Jan, at Bitcoin 2013, you talked about the ability to sweep in amounts you kept in a QR code in your physical wallet and change directly back to the physical wallet... when do you think this feature will be more automated in mycelium?
Can you elaborate on this? Right now you can add keys to addresses and spend form it. How would you envision the perfect user interaction for physical paper wallets?
Sweeping addresses has some slightly distinct use. Imagine you receive a bit-bill and want to make sure, nobody else receives it. You would scan it, but never actively use the address after receiving what was in it this moment. An advanced option would be, to also in the future sweep what is received with it, instantly, but that would surely not be a free service.
