LONDON: A British team has developed 3D barcodes that could differentiate counterfeiting of drugs, watches and other products.
The codes consist of a series of small indentations with precise, slightly different depths, allowing for billions of different combinations.
They are deciphered by a device that “reads” the dents using beams of light. The system was developed by Sofmat, a small Yorkshire company, in collaboration with engineers at the University of Bradford.
