If you want to apply for a China Merchants Bank credit card or a gold card with a relatively large credit limit, or a card above the gold level, in addition to your ID card and work certificate, it is recommended to provide more financial information. It can be salary records issued by the bank, or income tax withholding vouchers, or documents proving the market value of houses, cars, deposits and investments (such as copies of real estate certificates/car driving licenses/bank time deposit certificates) and other documents that can prove your financial level. Other documents available for reference include: social security personal account list in the past six months, water and gas bills, credit card bills from other banks, etc. The main ones are your large deposit slips, real estate certificates, and copies of driving licenses for high-end private cars. If you can provide relatively complete financial documentation, it will be more helpful for us to understand your personal situation and determine your credit limit. If the local branch has clear regulations, the regulations of the local branch shall prevail. The issuance of the credit card shall be subject to the final review result.
