Investigate better options to enter paper key (24 words)

[i1skn]

During the initialization of the new wallet - user enter 24 words (paper key) manually. This approach has one big advantage - 100% sure that the user has correctly wrote down paper key. But it also has some disadvantages:

• It is a lot of typing (all 24 words)
• Possible typos (see the Check typos in paper key (24 words) during create/restore wallet #41 )

The research is needed on how can we mitigate these disadvantages and still be "very" sure, that the user has correctly wrote down paper key.
