If you are not at home and can change your card on 5 March, you can use your old card until 4 March. Then, on March 5, you can add your new card to your digital wallet. You do this directly in the FOREX Credit Card app by clicking on your card and then "Digital wallet". You will also find your card details in the app, and can thus use your new card also for online purchases where Apple Pay or Google Pay are not accepted.
