"The basic idea behind open source is very simple. When programmers on the Internet can read, redistribute, and modify the source for a piece of software, it evolves.

- You don't need to type anything (except the optional password), so it's not vulnerable to keyboard malware.

- 2FA: Option to enter a password (or more than one to create secondary wallets) besides the deck itself.
- Obscurity: An attacker won't know there are bitcoins in that deck, even if they find it.

- Enter every card on the app.
- Optionally enter a password you won't forget (it's not possible to recover it!).

- Optionally, copy the order of the cards into another deck, as backup.
