The binding card of the smart canteen does not necessarily need to be recharged in the park card. The reason why the binding card of the smart canteen does not necessarily need to be recharged in the park card is because the smart canteen can accept other ways of recharging. Different smart canteen systems have different functions and needs, some accept the recharge of third-party payment platforms such as Alipay and WeChat, and some only accept the recharge of designated recharge outlets in the park.
