Interesting, so it doesn't only sync the balance but enables the offline device to function without the Tracking device once it was synced (so it syncs outputs?).
Just want to make sure thats how it works. If yes, I'd like to have another way of syncing it than a Tracking device. Maybe someone from the Developers read this and create something. If not, I can do a web based version that does that if I know how the QR code is build and what information it requires
