Hello, you asked if it is okay to leave one yuan in the credit card on purpose, that is, if you don't cancel it? It is impossible to leave a dollar on a credit card without paying it back, that is, without canceling it. Interest and penalty will be incurred after the credit card is overdue. If it is deliberately not returned, the bank will collect it and even sue the cardholder. Moreover, overdue credit card records will affect personal credit records and have a negative impact on the credit rating of cardholders. Cardholders don't want to cancel their cards, so they should repay them in time and keep a good credit record. In case of financial difficulties or other circumstances, you can negotiate with the bank to make a repayment plan to avoid overdue and extra expenses. Therefore, it is wrong to deliberately not return the credit card with one yuan left.
