Radio frequency identification tags

It can be expected that, in the future, other organic electronic devices and circuits, such as sensors [72], radio-frequency identification tags (RFIDs) [73], and ring oscillators [74] may be fabricated using dissipative structures. 

A third important application for printed electronics is the Radio Frequency Identification tag, or RFID-tag in short. This tag, the follow-up of the barcode, is a transponder, consisting of a small chip and an antenna. The antenna is...

New technologies incorporated into products enable even more information to be leveraged by the supply chain. Radio frequency identification tags (RFID) represent one approach that could, theoretically, enable even a single unit of a product to be tracked. An RFID system transmits the identity (in the form of a unique serial number) of an object or person wirelessly, using radio waves ([2]). 

In June 2003, Walmart launched the start of a refailer compliance program stating that it would ask its top 100 suppliers to begin tagging pallets and cases with radio frequency identification tags (RFID). In... 

In addition to applications as functional materials in OLEDs and OSCs, semiconducting polymers are needed for other (opto)electronic devices as well. With regard to displays, sensors, and radio-frequency identification tags (RFIDs) for example, it is a challenge to create polymer-based organic transistors (thin-film transistors, OTFT field-effect transistors, OFETs). Figure 6.7 sketches an optional OFET design, and additionally shows schematically its principle of operation. 

Inventory control is generally in the form of log books or computer-based inventory systems. Chemicals are issued through written requests on prescribed forms, but there is no tracking of chemicals after they are issued to individual laboratories. No record of their use and disposal is kept. Bar codes and radio frequency identification tagging are available in some developing countries but are not commonly used for keeping track of where or how a chemical is used. Chemicals procured by individual faculty members with project funds are often not recorded in the central inventory faculty members are expected to add them to the central inventory voluntarily but have little incentive to do so. This is also true for laboratories in most developed countries. 

In 2005, Philips, which invests around 10% of its sales income on research and development, claimed a new research breakthrough with a polymer-based memory which is non-volatile, that is to say it will not lose data when the power supply is switched off. The technology involves the use of a field-effect transistor in which the gate dielectric is composed of a polymer ferro-electric material. Applications include the ability to make low-cost radio-frequency identification tags (RFID), a product which is being widely introduced into logistics and retail businesses with reported world production estimates of some 1.3 billion tags in 2005. 

For the following described model bar coding and bar code readers are essential in the retail supply chain. In the not too distant future bar coding will be replaced by RFID (radio frequency identification tags). The major difference is that RFID readers can recognize and record transactions without the goods...
