This tutorial demonstrates how to build a cross-platform identity verification tool using .NET MAUI and the Dynamsoft Capture Vision SDK. By utilizing a single codebase, developers can create MRZ scanners for both Android and iOS that capture camera input, process video frames, and accurately decode identity data from passports and ID cards in real time. This approach significantly streamlines development by eliminating the need for platform-specific UI implementations. The solution ensures high accuracy by employing multi-frame cross-verification, which reduces false positives by confirming MRZ strings across consecutive frames. The architecture seamlessly integrates camera enhancement with text recognition, automatically parsing ICAO 9303-compliant documents into structured fields like name, nationality, and expiry dates. This reliability is crucial for security applications where data integrity and speed are paramount. This article is relevant to open data as it illustrates how to standardize the extraction of identity information from physical documents into digital formats. By making MRZ data machine-readable and accessible via open development frameworks, it facilitates the integration of verified personal data into broader information systems. This supports initiatives for digital identity management and efficient data sharing, provided ethical standards and privacy regulations are strictly followed during the digitization process.
