When multiple devices are being used in the field without service, this feature would enable the future joining of related data collected simultaneously without syncing. While editing or after creating a new entry, this feature would allow the convenient generation of a QR (or other bar) code corresponding to the entry's fulcrum_id. Another device running a separate fulcrum app could then populate a field (e.g. fulcrum_parent_id) by scanning the qr code, allowing these data to be joined later in situations where syncing is not immediately available. Note, this can already be done if a team prints out a set of unique IDs in a QR/bar code format, where both devices scan to populate a field used to join these data later. This simple feature would reduce the work by one step, using IDs already associated to the data in one device.
