The idea is following: You first print the frontside with the public key, then you flip the outprint and put it back into the printer and then print the backsite with the private key. There is a sophisticated folding method for this wallet. The foldingsteps are described on the backsite.
I am very sorry, that you don't like the design, CoinBand.
What exactly can be improved?
I think it is secure msc_de, because the html with the outprint is fully useabel after going offline. It is a pity, that criminal hackers are attacking Bitcoin so much. I agree, that printing the wallet during being online is a bit risky. I also think that if one wants to be totally secure he should delete the browser chronik after printing and maybe other data storages, e.g. of the printer. But I am not an expert in this area. Maybe it is helpful if you could share a bit of your knowledge about security, msc_de.
