Can I lend my fitness card to others?
Not necessarily. Whether the fitness card can be used by others depends on the strict control of the gym. Some business fitness cards in the gym are allowed to bring friends or family members, and one card can be used by the whole family. In order to prevent users from using more than one card, some gyms will take pictures of the user's head when opening the card for the first time, and display the user information every time they swipe the card. If the avatar is wrong, the cardholder will be refused to use it.
