The identification label for touch panel sensing described in item 2 of the scope of patent application further includes a back adhesive layer formed on the second surface of the substrate. For the identification label for touch panel sensing described in item 2 of the scope of patent application, each of the sensing areas has an area of at least 0.5 square centimeters. The identification tag for touch panel sensing as described in item 2 of the scope of patent application, wherein the impedance of the first identification layer is not greater than a square resistance value of 1000 ohm/sq. The identification tag for touch panel sensing as described in item 2 of the scope of patent application, wherein the impedance of the first identification layer is not greater than 100 ohm/sq square resistance. The identification label for touch panel sensing as described in item 2 of the scope of patent application, wherein the substrate and the first identification layer are transparent.
