Abstract
Embodiments of the present invention provide a method and system for embedding, transmitting and receiving a Quick Response (QR) code in an audio file. Initially, a set of data representing a QR Code and an audio file is received. A third file is generated based on a combination of the QR code and the audio file. The third file is broadcasted and received by a device. Data representing the QR code is extracted from the third file and displayed as an object on the device.
