Abstract

[Ever since the advent of large-scale manufacturing, rapid identification techniques have been needed to speed the handling of goods and materials. Historically, printed labels, which are a simple cost-effective technology, have been the staple of the manufacturing industry. In the 1970s, labeling made a giant leap forward with the introduction of UPC barcodes [1] making it possible to both automate and standardize the identification process. Barcodes [2], although very inexpensive to produce, have many limitations: a clear line of sight is needed between the reader and the tag, they can be obscured by grease and nearby objects, are hard to read in sunlight or when printed on some substrates (Fig. 1.1). There are many types of barcode in use for specialty applications, including block-based optical codes. There are even miniture plastic barcodes called taggants [3] incorporated into explosives that are design to withstand an explosion and identify the supplier in case used for criminal purposes. However, for the scope of this article, barcodes labels and optical codes are considered as a single group. An alternative labeling technology is Radio Frequency Identification (RFID) [4–6], which enables identification at a distance without a line of sight. To provide some context Fig. 1.2 shows a variety of RFID tags designed for diverse applications in comparison to the size of a dime. Figure 1.3 shows a typical tag reader and remote antenna that can be installed in the area the tags are expected to pass through. It should be noted that as RFID is a radio technology, the tags do not need to be visible at all, and can be concealed behind an aesthetically designed label, or even molded into the product housing itself. For these reasons it is possible that many people may have encountered RFID tags but were unaware of them due to their invisible placement. Electronic tagging is superior to barcodes in many ways as it can reliably support a much larger set of unique IDs, and incorporate additional data, such as the manufacturer, and product serial number (Fig. 1.4). Furthermore, RFID systems can discern many different tags that are located in the same general area without human assistance. In contrast, consider the individual care needed at a supermarket checkout where each item is carefully orientated toward the reader before it can be scanned.]
