What is Passport Verification and How Does it Work?

Passport verification is a crucial process aimed at confirming the authenticity and validity of a passport. This verification involves a meticulous examination of the information contained in the passport, including personal data, photographs, signatures, and security features designed to prevent forgery or alteration. Governed by international standards, passport verification is commonly carried out by government agencies, border control authorities, immigration agencies, and various institutions. Using passport reader SDK for verification the primary objective is to ensure that the presented passport is genuine, unaltered, and belongs to the individual presenting it. This process plays a pivotal role in maintaining security, preventing identity theft, illegal immigration, and other fraudulent activities.

What Are the Standard Parts of a Passport (TD3)?

A standard passport, adhering to the International Civil Aviation Organization (ICAO) specifications, follows a specific format known as a Size 3 Travel Document, or “TD3.” This format is used globally and simplifies the verification process for passport control officers and specialized OCR data extraction technologies. The main components of a passport booklet typically include the outer cover, holder data page, authority information page, visa pages, and back cover. While passport designs may vary by country, the ICAO TD3 format establishes general standards to ensure worldwide authenticity and interoperability.

What Do the MRZ Fields in a Passport Mean?

The Machine-Readable Zone (MRZ) is a coded area on identity documents, including passports, ID cards, and driving licenses. Each character in the MRZ serves a specific purpose, enabling machines to swiftly verify passport authenticity and match information with visible data. Spanning two lines, the MRZ in the TD3 passport format contains crucial details such as the passport number and expiry date. This coded zone plays a vital role in streamlining passport control processes at various entry points into a country.

What Is Online Passport Verification, and What Does It Consist Of?

Online passport verification is a remote process that utilizes digital tools and services to verify the authenticity and validity of a passport. Unlike manual verification at physical checkpoints, online verification relies on technology and internet connectivity to perform the task automatically and remotely. This process, often providing real-time results, has become standardized in industries and government agencies for digital onboarding processes, ensuring compliance with Know Your Customer (KYC) and Anti-Money Laundering (AML) regulations. The online passport verification process involves reading passport data, verifying passport authenticity, and, in certain cases, employing biometric verification to confirm the identity of the passport holder.

What Security Features Do Passports Have to Prevent Forgery?

Passports incorporate a range of security features designed to thwart forgery and ensure document authenticity. These measures, varying by issuing country, include security printing, ultraviolet and invisible inks, holograms, optical variable elements (OVD), security threads, microprinting, special paper and material, electronic chips, watermarks, and machine-readable zones (MRZ). Modern passports, such as the e-passport, integrate advanced security measures like ultraviolet printing, holographic foils, and NFC chips containing biometric data.

In conclusion, passport verification is a multifaceted process critical for maintaining global security and preventing fraudulent activities. As technology evolves, online passport verification emerges as an efficient and secure solution, integrating advanced features to enhance the accuracy and reliability of the authentication process.

The Role of MRZ in Passport Verification

One of the integral components of passport verification is the Machine-Readable Zone (MRZ). The MRZ, located at the bottom of the passport, contains coded information that is crucial for quick and efficient verification. This two-line code, often in a standardized format, includes essential details such as the passport holder’s name, date of birth, passport number, and expiration date. The MRZ facilitates automated data extraction, streamlining the verification process and reducing the risk of errors.

Online Passport Verification Process

The evolution of technology has paved the way for online passport verification, transforming the way identity is confirmed remotely. This process is particularly valuable in scenarios where physical verification at checkpoints is impractical or inefficient. The online passport verification process typically includes the following key steps:

Reading Passport Data

The initial step involves capturing all relevant information from the passport. This can be done through various means, such as capturing an image with a webcam or a mobile device camera. Optical Character Recognition (OCR) technology is often employed to extract crucial details from the Machine-Readable Zone (MRZ), ensuring accuracy and reliability in the data extraction process.

Verification of Passport Authenticity

Once the passport data is captured, the system performs a comprehensive analysis to validate the passport’s authenticity. This involves scrutinizing security features embedded in the passport, such as holograms, watermarks, and digital alterations. For passports equipped with an NFC chip, the verification extends to confirming the authenticity of the information stored in the chip.

Biometric Verification of Passport Owner

In some instances, biometric verification is integrated into the process. Facial recognition algorithms compare the passport holder’s photograph with a real-time image provided by the individual through a selfie taken with a webcam or mobile device. Face verification adds an extra layer of assurance, confirming that the person presenting the passport is indeed the rightful owner.

Use Cases of Online Passport Verification

Online passport verification has found application in various industries, from airport check-ins to opening online bank accounts and verifying identities in digital services. Its efficiency, combined with the ability to provide rapid and accurate identity verification, makes it a valuable tool across diverse sectors.

Mobbeel Anti-Fraud Security Measures

MobbScan, a solution designed for online passport verification, incorporates a series of anti-fraud security measures. These measures serve two primary purposes: validating the document being used and verifying the identity of the person presenting it. Key components of MobbScan’s security measures include content-based document verification, appearance analysis, file analysis, and dynamic element analysis.

Content-Based Document Verification

MobbScan starts by validating the information within the identity document, ensuring adherence to international standards. This includes verifying check digits, data on both sides of the document, two-dimensional codes, and preventing the use of forged documents.

Appearance Analysis

To detect visual irregularities, MobbScan utilizes computer vision and machine learning techniques. This involves identifying potential issues such as cuts, missing elements, alterations to facial images, and the use of document copies or screenshots.

File Analysis

To prevent tampering with attached documents, MobbScan scrutinizes the image frame for signs of digital editing. By verifying elements like the date of birth, facial image, and personal number, MobbScan alerts users to potential threats.

Dynamic Element Analysis

For enhanced security, MobbScan conducts advanced checks on identity documents with dynamic elements, such as laser marks, kinegrams, or NFC technology. While these checks may impact the user experience, they provide an additional layer of security.


Passport verification, a vital process for ensuring global security, has evolved with the integration of advanced technologies. Online passport verification, facilitated by tools like MobbScan, offers a streamlined and secure solution for identity confirmation in various industries.
