For specific usage, it is suggested that the landlord can go to official website-Account Inquiry Service on the left side of China Construction Bank, select "Credit Card Inquiry", and check the detailed usage of the card after entering the information as required. The specific method is as follows:

In addition, there are several situations that may lead to the line being occupied.

First, the existence of the card is not accounted for, but only caused by the transaction in the authorization stage (the transaction was successful, the bank frozen the quota, and the merchant did not ask the bank for money). (In this case, it is suggested that the landlord check in the unpaid bill two days later, because domestic transactions are recorded in 1-2 days. )

Second, is there any pre-authorization for card release? Generally, staying in a hotel and renting a car will involve pre-authorization, just like a deposit. When leaving the hotel or returning the car, the merchant will use this pre-authorization to settle the bill, and the refund will be less, so that the pre-authorization is completed. However, in some cases, payment was made by cash or other cards at the time of settlement, and the original pre-authorization was not revoked by the merchant staff, resulting in the quota being occupied. In this case, the domestic pre-authorization will be automatically lifted within 30 days, and the quota will be restored, so the landlord need not worry.

Third, the landlord made installment payment, and the unpaid installment amount occupied the credit card limit, but it was not shown in the balance because it was not officially recorded.

If the landlord has other questions, you can ask.
