Scan QR codes to unleash awesome.

QR codes are those black-and-white squares that hold information which when scanned can lead you to extra information or most likely on WeChat, to a cool action such as adding a friend, following an official account, linking to Web WeChat, entering a competition or even something more advanced. WeChat has a built-in QR Code feature that allows you to scan any QR code (so not just the ones created by WeChat).
