What are the requirements for upgrading a second-class card to a first-class card?

To upgrade a first-class card to a bank card, you need to meet the following conditions:

1. This bank does not have a first-class card: this is a prerequisite for upgrading. Only when there is no first-class card can the second-class card be upgraded.

2. Cardholders need to provide identity documents and bank cards: this is a necessary condition for upgrading, and banks need to check the identity information and bank card information of cardholders when handling upgrading business.

3. The second-class card needs to be within the validity period: if the second-class card has expired, it cannot be upgraded.

4. The status of the second-class card needs to be normal: if the status of the second-class card is abnormal, such as arrears, it cannot be upgraded.
