In terms of fitness, fitness cards are divided into annual cards, monthly cards, season cards and supplementary cards. If you can persist, the annual card is the most suitable.
You need a fitness card to go to the gym. There will be a machine at the front desk of the gym. Every time you go in, brush it on the machine and you can go in for exercise. Swiping your card will show when or how many times your card has expired, and it will also show your avatar to see if it is you.
