QuaggaJS

+ +

An advanced barcode-scanner written in JavaScript

+
+
+
+

Working with file-input

+ +

This example let's you select an image from your local filesystem. + QuaggaJS then tries to decode the barcode using + the preferred method (Code128 or EAN). + There is no server interaction needed as the + file is simply accessed through the File API.

+ +

This also works great on a wide range of mobile-phones where the camera + access through getUserMedia is still very limited.
