<p><font face="Verdana"><font face="Verdana">CHAPTER 1: iButtonTM OVERVIEW<br/>I. Introduction<br/>Although human–readable labels have been used for<br/>ages, it was the advent of computer–readable labels<br/>that quickly revolutionized the way grocery stores operate<br/>and made possible the overnight delivery of packages.<br/>When error–prone –– and time consuming –– key<br/>entry was replaced by bar codes, it became convenient<br/>to build large databases to help in making accurate and<br/>timely decisions.<br/>In the next step in the evolution of labelling technology,<br/>ink–on–paper bar codes are surpassed by silicon<br/>media. With Dallas Semiconductor’s automatic identification<br/>technology, a chip becomes the label that can<br/>serve as a standalone data base. Attached to an object<br/>or carried by a person, the chip identifies and carries<br/>relevant information available instantly with little or no<br/>human intervention. People access secure areas with<br/>convenience, health care professionals accurately<br/>create records, and workers efficiently track items as<br/>they travel along the assembly line.<br/></font></font></p>
