Supplementary information:
Coin Pass is the latest function of WeChat, which is similar to Yu 'ebao: users can directly use the money in the coin pass 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.
Bitcom is a basic service account of WeChat payment alongside "Coin". Users can access it directly through WeChat-Wallet-Coin-Shit Coin to manage money with small change. Users can transfer money from WeChat change or bank debit card to change money, and all funds of change money can also be transferred to WeChat change or bank card, and there is no handling fee for transfer.
