Abstract
The invention is defined by systems, methods and applications for establishing a short-range communication link between digital devices for the purpose of transferring data between the devices. The first device generates and displays a visual code that encodes the address of the first device and the location of data element desired to be transferred. A second device, which implements image capture capability, captures the visual code and decodes such to determine the address of the first device and the location of the data element. Upon decoding, the second device will automatically initiate the short-range communication link between the first and second digital devices and the transfer of the data element from the first device to the second device will ensue.
