QR codes, or quick response codes, are square bar code designs that can be used to direct users to a webpage, video, document, or phone function. Users access the content by scanning the code with their smartphone or tablet camera.
To use a QR code, customers simply point their phone camera at the code and the webpage or phone function will open automatically. Some phones may require a QR code reader app, which can be downloaded for free from an app store.
Invite people to follow you on social media, then provide a code to link to your profile.
