Axel Kupisiewicz , founder of Trackinside, makes the laser that can write on the inside of glass. This laser technology allows to make markings inside transparent materials without damaging them in any way. There are no fissures, no cracks, nothing. And have to say that he aren’t using any additives, like ink, so there are no consumables, he use nothing but laser to put the hologram inside the glass .The laser system can etch a unique code below the surface of glass containers, at a rate of 10 engravings per second. A camera captures the code and puts it on screen, allowing the system to decode the information contained in the data matrix.
