Why did the newly established ETC fail to pass the certification?

Have you contacted the customer service of Guangfa Bank? You may receive a scam message, don't try to understand the link it gives. Previously, GDB's ETC credit card "application and use" card service did not have the so-called invalidation problem, and it was permanently valid after activation. Unless your card expires or is reset due to loss reporting, ETC equipment will be stopped from paying, but you can use it again as long as you change the card through an ETC partner and enter the new card information. Neither banks nor ETC partners send short messages containing links to ETC users.

Note: Anything that requires you to hand over the withdrawal password, security code, dynamic verification code, etc. It's fraud, so we must ignore it.
