QR codes in microscopic sizes will help stop counterfeiting

invisible qr codes

A lab in Toulouse, France, have discovered a way to make a quick response code half a hair’s diameter. A company called Nanotech, out of Toulouse, France, has now revealed that they have developed QR codes that are invisible to the naked eye, but that can still be scanned and used for a number of purposes, primarily in the form of security. These micro tags use nano particles and are so small that 10,000 can be printed in one square centimeter. The Nanotech team was led by Laurence Ressier, have…
