Why does mobile banking need a form verification code to enter the wrong password?

There may be the following reasons why you need a graphic verification code when you enter an incorrect password in mobile banking:

Improve account security. Automatic public turing test (CAPTCHA), commonly known as verification code, is a fully automatic program to distinguish whether a user is a computer or a human.

In case someone enters it indiscriminately, it will destroy the stability of the account. Verification is accomplished by recognizing graphics, which are the combination of irregular graphics and text. It is used when users log in or register, but now it is usually used in combination with verification code messages to achieve a higher level of network security.

Stop the virus from invading. In order to prevent automatic program login, many Trojans log in like that, so in order to prevent Trojans, a verification code is made, which is inseparable from Trojans. Sometimes it is suspected to be a Trojan horse because of too many operations, so it will pop up for verification.

If consumers can't input the graphic verification code independently, they can go to the local mobile banking outlets with their bank cards and ID cards to handle related business.
