An identification appliance, such as a wristband, bracelet, patch, headband, necklace, card, sticker, or other wearable appliance, has an improved patch or microstrip antenna. An exemplary cartridge assembly comprises a cylindrical inner surface for holding medicament and a cylindrical outer surface comprising a fastening feature having a first coding element protruding from the cylindrical outer surface. The device can be used as a construction material to efficiently regulate the internal temperature and illumination of buildings, vehicles, and other structures without the need for an external power supply or operator signals. The applicator is preferably removed directly after application of the oral composition.
