What is M-Tag® ?

M-Tag® is a security solution that provides off-line and online authentication using a magnetically color changeable special high-security material and mobile phone application ‘M-Check’ respectively.
The authenticity product can be verified by checking a color change of the label using magnets (e.g. rubber magnets, speaker magnets of mobile phones or laptops) that is readily available in everyday life. In addition, its high-security features are optimized to prevent counterfeit goods from various products.
NANOBRICK’s magnetically color-tunable photonic crystal (MTX) is a new innovative material that changes color depending on the external magnetic field which affects an internal structure change of material.

The sources of mysterious colors including morpho butterfly, chameleon and opal jewelry resides in the regular arrangement of nanoparticles

NANOBRICK’s magnetically color-tunable photonic crystal (MTX) is a new innovative material whose color changes depending on the external magnetic field through stimulation technology
(Mimix) to implement the mysterious colors of nature.
