Credit cards can print transaction details, but only the issuing bank can print the transaction details of its own credit card. For example, if you have a CCB credit card, you need to go to a CCB branch to print the transaction details, but you cannot print it at other banks. At the same time, when printing the transaction details, the cardholder's ID card is also required. If printing by an agent, an authorized agent letter is required.

Credit card statement details cannot be used as materials for a loan to buy a house. A mortgage requires bank statements.
