TRANSFERRING DATA VIA AUDIO LINK
First Claim
1. A method of transmitting a data item to a mobile communications device comprising;
- receiving a data item for transmission at a processor;
transmitting the data item to a remote device;
receiving from the remote device a data token which is associated with the data item;
encoding the data token as an audio sequence; and
playing the audio sequence through loudspeaker for capture by a microphone at the mobile communications device.

Abstract
Transferring data via audio link is described. In an example a short sequence of data can be transferred between two devices by encoding the sequence of data as an audio sequence. For example, the audio sequence may be a sequence of tones which vary in dependence on the encoded data. The sequence of data may be encoded by a first device and transmitted using a loudspeaker associated with the first device. At least one mobile communications device can be used to capture the audio sequence, for example using a microphone, and to decode the sequence, retrieving the data encoded therein. In some examples the encoded data may comprise a shortened URL or other information which can be used to control one or more aspects of the capture device.
