Bug 23699

Just a crazy thought, but it could be useful for small libraries or to use a smartphone/tablet as a mobile terminal for librarians.

Use a JavaScript library like quaggaJS [0] to turn smartphone cams (or webcams on notebooks) into a barcode reader.

-) Add an option to the system preferences to enable JS barcode reader (e.g. "Use mobile device cam as barcode reader: disabled | enabled | on mobile devices only | user/session defined ...")

-) If enabled, an additional button (e.g. with font awesome barcode symbol) next to the header search field (e.g. between input form and submit button)

-) The barcode button opens a modal with the barcode scanner to get patron id or item id

-) Also add a barcode button to the checkout field in circulations for reading item barcode.

Example implementations are available at [1] and [2]
