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
For ourputs, the hardbit is generating a QR code (the signed transaction) and you have to scan it to propagate the transaction using your smartphone.
I agree that a web based version would be nice (something like

I meant output as in output of a previous transaction, not the output of the device.
Like the outputs you need in order to create valid transaction. But I think that got answered as well as you said it can create transactions (instead of just singing them like with an armory offline wallet?).
So what you need is something or someone to take the hardbit created signed Tx and broadcast it? That can be some by a webcam on a computer or the merchant then. Hope this kind of bitcoin storage will become more popular as it's really easy to use and allows for fast payments as brick and mortar stores. I also hope it will become common to take send those Transactions for the customer so people like me who don't carry tracking devices can still pay.
I am looking forward to the translation of the technical details and hope it really works the way I now think it does.
