Investigators of the United States have designed a device that can become an alternative to bar codes. It is called “Bokodes”, and it can store thousands of times more information than the traditional lines and they can be read by a camera or a mobile phone.
With only three millimeters in diameter, these tags, might contain codified information about nutrition, food expiration or even serve to create new video games.
The work will be presented in a conference in New Orleans next week.
The “Bokodes” consists of a LED ( light emitting diode), covered with a minuscule layer and a lens. The information is codified thanks to the light that shines across the layer, which changes its intensity depending on the angle from which it is seen.
They can be used in industries not to lose of sight objects, but also they can be used in supermarkets. Also it would be useful in libraries to locate a book with ease among thousands or to find information about restaurants.
These “Bokodes” are expensive, 3.5 euros a piece as of now though.
