I have experienced ICBC's online banking, which also appeared in 100 19. The customer service calls made by ICBC for many times have not been resolved. Then I read a book, and I was all thumbs until I took it out. Please refer to whether yours is ok. There is an IE option in the drop-down menu of IE tool. Open it and enter the "Contents" tab. There is a Certificate button in this Content tab. Click "Open" to import your personal certificate and bank certificate again. At that time, I imported all the bank certificates into each tab at once, which was very easy to use. You try.
