1 .. There are few application materials.
The authenticity and integrity of the application materials is an important basis for the bank to approve the card. This information is especially important when applying for a credit card for the first time. For example, if you have a house and a car, you can submit a credit card limit such as a house purchase contract and a vehicle driving license. If you only approve simple materials such as a copy of your ID card, the probability is very small and the credit card limit is relatively low.
2. Bad credit report
After receiving the credit card application, the bank will check the applicant's credit record through the credit information platform. If you have a good credit record and the credit card limit is high, and now the limit is 0, it means that your credit may be problematic.
If you still don't understand, it is recommended to call the bank customer service, and there will usually be a professional explanation.
