Title: Understanding Chipless RFID: From the Radar Principle to Scalable Identification
Speaker: M.Eng. Ines Bakri, Research Associate and Doctoral Candidate at RheinMain University of Applied Sciences and Arts
Date: June 17, 2026
Language: English
How can products, packaging or assets be identified without a silicon chip?
In this lecture, Ines Bakri of RheinMain University of Applied Sciences introduces the fundamentals of chipless RFID and explains why electromagnetic signatures could open new possibilities for scalable, passive and printable identification.
The session compares chipless RFID with established RFID, barcode and optical identification technologies, starting with the underlying radar principle: instead of storing data on an integrated circuit, the tag reflects a characteristic electromagnetic response that can be detected and interpreted by a reader.
The lecture also gives a realistic view of the current state of research. While chipless RFID could support low-cost and high-volume applications in logistics, retail, smart packaging and sensing, major technical challenges remain. These include limited data density, interference and noise in real environments, multipath effects, reader sensitivity and the lack of common standards.
Watch the recording to learn how researchers are addressing these limitations through calibration techniques, improved signal processing and MIMO-based detection approaches, and where chipless RFID may become a practical complement to barcode and conventional RFID systems.
Chipless RFID technology enables scalable and cost-effective identification through electromagnetic signatures, offering a promising alternative to silicon chip-based methods despite current technical challenges.
