You download the security control first, then download the driver of your brand U shield, log in to the personal bank (online), click U shield management, then download the certificate or something, plug in the U shield, and then enter the U shield code. Just get one yourself, click download, and a pin code will appear (indicating almost success). Pin code is the previous U shield code.

The above is the first time to use the U shield, mainly to put the certificate in your U shield. When you use it again, if you change a computer, you must install the security controls and drivers, and then plug in the U shield when you pay.
