MIT’s Media Lab demos NewsFlash, Transmits data via high-frequency light to smartphones

MIT’s Media Lab is at it again. This time they demoed NewsFlash which uses high-frequency red and green light to transmit data to a built-in camera on a receiving device. In the demo they used an iPad to transmit to a Samsung Epic 4G. The concept is similar to a QR code, but no 2D square. Instead the generated lights are invisible to the human eye and a little more graceful. This is only at the concept stage so don’t expect to see this soon, but one has to wonder if NFC would be a better alternative. Hit the break for the demo video from Engadget.
