I use Bank of China, it is very easy to use and convenient
When logging in for the first time, you need to download the security control, then use the original password to log in to online banking, and then change the user name and password. On the online banking page, there is a place for activating online payment and other similar options. Click to activate, and then you can make payment.
After taking pictures of stuff on Taobao, select online banking----Bank of China in the payment method
It will automatically jump to the Bank of China page, enter the modified user name and After the password is correct, it will show you to enter the dynamic password (the number on the electronic key), finally select the card (mine is the Great Wall debit card), submit and the payment will be successful.
