Systems, apparatuses and methods of using an acoustic communication mechanism to transmit data in the form of acoustic data from a mobile device to an electronic device are described. In one embodiment, a method of completing a purchase with a merchant using a mobile device starts with the mobile device sending a request message to a central server through a network interface. The mobile device then receives a token from the central server through the network interface that confirms that a payment in the purchase amount has been received at the merchant's account. This token is then translated into acoustic data and transmitted from the mobile device to an electronic device being associated with the identification of a merchant. Other embodiments are also described. |
