Can I still give away the password of the crab card if it is scraped open?

Can't give it away. Crab card is a kind of gift card, which usually has some scratched passwords or verification codes. Once these passwords or verification codes are scraped off, they cannot be used again. This is because these scraped passwords or verification codes are designed to be used only once, and once used, they cannot be used again. So I can't give it away.
