Super modules-based active QR codes for smart trackability and IoT: a responsive-banknotes case study

Abstract The general use of smartphones assigns additional relevance to QR codes as a privileged tool to the Internet of Things (IoT). Crucial for QR codes is the evolution to IoT-connected smart tags with enhanced storage capacity and secure accesses. Using the concept of super-modules (s-modules)...
