How to verify the gym annual card?

I work in Shenzhen Haofan Fitness Club and we are going to take a membership card. When we come in for fitness, we need to swipe our cards to verify whether our avatars match, so it is basically impossible for anyone except myself to take your card to exercise, but occasionally we can mix it twice, but it will definitely be found out. . . But I don't know what the gym is like there. When you apply for a card, ask what is going on, not the real purpose. For reference. . .
