By this way you can sync the balance of the wallet, propagate a transaction and create a backup of the wallet.
Sync the balance of which wallet? The offline one of the one on your Tracking device (Smartphone?)?
If it is the offline device, does that mean you can then create Transactions with only the device without having a Tracking device with you? (As you already have everything needed for creating a Tx then). And do they offer a way to sync it without having a tracking device (a software or a website)?
Sync the balance of the offline device (the device prevents you from creating a transaction if the payment amount is bigger than the balance, so you have to sync the balance when you receive bitcoins on the hardbit address)
