1. Suspected of cashing out:
If the cardholder withdraws a large amount of cash, or swipes his card many times in a merchant who is suspected of cashing out, it will be recognized by the wind control system as a cash-out credit line, thus reducing the amount.
2. It may be a stolen brush:
If the credit card is likely to be stolen, the bank will reduce the credit card limit.
3. Don't use it for a long time:
The frequency and amount of credit card consumption are relatively small, and the bank will decide that the cardholder does not need such a high amount, thus reducing the amount.
4. Credit card overdue:
If you don't pay it back within the time limit, the bank will reduce your credit card limit in order to stop the loss.
