What is the business card of YunCambodia?

YunCambodia business card is a sales tool, which adds a small program to the traditional paper business card, and has the mode of management, social interaction and official website plus shopping mall.

I made a rough count on the Internet and found that there are dozens of artificial intelligence business cards with functions such as company name, address, name, department, position and contact information. On the basis of paper business cards, artificial intelligence business cards can directly extract and retrieve the information in business cards by using image recognition technology.
