1, prepare in advance.

Contact the bank one month before the credit card expires and ask for a new card, otherwise it will not be used once it expires.

2. Activate the new card.

When the credit card expires, the old card can still be used after the card is successfully processed, and the old card will be invalid after the credit card expires or the new card is activated. Therefore, once the new card is available, it must be activated in time.

3. Old cards should be cut and destroyed in time.

Old cards may still be stolen. To be on the safe side, the old card should be cut and destroyed in time after the new card is activated. However, many players are collectors. If you can't bear to cut the card, remember to keep it.
