1. If you have a family and have no job, you can apply for a credit card. As long as you apply to the bank with the real estate license, the applicant can get a high share if he has a house, and generally he can pass the examination and approval easily.
2. If you don't have a house or a job, you need to provide a credit certificate to the credit card bank you apply for. As long as you can prove that your credit rating is good, it is not impossible to apply for approval. To accumulate your own credit, you need to pay attention to accumulating your own credit in peacetime. Everyone must maintain rational consumption, repay in full and on time, and stay away from credit stains.
3. If you have no house or job, you can't prove your good credit. The last way is to deposit a certain amount of money in the relevant bank that applies for a credit card, and it will be approved soon. If the deposit amount is large enough, you can get a higher credit card.
