Is it illegal for Tik Tok to send and receive bar codes for money?

Generally speaking, it can be sent, but if you don't cooperate, you will be restricted or deleted by the platform.

Tik Tok is essentially a 15 second music short video community focusing on young people. Users can choose songs and mix them with short videos to form their own works. Similar to the small card show, but the difference is that Tik Tok users can make the video more creative through video shooting speed, video editing and special effects (repetition, flashing and slow motion), rather than simply lip-synching.
