1. If the credit card used by the user is blocked, the user can apply for a new card in the bank. Because although the credit card was blocked by the bank, the bank did not restrict users from applying for a credit card again.

2. However, it should be noted that users' credit cards are mostly blocked because of their own credit problems. If the user is indeed blocked because of bad behavior, then when applying for a new card in the future, the user will naturally not be approved to apply for a new card.

3. If the user's credit card is blocked only because the bank suspects that there is cashing operation, then the user will unblock the credit card for the user as long as he provides his recent consumption situation to prove that he has not cashed out. If users decide to apply for a new card, as long as they can prove that they have the ability to repay on time, they can generally apply for a card smoothly.
