Abstract: A device stores one or more compression rules for an action language. Upon receipt of a signal from a tag (such as an RFID tag, a visual tag, or an audio tag), a compressed data stream corresponding to the tag is decoded from the signal. Based on the one or more compression rules, one or more action parameters are derived from the compressed data stream. With these parameters, a corresponding action is performed. The action may include communicating across a wireless communications network as well as obtaining content from a remote content provider. Also the action may include storing data, such as a contact entry, or a calendar event.

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.
