Those who have reached the age of 18, stable income and good credit can apply for CCB credit card. At present, there are two main application methods, one is online application, and the other is online application. Online application, the procedure is relatively simple, and no additional financial proof is needed. Banks will focus on the landlord's real estate, social security, provident fund, individual tax, personal credit and other information that can be queried online. There is a bank shield of CCB (like a USB flash drive), which can be approved within five working days at the earliest, without face-to-face signing. If there is no online silver shield, it usually takes about 10 days for approval, and then bring your ID card to the outlet for face-to-face signing. This method is not recommended if the social security is not paid much or not. When applying for outlets, you need to bring your ID card and proof of work income (work permit, employment certificate, tax bill for the last three months, social security bill, provident fund bill, etc.). Not all of them are required, but some of them are optional). If you can attach some financial certificates, such as the landlord can provide driving license, or real estate license, CCB deposits, it will be very helpful for the verification of cards and quotas. If the information is complete, it will generally be approved within 20 working days (almost one month) after the application.
