The Barcode/QR Code Scanner component can scan and decode barcodes. Under the hood, the component contains NFIs that use the the Google Mobile Vision: Barcode API. The component also supports continuous scanning and automatic rendering. You can use the component in scenarios such as: An event organizer app, where a user needs to continuously scan barcodes on passes and allow entry to the attendees. A calendar app that adds events to a user's calendar using the QR Code of the event.
