Machine readable zones have revolutionized the way identity verification is conducted, offering several advantages over traditional manual methods.

MRZ Meaning: What Are Machine Readable Zones?

What is MRZ? Machine Readable Zones (MRZs) are standardized areas on passports, national ID cards, and other travel documents that contain essential personal information encoded in a specific format. This format allows automated systems to quickly and accurately read and verify the information, making it a crucial tool in identity verification.

The purpose of Machine Readable Zones is to provide efficiency in service delivery, expedite the identity verification process and reduce manual labor and errors. It also provides accuracy as the standardized format minimizes the risk of human error in data entry.

MRZs can help prevent fraud by making it more difficult to counterfeit or alter documents.

Difference of MRZs From Human-Readable Information:

Unlike human-readable information, which is designed for human eyes, MRZs are optimized for machine interpretation. They use a specific font and layout that can be easily scanned and processed by automated systems. Human-readable information, while essential for human understanding, may be more susceptible to errors or alterations.

How Do Machines Read MRZ Codes?

Machines read mrz codes through the following ways:

1. Optical Character Recognition (OCR): This technology is commonly used to read MRZ codes. OCR systems can accurately recognize the characters in the MRZ, even if they are partially obscured or damaged.
2. Barcodes: Some MRZs may also include barcodes, which can be read by barcode scanners. Barcodes offer a more compact and efficient way to store information, but they may not contain as much detail as OCR-readable text.

To extract and verify data from these zones, the machine uses the following: 

1. Scanning: The MRZ is scanned using an appropriate device, such as a passport scanner or a mobile phone with a built-in scanner.
2. Data Extraction: The scanning software extracts the encoded information from the MRZ and converts it into a digital format.
3. Data Validation: The extracted data is checked against predefined rules and databases to ensure its accuracy and consistency. This includes verifying the format of the information, checking for inconsistencies, and comparing the data against known databases of lost or stolen passports.

What are the Types of Machine Readable Zones?

There are two primary types of machine readable zones they include the Type A and Type B:

1. The Type A Machine Readable Zone

Uses a format of two lines of text containing 42 characters each. The content on the zone usually includes personal information such as name, passport number, date of birth, nationality, and passport expiration date. It is commonly used in passports and national identity cards.

2. The Type B Machine Readable Zone

This zone is formatted in three lines of text, with the first line containing 30 characters, the second containing 23 characters, and the third containing 7 characters. It contains content including similar information to Type A MRZs, but with a slightly different format. It is less commonly used, but can be found on certain travel documents.

What Are The Key Differences Between Type A and Type B Machine Readable Zones?

The key differences between the Type A and Type B Machine Readable Zones includes the following:

• Format: Type A MRZs have a more compact format with two lines, while Type B MRZs have three lines.
• Content: While both types contain similar information, there may be slight variations in the specific fields included.

Uses Of Both MRZ Types In Various ID Documents

Most passports use Type A MRZs, but some countries may use Type B. For National identity cards, Type A MRZs are the most common type used. Other travel documents, such as visas and travel permits, may also use MRZs, but the specific type may vary depending on the issuing authority.

Though these types may differ in their format and content, they serve the same purpose of providing essential information for efficient identification.
