Browser Document Capture: A Step-by-Step Guide

Are you eager to streamline document capture directly within your browser? Look no further! In this comprehensive guide, we’ll walk you through setting up a basic lens for a web application that efficiently extracts data from documents using Verify Lens. Let’s dive in.

Step 1: Authentication Credentials

First, ensure you have your authentication credentials ready. By signing into the API portal and accessing Settings > Keys, you can obtain your client ID, username, and API key.

Step 2: Choosing the Method

For seamless document capture within the browser, we’ll be utilizing WebAssembly (WASM) for Verify Lens. WASM stands out for its speed, accuracy, and ability to process frames directly on the client side.

Step 3: Installation

1. Begin by installing Node.js to facilitate the process.
2. Next, download the Verify Lens WASM package from GitHub.
3. If you’re not employing bundlers, ensure to move the package into your project’s folder.

Step 4: Project Setup

1. Copy the wasm directory from the SDK folder to the root of your project.
2. Integrate a <div> with the ID verify-container into your HTML file. This element will dynamically display the lens view.

Step 5: Server Setup

Copy the provided server code into your server.js file. This basic Node.js server effortlessly redirects to index.html.

Step 6: Initialization

1. Import the SDK into your index.js file.
2. Configure the processing URL and credentials for authentication.

Step 7: Launching Lens

Initiate document capture effortlessly by calling the verifyLensInitWasm() function. Capture images seamlessly with verifyLensCaptureWasm().

Step 8: Processing the Image

Once the document is captured, submit it for efficient processing using the processImage() function, along with the necessary arguments.

Step 9: Displaying Results

Display the processed data, typically in JSON format, directly on your web page for enhanced user interaction and convenience.

Conclusion

Congratulations on successfully setting up a basic lens for your web application to streamline document capture using Verify Lens. With fast and accurate processing capabilities, you can enhance workflow efficiency and provide an exceptional user experience.
