The benefits of binding a credit card to WeChat are:

1. Follow the bank's official account through WeChat, and you can receive free credit card transaction reminders, making it easy to keep track of changes in funds at any time.

2. After binding a credit card, you can directly increase the limit of the credit card through the WeChat official account.

3. After binding the official account, you can check the bill at any time and make repayments.

4. Another advantage is that you can directly participate in various card swiping activities organized by major banks, and you can always pay attention to the latest activity status.

If there is a downside, if WeChat is accidentally stolen, there may be a risk of credit card swiping.
