BlueRay
"San Francisco's WideRay has placed kiosks in selected music stores, video game stores and theaters across the country and in Europe. When customers come within 25 feet of the kiosks, they receive an SMS asking if they're interested in getting more information about various items the store is selling, perhaps music, ring tones, videos or games. If customers are interested, they can go to the kiosk and choose what to download.
The messages and downloads reach customers' cell phones over radio waves using Bluetooth. ... Customers can choose between free downloads and those that come with a fee. But no additional charges appear on customers' cell phone bills because the transaction doesn't involve the wireless carrier.
