The financial management method of WeChat payment can be said to be similar to Alipay, and WeChat change pass is equivalent to Alipay's "balance treasure"; WeChat financial management is like Alipay's "wealth". Although the WeChat change pass is docked with four money funds, after the user chooses one as the change pass when purchasing, as long as it is not converted, it will always hold and buy this one in the future. If you are not satisfied with this fund, you can choose to change funds, but you can only hold one of them as an exchange. The card can be paid immediately, and T+0 can also withdraw 1 10,000 yuan. So it is very suitable for storing pocket money.
