How to Enable QR code Scanning from Mobile Cameras in Web

You have a requirement to enable web-based barcode scanning for your mobile browsers. But, you don’t want to do it via an app since it requires extra effort for both users and developers. How do you build an online QR code scanner using mobile camera? There are mainly two ways to decode barcodes in mobile browsers:
-
Client-Side scanning
-
Server-Side scanning
In this post, we introduce a solution for barcode scanning from mobile browsers.

With the JavaScript SDK, you can easily integrate barcode and QR code scanning into your browser-based workflow. On mobile phones, your customers and employees will no longer have to download an app.
Read Barcodes on Server Side
Users can access the web page via their mobile browsers, capture an image or load an existing one, upload it to the server, and the server will decode the barcode content, and then return the decoded result.
