Unlimited flow. In order to avoid the cashier fee of Meituan, it may affect the current limit of Meituan's collection by other means. In order to ensure the security and stability of transactions, Meituan will restrict the transactions of merchants, that is, limit the transaction volume of merchants within a certain period of time, so as to avoid excessive transactions leading to system collapse or increasing transaction risks. If merchants use other channels to collect money, such as WeChat, Alipay, etc., these transactions will not be monitored by Meituan system, which may cause the transaction volume of merchants to exceed the current limit, thus being automatically blocked or restricted by Meituan system. In addition, merchants using other methods to collect money may also violate the relevant regulations of the US Mission, such as violating the provisions of the US Mission's collection method, which may lead to penalties for merchants. Therefore, it is suggested that merchants use Meituan's payment method on Meituan platform to avoid affecting the security and stability of transactions.
