The technology is based on the company's research into the developing field of "Li-Fi," or sending information using visible light. Using LED lights, data can be encoded into slight fluctuations in brightness that are invisible to the naked eye, but can be read by dedicated receivers.
With specialized equipment, this can achieve data transfers at hundreds of megabits per second, but Casio wants to use the technology for existing consumer devices. In many cases, the data encoded and sent by the flashing beacon will probably be a short look-up code or URL, which is then used to pull a larger data file from a server.
