In article number 1801070 , Junsuk Rho and co‐workers realize polarization‐encrypted nanoprints by tunable structural coloring with a combination of symmetric and asymmetric nanoantennas. The polarization‐encrypted nanoprints designed based on Kerker's condition are decrypted under a certain polarization angle of incident light. The demonstration of the nanoprints expands the scope of metasurfaces toward novel security technologies, and thus further shows their potential for integration with smartphone applications or a variety of Internet‐of‐Things technologies.
