Can a Mongolian businessman's credit card be used after it has expired?

Under normal circumstances, credit cards cannot be used when they expire.

When your credit card expires, you need to replace it to continue using it. Many banks will send text messages before the debit card expires, informing cardholders to change their cards at bank outlets in time. Cardholders only need to bring their valid identity documents and debit cards to the bank outlets for card replacement. Banks will generally issue new cards to credit card users before their credit cards expire, and cardholders can use the new cards directly.
