The change pass is supported by Tencent Wealth Management and Weizhong Bank. It is a platform for Tencent to cooperate with many financial institutions to provide users with diversified financial services. Users can directly use the money in the change account for consumption, such as transferring money, issuing red envelopes, scanning code payment, and returning credit cards. At the same time, when the funds in the change account are not used, the income can be automatically obtained.
