Abstract
Source data stored on a source device may be shared with one or more devices. Sharing the source data may include facilitating obtaining an image of a visual tag from another device. A visual tag may be obtained via a communication method or optically captured via an optical device. The visual tag may comprise a visually encoded first token associated with the source data. The first token may be a non-public token based on the source data. The visual tag may be decoded to retrieve the first token. The device with the retrieved first token may provide for communication based on a communication protocol to a second device to download the source data using the retrieved first token. A device may be adapted to provide display of the visual tag or communicate or receive the visual tag.
