Adding someone to Card but not the Board?

[Rachel Dennis]

Is there anyway to do this?  We need to keep confidential items safe, but need to add people to a specific card.  Is there a way to add someone to a card but not allow them to be a member of the board/able to see other lists and cards?

Hey @Rachel Dennis 

When you invite someone to a card they have to be a member of the board, this is so that we can use the board's permissions to make sure they're allow to access the card.

If you're wanting to give someone access to certain pieces of information without granting them access to others, the best thing to do will be to split this information across multiple boards so that you can invite someone to only the boards with the information they need access to.
