Verifying a passport or ID card on a phone usually means reading the Machine-Readable Zone (MRZ) at the bottom of the document. The MRZ encodes the holder’s name, document number, nationality, and dates in a fixed format that OCR alone cannot reliably parse — you need a recognizer trained on...

Scanning barcodes in an Expo app usually means installing a React Native plugin that wraps some native decoder. This sample takes a different route: the native bridge is written by hand inside the app as a local Expo module, so the app talks directly to the Dynamsoft Capture Vision native...

Choosing the right cross-platform framework for a mobile barcode scanning app means weighing API ergonomics against rendering performance and developer experience. This article compares React Native, Flutter, and .NET MAUI side by side on Android and iOS, each integrated with the Dynamsoft Capture Vision SDK, to show how they differ...

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....

Turning a phone camera into a reliable document scanner requires accurate edge detection, perspective correction, and clean image output — all in real time. The Dynamsoft Capture Vision React Native SDK handles the heavy lifting, letting you ship a cross-platform document scanner for Android and iOS without writing any native...

Building a barcode scanner app is one thing, but creating an intuitive user experience with real-time visual feedback is what sets great apps apart from the rest. In this comprehensive tutorial, you’ll learn how to enhance the basic Dynamsoft React Native barcode scanner sample by adding dynamic visual overlays that...

Identity documents are adopted in many countries to prove a person’s identity. They usually have a card design around 8.6 cm x 5.4 cm in size with three-line MRZ, like ID cards in Germany and the Netherlands. Dutch ID Card Specimen: In this article, we are going to talk about...
