If you want to continue to use it, you need to rebind the bank card. You only need to open the App of your futures company and click on the relevant content of the silver period to complete the unbinding and replacement.
Generally speaking, the bank card exchange only supports the unbinding service from 9: 00 a.m. to 9: 00 p.m. 15 on the trading day, and unbinding is not allowed at other times due to bank audit and other issues, which you need to pay attention to.
