Excuse me, did you sign the online banking contract at our counter? Do you use our online banking signing account when trading? When you use an online banking signing account to conduct online transactions, the system needs to verify your certificate. After you successfully sign an online banking contract, you must log in to www.ccb.com, the website of CCB, using your personal computer within seven days, and click "Online Banking Service"-"Login" at the top left of the homepage to successfully log in to personal online banking to download the certificate. Please take the following measures to adjust the computer settings before downloading the certificate: open the browser, in the top tools menu-select Internet options-delete: history, temporary files, Cookies, offline web pages, etc. In general, set the web page update to automatic, enter security at the same time, and change all ActiveX controls and plug-ins above the script to custom level to enable. At the same time, select Close from the Pop-up Blocker in the Tools menu. Finally, it is recommended that you temporarily close all interceptors such as online assistants during the operation. After modifying all the settings, please follow the following steps: 1. If you bought our dynamic password card when signing the contract, but didn't buy the USBKEY, you can download the certificate directly without setting the transaction password after logging in: (1) Click the red letter on the right side of the interface to get the verification code, and after the mobile phone receives the verification code, enter the verification code (PHS users should first call local 95533 to ask PHS how to receive the certificate verification code); (2) Select "certificate storage medium" and store it in "local hard disk" to download the certificate to the computer browser; (3) Then set the certificate. If the certificate is set to "Can export private key", you can export the certificate for future backup. If the certificate is set to "private key cannot be exported", the certificate can only be used on this computer in the future, and the backup cannot be exported. It is recommended that you set it to "Private key can be exported" for future backup; Click Next, and your certificate number and expiration date will be displayed. Click Finish, and the signing process is complete. You can log in to online banking and conduct online banking transactions as a contracted customer. 2. If you purchased the USBKEY when signing the contract, please download the certificate to the new USBkey according to the following steps: (1) Install the USB key software program first (please uninstall the computer that has installed the CCB USB key software program and management tool software, and then restart the computer. There is no need to install USBKEY software program. ): put the CD in the USBkey box into the computer drive. After the CD is running, the USBkey installation menu will appear. First, choose whether to install system patches according to the computer settings. If you need to install a system patch, you need to restart the computer after installation. If you don't need to install a system patch for your computer system version, you can directly put it into this CD-ROM and click "Install USBkey Software". The system will automatically install the certificate management tool. (You can also log in to the personal online banking system, select the software download function in the security center menu, and click to download the USBKEY management tool of the corresponding brand. (2) Exit the CD, close all browsers, and insert the diskless USBkey into the USB port. Please modify the initial password of USBKEY through the certificate management tool first. The initial password of USBKEY is: 12345678. You can set your own USBKEY password with 6- 10 characters. After the modification is successful, please open the browser again, log in to personal online banking, and enter the user nickname/ID number, login password and additional code in turn in the login interface as required. After logging in to online banking, please set the online banking transaction password according to the prompt (if the dynamic password card is bound, it is not necessary to set the transaction password); Then download the certificate according to the interface prompt: you don't need to get the verification code here. Please select the corresponding U-KEY brand (such as G&D, Miqi and Huada) in the column of Certificate Storage Media, and the column of certificate setting will automatically default to "Private key is not exportable". You cannot select "Private key is exportable" (Please note! This is the default, not the customer's free choice! ) and enter the USBkey password. After success, the "Finish" interface will appear, prompting the ID number and expiration date. Click it to complete the certificate download. At this point, after the signing process is completed, you can log in to online banking and conduct online banking transactions as a signing customer. When you make online payment, transfer and remittance through our online banking, you need to enter the passwords on the dynamic password card in turn, and each password can only be used once. The last password of the dynamic password card cannot be used for transaction, and can only be used when the user changes the card. The personal online banking dynamic password card entered the wrong dynamic password five times in a row or cumulatively on the same day, and the dynamic password card was locked, and the system automatically unlocked the next day. If you enter an error again the next day after locking, so that the number of consecutive incorrect entries reaches 8 times in two days, the customer dynamic password card will be locked again, and this situation cannot be unlocked.
