There is no way to bring the sharer information to share a business card. you can consider some alternatives, such as using a temporary QR code with parameters:
When A shares, generate A temporary QR code with parameters, store the key and personal information of A in the form of A K-V, then A will send the QR code to B;
After scanning the QR code for follow-up, B will push A follow-up event to the server with the scanned QR code key. Based on this key, you can find the personal information of the QR code Sharer.

The official name of key is the scene value ID: scene_str
