A client device detects a QR code (or NFC tag). The client device decodes the QR code. The client device determines that the data encoded within the QR code includes a URL. Based on the URL, the client device sends a first request to a first server identified by the URL. In response to the first request, the client device receives from the first server data configured to cause the client device to display, to a user of the client device, at least one of: a video or an interactive web page. Responsive to the data encoded in the QR code, the client device sends to a coupon server: identification data associated with a user of the client device, and a request for the coupon server to distribute a digital coupon for an offer associated with an identifier encoded within the QR code to an account associated with the user.
