No, once you apply for a replacement card, your old card will be invalid immediately after the customer service confirms it with you. New cards are usually made within 3 working days, sent by registered mail, and generally received within 10 days. After receiving the new card, you can use it. The password of the new card is the same as that of the old card. PS: The card exchange fee in 20 yuan will be deducted from the credit card.
