Do I need to rebind WeChat to change my credit card?
Whether to rebind WeChat when changing a credit card mainly depends on whether the card number has not changed after changing the card, but the new card number will be different when changing the card due, losing the card and upgrading the card, as follows:
1. Credit card replacement upon expiration: the new card number is the same as the original card number, but the validity period and security code have changed, so it is unnecessary to rebind WeChat.
2. Replacement card for loss reporting of credit card: Although the obtained new card carries the accounting information of the old card, the card number and security code are different from the old card except that the pinyin of the cardholder's name on the card number remains unchanged, so it is necessary to re-bind WeChat.
3. Credit card upgrade and card replacement: the level of the new card obtained is higher than the old card, and the card number will be different from the old card. We also need to rebind WeChat.
Can I still use my old card after changing my credit card?
If the new card is not activated after receiving it, the old card can continue to be used until the expiration date, but it cannot be used after the expiration date. If you activate the new card immediately after receiving it, the old card cannot be activated and used at the same time as the new card, even if it has not yet reached its expiration date. In short, the old card can be used within the validity period without activating the new card. Once the new card is activated, the old card cannot be used immediately.
