### 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.
