WeChat automatically creates a QR code for each WeChat official account, and the app itself has a built-in QR code scanner. You can also customize the QR codes to match your branding. These codes can be posted in all of your marketing channels, such as on other social media networks (not Weibo you might get penalized), product packaging, brochures, or even in your brick-and-mortar stores.
QR codes are a great way to entice customers as they allow you to offer discounts, promotions or free WiFi access. With just a simple scan, you can boost both sales and followers on your WeChat official account.
