What is the machine readable zone in passports?

The machine-readable zone (MRZ) in passports is designed to provide a standardized format for the easy and quick reading of important information by machines. This area typically consists of two or more lines of text printed in a specific font and layout that can be scanned by automated systems at border controls and airports. The MRZ contains key identification data about the passport holder, such as their name, date of birth, passport number, and nationality, ensuring that this information is consistently formatted across different countries.

This standardization is vital for enhancing security and facilitating the processing of travelers, allowing immigration officials to swiftly and accurately verify the identity of individuals using their travel documents. By adhering to international standards, the MRZ helps improve interoperability between different countries' border control systems and enhances overall international travel security.
