read passport information.

A passport is a legal document issued by the country to prove the nationality and identity of a country's citizens when they enter and exit the country's borders and travel or reside abroad.

The word passport means port pass in English. In other words, a passport is a form of identification that allows citizens to travel through international ports in various countries. Therefore, some countries in the world usually issue pass documents in lieu of passports.

Currently, the passports issued by most countries in the world can generally be divided into three types: diplomatic passports, official passports and ordinary passports; some countries only issue one kind of passport (such as the United Kingdom); a few countries issue two passports (such as India and Pakistan, etc.) ; Some countries issue four or five types of passports (such as the United States and France, etc.).

Passport numbers are not uniform around the world. Passport issuance is a country's internal affairs. The style and design, including passport number encoding rules and passport types, are determined by the country itself. There is no need to communicate with other countries in advance. Usually, it only guarantees that the number is unique among the documents issued by it. There is no unified agency/mechanism in the world that allocates passport numbers to all countries.
