Why can't China UnionPay Express pass be verified every time?

1 There may be something wrong with the operation of the mobile phone or computer. You can try restarting your phone or computer. Perhaps there is not enough memory to receive new information, and the software can clean up the garbage and release the memory. Maybe the downloaded software is damaged. You can uninstall the original software and then download and install it again. Maybe the date and time on the mobile phone or computer are wrong. You can check whether the date and time are correct. If the date and time are incorrect, it will cause a network error. It is also possible that there is something wrong with the software server and it will take some time to recover.

Under normal circumstances, China UnionPay Express will not use slide chart verification. You just need to click "Open" to use it. However, if you need to use China UnionPay Express after cancellation, you need to log in again. If your login password is entered correctly, you can also use China UnionPay Express. However, if the login password entered is incorrect and the password needs to be retrieved, there will be a slide show to verify it. Of course, it is not difficult to verify the slide chart, just press and hold the slide chart with your finger and move it to the normal position.
