The main reasons why the credit card shows that the loss has been reported are as follows:

First, when cardholders swipe their cards, there are many large and integer purchases. In order to ensure the safety of credit cards and funds, the banking system will take the initiative to temporarily freeze credit cards.

Second, when the cardholder's credit card is frozen, it will trigger the bank's 24-hour temporary freezing function, and the banking system will automatically report the loss of the credit card.

Third, when the cardholder makes a transaction in a risky merchant and the transaction amount is large, the banking system may also temporarily report the loss of the credit card.
