Hello, dear. I am glad to answer your question about how ICBC app pays the maintenance fund. The payment method of the pro-ICBC app is as follows: 1. Download the APP on your mobile phone, China Industrial and Commercial Bank. 2. Go to the application homepage and open all applications. 3. ICBC e Social Security was launched. If you can't see this application, you can also search directly on it. 4. Bind the personal electronic social security card and click Insurance Payment. 5. Enter personal name and ID number in turn, and select insurance. By default, it is medical insurance for urban and rural residents. 6. Open the medical insurance for urban and rural residents, select the endowment insurance for urban and rural residents below, and click OK. 7. After entering the payment page, you can choose different grades of pension payment, and finally click Pay.
