Mission

The mission of the RFID and Supply Chain Systems Lab is to advance the understanding of supply chain systems and how automatic identification of objects through RFID can be used to run supply chains in a more efficient manner.


 

What is RFID?

RFID stands for Radio-frequency identification. At its core, it is a contactless interrogation method for identification of objects. Besides  applications in supply chain operations, some of the everyday uses of this technology are in ID cards, sports equipment, windshield-mounted toll tags, and gasoline quick-purchase tokens. RFID has also begun to be used in keychain auto anti-theft devices and toys (most notably, Hasbro Star Wars figures), and even on paper tickets for the 2006 Soccer World Cup in Germany. An RFID system essentially consists of three parts: the RFID tag itself, the RFID reader device, and a backend IT system. The RFID tag typically consists of a silicon chip that can hold a certain amount of data (such as a unique identification number), and an antenna that is used to communicate with the remote reader device. There are chipless RFID tags as well, which exploit certain RF-reflecting properties of materials. In the case of chipless RFID, the tag’s unique serial number is given by the properties of the material, e.g. the configuration of RF fibers embedded in paper. The reader device communicates with the RFID tag by means of sending and receiving radio-frequency waves. The way this communication happens differs between so-called passive and active RFID tags. Passive RFID tags do not have a power supply; the energy stored in the reader device's radio-frequency interrogation scan is enough to wake up the RFID tag and to enable it to send a response (that is, the RFID tag's data) to the reader device by means of reflection. Active tags contain a battery that allows them to respond to the reader's interrogation with a stronger signal, thus increasing the distance from which the tag can be read. The backend IT system is responsible for cross-referencing the RFID tag's ID number with a database record that describes the object to which the tag is attached.

A recent paper (co-authored by Dr. Gaukler with Dr. Ralf Seifert at IMD Lausanne) gives an overview of current applications of RFID in supply chains. The paper is published as a book chapter in “Trends in Supply Chain Design and Management: Technologies and Methodologies”, edited by Hosang Jung, F. Frank Chen, and Bongju Jeong; Springer-Verlag London Ltd. You can download a copy of this paper here.
