Abstract
The invention relates to a transponder for marking wood material and a method of manufacturing thereof. The method comprises embedding an RFID microchip and antenna into a casing essentially consisting of one or more biodegradable materials. According to the invention the embedding step comprises forming the antenna by layering conductive material directly on biodegradable material, and covering the antenna by biodegradable material. By means of the invention, environmentally friendly and pulping-compatible transponders can be manufactured, for example, for aiding the logistics of forest industry.
