With the use of QR codes, Chinese business owners have effectively replaced the use of business cards; however, QR codes are also used to connect friends who want to connect on WeChat. There are capabilities for conference calling on WeChat, which makes working while on the app a very common scenario in Chinese workplaces. In addition, enterprise accounts are specifically designed to make jobs easier by allowing users to apply for leave, tracking projects, and so forth. In conferences, users can use the Notes feature and share with others. With these valuable built-in business tools, WeChat crosses over from being simply a method to contact loved ones, but rather to one that can help businesses grow and prosper.
