Generally speaking, credit cards are valid for two years. Of course, some credit cards are valid for a long time, but it depends on how the landlord's credit card is stipulated. The landlord can set the validity period of the credit card on the number below the card number. Assuming that the number below the building owner's card number indicates 08/222, then the building owner's credit card can be used in August 2022, because the validity period of the credit card is month/year, which requires the building owner.
