Casio Camera App Uses Light To Send Secret Messages

The camera in your smartphone is good for a lot of things, and we’re not just talking about Instagram and causing the sad yet inevitable demise of the point-and-shoot; now it can also be used to send and receive secret messages using light. A new Casio camera app called Picapicamera encodes messages or graphics using a sequence of red, green and yellow flashing lights, which another user of the app can then point their camera at to decode.

For now the app is limited to the amount of data of an 8-bit word (which can potentially be a link to more text) but in the future Casio hopes that this sort of tech may take the place of, or join forces with, QR codes to make for more immersive, camera driven advertisements. Check out the video above for more details, or if you wanna pick up the app for yourself, it’s already available for free on the iTunes app store.
