Does each person playing needs the $5 membership card or only one in the group?

Everyone.

Everyone swinging a club in the bay needs to have a player card. They are 5.47 per person after tax.

Each guest playing the game of Topgolf must have a membership card! This is a one time purchase of $5 that lasts a lifetime.

When I went it was free membership. Call to verify

Everyone needs a card. It is how score is tracked.

Everyone playing. If your not golfing, your exempt from the membership fee.
