LiFi uses light to send and receive data
A company at CES, Oledcomm, displayed its LiFi method of transmitting data via light. A plain Android handset was modified by replacing the front-facing camera with a light sensor, and pulsating streams of light were used for the transmission of information. To the naked eye, these appear as a steady stream of light. Besides outfitting a smartphone in this manner, a tablet also had its front-facing snapper replaced. Both devices require a special LiFi dongle, which is plugged into the earphone jack.

After installing a special app on the phone and tablet, holding either device near lamplight set off a number of events, including the displaying of certain pictures, the playing of a video or the booting up of specific games. Oledcomm believes that its LiFi technology can be also used for location based advertising, similar to what Apple is doing with the iBeacon in its retail stores.

First things first, Oledcomm needs to convince smartphone manufacturers to include its light sensors on their brand new smartphones rolling out of the factory. You can see the technology on a concept phone, and the dongle necessary, by clicking on the slideshow below.

This is a pretty cool technology and would be really convient to have like in a super market to get quick details about a product...but in order to do this they are going to have to partner with some of the big dogs like lets say Samsung and Walmart then hopefully it will catch on

That is why we have barcode scanners.

Apparently it's just a more glorified version of NFC. Would be cool though if this technology can evolve to be the next WiFi

Seems pretty limited.if you turn your smartphone away from the source and are not in direct line then would you not lose the stream?also would not be able penetrate walls like wifi.

If every light in the store was emitting the same information, it would be difficult to turn away from it.

And if it's intended for location-based advertising, all the data it ever needs to push to your phone could be completed in fractions of a second.

How about making a pistol/rifle attachment for the phone that connect to the earphone jack and has a mount for the phone on top so the user can see information? The light sensor could be on the front of the pistol/rifle and so could the light transmitter. You could make a custom app to send and receive information long distances or even to play laser tag with your smartphone. You know you want to steal this idea. Just put this comment in a sourcelink on your web page for it, please.

LOL. Laser Tag died. Nobody will pay a fortune to get it back in an advanced-technology form.
