Why does Agricultural Bank of China always show the error of verification code in the commemorative coin reservation?

In the case of ensuring the accuracy of the verification code input, prompting that the verification code is wrong may be one of the following two reasons:

1, page refresh problem

The login verification code will change every time the page is refreshed. If you are prompted that the verification code is wrong, the system will replace the verification code. At this point, the page may still be the previous verification code. Re-enter a new verification code after seeing that the verification code has been replaced.

2. Full-angle/half-angle problem of input method.

Operating environment: MacBook, macOS( 10. 15.7) system, Google browser, official website, China agricultural bank. The number of full angle/half angle inputs in the input method is different, that is, the number of full angles 1234 and the number of half angles 1234 are different. Although the figures are correct, they still cannot be verified.
