A team of researchers at the University of Montpellier in France have developed a way to embed a thin aluminum RFID tag on to paper.
Using a process of thermal evaporation the team was able to deposit an aluminum coil antenna on to paper for use as an RFID tag, which could potentially open up RFID tagging to many applications, allowing even a single printed sheet or flyer to be tagged.
Prototypes are said to be functional and easily detected by the reader. The next step is optimizing the design for each family of RFID chips – improving performance while maintaining the same low-cost technology.
Aluminum is a less expensive than copper and silver, which are commonly used in some types of RFID tags. Adding to this, the researchers said the newly developed method uses less metal which further reduces the cost of production.
