What was the error prompt at that time? There are many reasons why the card can't be used, such as is the card damaged? Is the available quota sufficient? Whether the card status is normal, and so on. If the landlord's credit card supports VISA, MasterCard and UnionPay, it can be used overseas. It doesn't matter if this card only has the VISA logo, as long as it can be used by overseas merchants who support VISA, so the key depends on whether there is any problem with the status of this card. The landlord can call the customer service hotline of CCB first to check.
