  • Multiplexed luminescent QR codes for smart labelling, for measuring physical parameters and real-time traceability and authentication
    Patent number: 11803722
    Abstract: The present technology discloses smart labels to monitor physical parameters, and for traceability and authentication of objects, documents or people. This active and multifunctional label is based on spectrally and spatially multiplexed Quick Response (QR) codes (A). Spectrally selectivity is achieved using luminescent materials and spatially multiplexing is achieved using different patterns (B) combining both to design improved QR codes able to store information at different layers of accessibility. This brings advantages over the actual scenario of QR codes wherein the amount of storage information increases up to three times, adding the capability to sense physical parameters and allow to control the provided information, creating public and restricted access. To access and read the content of each layer, different illumination is used (C) to (E) and is processed using a device or via dedicated applications.
