How to Build a React Native MRZ Passport Scanner for Android and iOS

Verifying travel documents manually is error-prone and slow. The Machine Readable Zone (MRZ) printed on passports, ID cards, and other ICAO-compliant travel documents encodes all key identity fields in a structured, machine-readable format — but extracting it on mobile requires both an accurate OCR engine and a live camera pipeline. The Dynamsoft MRZ Scanner SDK wraps both into a single React Native call that works on Android and iOS. What you'll build: A React Native app (Android API 21+ / iOS 13+) that opens a live camera scanner, reads the MRZ from any TD1/TD2/TD3 travel document, and displays the parsed fields — name, document number, nationality, dates — using dynamsoft-mrz-scanner-bundle-react-native v3.2.5002.
