First, we open the WeChat software, and then enter my options, and you can see my bank card.

Then after we enter my bank card option, we can click Add Bank.

Then we need to fill in the payment password, as shown below (if you forget the password, you can bind the bank card to solve it).

At this time, we need to fill in the name and card number of the cardholder of the bank card, and then click Next.

Then we need to fill in the mobile phone number again, and then click Next.

The last line of cards to be bound needs SMS confirmation. At this time, our mobile phone will receive a verification code. At this point, after we fill in the verification code, we can click Next.
