Wechat has very powerful functions, such as using the WeChat official account of Wechat to bind the bank card for business, just like the small program of Industrial and Commercial Bank of China, where you can bind the card and conduct basic business. Then, if you don't use it anymore, you want to untie it, but some people can't operate it.

Let's take the problem of unbinding bank cards of China Industrial and Commercial Electronic Bank in Micro-WeChat official account as an example to explain the steps. I hope I can help you to operate Huawei mobile phones.

1. Open the WeChat APP, click WeChat in the lower left corner and search for "China Industrial and Commercial Bank Electronic Banking" WeChat official account. Click Enter.

2. Then click "I" in the lower right corner of the electronic banking page of China Industrial and Commercial Bank, and a menu will pop up. Click Bank Card Binding.

3. Then a pop-up window will pop up, and click "Allow" to log in.

4. Then you can see your account, and click the place indicated by the arrow to enter.

5. Then enter the specific message of the bank card and click the Unbind button.

6. At this time, a pop-up window will pop up, prompting to ask whether to unbind. Click Unbind.
