A savings card cannot be upgraded to a credit card. Banks say this because the banking system has an automatic screen-popping system, which mainly identifies whether customers are qualified to apply for credit cards at CCB (no need to prove financial strength).

Generally, it is necessary to meet certain standards to apply for a credit card in CCB. If you are a civil servant, have you paid the provident fund, real estate license and land certificate, and have a private car for your own use, you can apply only if you meet the requirements.

CCB's automatic screen-popping system can identify customers with certain financial strength, and you can apply for a credit card with your ID card without showing the above proof conditions.

But the savings card is still a savings card, and the credit card and the savings card can be bound to sign a repayment contract.
