Abstract
An RFID tag for marking storm drains incorporates the tag circuitry into a dome decal providing a flexible substrate capped by a self-leveling clear polymer. The RFID tag is placed between the polymer and the substrate on an electromagnetic radiation decoupling layer allowing a low profile fitting within the decal while allowing the decal to be used on metal drain surfaces. The decal includes a printed environment-promoting message relating to connection of the storm.
