Abstract: A capacitive sensing identification tag includes a substrate and a touch sensing layer disposed on one side of the substrate. The touch sensing layer includes high-sensing regions and low-sensing regions with different shapes. Both the high-sensing regions and the low-sensing regions have different stacked conductive layers and dielectric layers.

And the capacitive sensing identification tag will not cause a difference in color or light transmittance between the high-sensing regions and the low-sensing regions, so there is no visible difference between the high-sensing regions and the low-sensing regions.
