Fujitsu Black Technology: Light becomes two-dimensional code on things

We all know that if you want to know more about something, find its two-dimensional code and sweep it. But the problem, two-dimensional code after all look bad, how to do? Just use a beam of light. Fujitsu, Japan, has unveiled a very interesting new technology that uses LED lights instead of two-dimensional codes. As long as the LED lights hit an object, and then we use the phone to sweep it, the relevant information appears. How do you do that? Originally Fujitsu used not ordinary LED lights, but red and blue fast flashing special type. The red light represents 0 of the binary, and the blue light represents 1, which repeats itself. Because it flashes fast, the human eye is not able to see the difference, but the mobile phone through a special application can read this code. While there are other similar technologies, such as GPS and Bluetooth, Fujitsu says the technology is too broad and blurry to project directly onto an object like the LED two-dimensional code. If new technologies are applied, future shopping malls will become more beautiful. Any product, as long as a beam of such light projected on it, we can quickly get the information we want.
