What does it mean to enter an additional code when purchasing wealth management products?

Additional code, also called verification code, is to generate a picture from a series of randomly generated numbers or symbols, and add some disturbing pixels to the picture, so that users can intuitively identify the verification code information in the picture, enter the form and submit it to the website for verification, and then use a function after the verification is successful. The verification code is generally used to prevent people from being automatically registered in batches by robots, and constantly log in to specific registered users through violent cracking of specific programs.
