Recently, the Fraunhofer Institute in Germany, the largest applied research institute in Europe, has developed a wooden label for tracking wood, according to Discovery News.
The label is cheap and consists of paper and a chemical compound lignin extracted mainly from wood. The tag is connected to an antenna. When the truck passes through the entrance of the RFID reader, the tag is read. The tag stores a digital code that corresponds to relevant information such as the source, quantity, type, and destination of the wood.
According to the agency, the metal content in the new label is much smaller than the amount of wood around the wood.
