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...

Mobile document scanning has become a baseline feature for productivity apps — think expense reports captured from receipts, signed contracts photographed in a meeting room, or ID documents registered at a service counter. Building such a feature from scratch, handling perspective correction, edge detection, and multi-format export, is a significant...

Machine Readable Zone (MRZ) scanning is a critical feature in identity verification, border control, hotel check-in, and know-your-customer (KYC) workflows. Passports and ICAO-compliant ID cards embed personal data in two or three lines of OCR-B printed text at the bottom of the data page — the MRZ. A mobile app...

When evaluating barcode scanning SDKs, you’ll often encounter bold marketing claims: “Scans barcodes from 5 meters away!” or “Industry-leading long-distance scanning!” But here’s the truth that vendors don’t want you to know: distance alone is a meaningless metric. In this article, I’ll show you how to build an iOS app...

Apple’s vision framework provides APIs for performing computer vision tasks such as face detection, document boundary detection, and text extraction. In this tutorial, we’ll explore how to leverage these APIs and Dynamsoft MRZ SDK to build a robust iOS ID scanner app. What you’ll build: A SwiftUI iOS app that...

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...

A Vehicle Identification Number (VIN) scanner application is a useful tool for car owners and car manufacturers, enabling quick retrieval of a vehicle’s unique identifier. In this tutorial, we’ll walk through creating a cross-platform .NET MAUI VIN barcode scanner using Dynamsoft Capture Vision, covering setup, UI implementation, and VIN recognition...

Starting from .NET 9, there is a new HybridWebView control in MAUI which makes it easy to host arbitrary HTML/JS/CSS content in a web view, and enables communication between the code in the web view (JavaScript) and the code that hosts the web view (C#/.NET). In this article, we are...

The Dynamsoft GitHub page provides sample projects for learning iOS development with MRZ (Machine Readable Zone) and VIN (Vehicle Identification Number) scanning. Both sample projects are built using Storyboard. In this tutorial, we’ll use the official source code as a foundation to build an iOS application that supports both MRZ...

In office environments, network-connected physical document scanners from manufacturers like HP , Canon , Epson , and Brother often support protocols such as ESCL (AirPrint) or ICA (Image Capture). However, for scanners that do not natively support these protocols, you can use third-party services like Dynamic Web TWAIN to enable...

In this article, we will explore Dynamsoft’s Ready-to-Use Barcode Scanner API for iOS. We will cover how to integrate the barcode scanner framework, distributed via the Swift Package Manager, into an iOS SwiftUI project, as well as how to customize its functionalities by modifying the source code. This article is...

Machine-readable zones (MRZ) are an essential feature for processing passports, IDs, and other travel documents. In this tutorial, we’ll demonstrate how to build an iOS MRZ scanner app using SwiftUI and Dynamsoft Capture Vision SDK. What you’ll build: A native iOS app that uses the device camera to scan and...

Creating a mobile app that scans and decodes Machine Readable Zones (MRZs) is essential for many industries, including travel, security, and identification verification. With .NET MAUI (Multi-platform App UI), developers can build cross-platform applications for Android and iOS using a single codebase, streamlining development and maintenance. In this tutorial, we’ll...

.NET MAUI simplifies cross-platform app development by enabling a single codebase for multiple platforms. The Dynamsoft Capture Vision MAUI Bundle offers powerful APIs for document scanning, barcode reading, and MRZ recognition. In this tutorial, you’ll learn how to create a .NET MAUI document scanner that can capture, normalize, and share...

Exchangeable image file format (officially Exif) is a standard that specifies formats for images, sound, and ancillary tags used by digital cameras (including smartphones). It contains metadata like camera parameters, image dimensions, and image orientation. Most camera sensors have a shape where its width is larger than the height. If...

Recently, Dynamsoft released a new .NET MAUI Barcode SDK for building barcode scanning applications on Android and iOS. In this tutorial, we will use Visual Studio Code to create a .NET MAUI Barcode Scanner from scratch. Our application will decode barcodes and QR codes from both image files and camera...

Sometimes, we may need to merge multiple images into a single PDF file. For example, we scan the front side and the back side of an ID card and want to store them in a single PDF file. In this article, we are going to talk about how to build...

Barcode scanning is an essential tool for modern inventory management. It improves accuracy, efficiency, real-time tracking, and cost savings, making it a critical component of any effective inventory management system. In this article, we will build a Flutter barcode scanner capable of simultaneously reading multiple 1D barcodes, QR codes, and...

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...

Dynamsoft Document Normalizer is an SDK to detect the boundary of documents and runs perspective transformation to get a normalized document image. In this article, we are going to build an iOS document scanner using Dynamsoft Document Normalizer and AVFoundation. A demo video of the final result: The scanning process:...

The MediaDevices.getUserMedia() API is the standard way to access cameras from web browsers. While it’s relatively straightforward, building a complete web camera viewer still requires significant effort. Until recently, there were no ready-to-use JavaScript camera widgets. However, with the release of the Dynamsoft Camera Enhancer library, implementing a browser-based camera...
