When does China Bank need to enter the verification code when scanning the code?

After entering the mobile phone number.

According to the official data of Bank of China, the mobile phone terminal is not a strong device authentication terminal. The so-called strong device authentication terminal refers to logging in by user name and password, and needs to be verified after entering the mobile phone number. The verification method is to obtain the verification code and enter the verification code.

The verification code is a public automatic program, which is used to distinguish whether the user is a computer or a person.
