A user of a social networking system performs an action with a device associated with a terminal, and based on the action, the terminal displays a visual representation of machine-readable code (e.g., a QR code) that encodes information about the action or a link to a source for obtaining such information. The user captures the machine-readable code with a mobile device, and an application on the device obtains the information describing the action from the machine-readable, associates the information with the user's identifier and communicates the information and user identifier to the social networking system. Using the information describing the action, the social networking system may then publish an action, add to the user's user profile, and/or perform other tasks based on the received information. |
