Abstract: A short-range radio transmitter establishes a link to a portable digital device (user device) within the transmitters range and transmits a universal resource locator (URL) to the device. As the user device receives the transmission, software is launched, and the software requests information from the transmitted URL via a different radio frequency link. The present invention allows individuals and businesses to install short-range radio transmitters in specific locations and cause a user device within a definable range to automatically display relevant information associated with that location. The information includes advertising, product, equipment, inventory, online payment processing, and information relating to any additional field.
