Just like using it for the first time at home, if you want to download the security control, you can download it on the website of Bank of China (you are not allowed to paste the URL here), and then double-click to install it according to the prompt. Generally, Internet cafes are equipped with recovery cards, which can be deleted by restarting the machine (in fact, it is useless not to delete them).
In order to ensure the security of China Bank's online banking, the sensitive information input column of the login page is controlled by the security plug-in. If you have not installed the online banking security control of China Bank or the browser is set to "Do not download and execute ActiveX control" and the security control cannot be installed, you cannot enter the online banking password. To solve this problem, please select "Tools"-> in the menu of IE browser; "internet options"->; "security"->; "internet"->; Customize the level, select Reset to Security Level-in the dialog box, and click Reset to confirm. After setting IE browser successfully, please click the "Download Security Control" link on the online banking login page to download and install the online banking security control.
