/**
 * When a code is recognized, this service:
 *
 * [1] triggers the event "$vision.onscan" with the following payload:
 *
 * {
 *   "$jason": {
 *     "type": "org.iso.QRCode",
 *     "content": "hello world"
 *   }
 * }
 *
 * the "type" attribute is different for iOS and Android. In case of Android it returns a number code specified at:
 *  https://developers.google.com/android/reference/com/google/android/gms/vision/barcode/Barcode.html#constants
 *
 * [2] Then immediately stops scanning.
 * [3] To start scanning again, you need to call $vision.scan again
