The reason why the Guangfa card shows insufficient balance and can be used later.

1. GF has an over-limit function, which can be used later. After the total quota is used up, you can still exceed the quota by 10%.

2. The credit card limit has not been restored, or the remaining balance is lower than the expected credit limit.

3. The total limit of Guangfa Credit Card is 10,000 yuan. After the limit is used up, you can make an overdraft of 1,000 yuan. As long as the credit card bill is repaid in full and on time when it is due, no interest will be incurred. .
