The card opening time of fitness card is generally calculated according to the date when members first arrive to enjoy the service or put forward activation. Some fitness companies will automatically open cards to calculate the time within a certain period of time. In most cases, you need to wait until the member arrives for the first time to enjoy the service, that is, activate the fitness card. The specific card opening time and method need to be determined according to your contract with the fitness company and the service policy of the fitness company. I suggest you consult the terms of the contract or the fitness company for accurate information.
