A methodology to read QR codes on uneven surfaces is developed

A team from the Micro and Nanotechnology and nanoscopies for Electronic and Electrophotonic Devices (MIND)- University of Barcelona and the Universitat Oberta de Catalunya has designed a methodology that facilitates the recognition of QR codes;  a mathematical solution to make it easier to read these two-dimensional codes on deformed surfaces. The new system does not depend absolutely on the underlying topography, and is applicable to QR codes that can be found on tubular surfaces (bottles), food trays, etc. It is the first technological proposal capable of combining a generalist methodology and two-dimensional barcodes to facilitate the recognition of digital information.
