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) built from adjacent spatial multiplexed modules with regular geometrical shapes, assisted by colour multiplexing, we modelled and design a single QR code with, at least, the triple storage capacity of an analogous size black/white QR code, acting as a smart-tag ensuring restrict access and trackability. The s-modules are printed using luminescent low-cost and eco-friendly inks based on organic-inorganic hybrids modified by lanthanides with multiplexed colour emission in the orthogonal RGB space. The access to the restrict information is attained only under UV irradiation and encrypted for secure transmission. The concept of active QR codes for smart trackability and IoT was materialised through the development of a free friendly-user mobile app.

智能手机的普遍使用为QR码分配了更多相关性，作为物联网（IoT）的特权工具。QR代码至关重要的一点是向具有连接物联网的智能标签的发展，该标签具有增强的存储容量和安全的访问权限。使用由具有规则几何形状的相邻空间多路复用模块构建的超级模块（s -modules）的概念，并借助颜色多路复用，我们对单个QR码进行建模和设计，至少具有类似黑色大小的三倍存储容量/ white QR码，用作智能标记，可确保限制访问和可跟踪性。在小号组件使用基于镧系元素修饰的有机-无机杂化体的发光低成本环保型油墨进行印刷，并在正交RGB空间中进行多重颜色发射。仅在紫外线照射下才能访问限制信息，并进行加密以确保安全传输。通过开发免费的友好用户移动应用程序，实现了用于智能可追踪性和物联网的主动QR代码的概念。
