This booklet presents an creation to RFID know-how. It describes and addresses the next: How RFID works, the way it is and will be utilized in present and destiny functions. The historical past of RFID expertise, the present country of perform and the place RFID is predicted to be taken sooner or later. The position of middleware software program to path information among the RFID community and the knowledge know-how structures inside of a company. advertisement and executive use of RFID know-how with an emphasis on a variety of functions together with retail and customer packaging, transportation and distribution of goods, commercial and production operations, safety and entry keep an eye on. criteria and the regulatory compliance atmosphere and at last, the privateness concerns confronted through the general public and in regards to the deployment of RFID expertise.

Example text
In contrast, smart labels and RFID in general uses radio waves to carry information. Bar coding is therefore referred to as an optical technology and RFID is called a radio frequency or RF technology. This has several implications for AIDC. Below is a detailed comparison of RFID to bar codes. 1 Memory Size/Data Storage Bar codes can only hold a limited amount of data. The smallest tags, in terms of data storage, are UPC E symbols, which hold only eight numeric characters; just a few bytes. At the opposite end of the spectrum, the Data Matrix bar code standard permits the storage of 2000 ASCII characters, on a twodimensional tag, as shown in Figure 2-9, though these are rarely used.
Early movers are the companies or industries that are leading their industry in terms of RFID adoption and are able to drive major RFID programs that influence their particular industry. They are able to gain the greatest knowledge, have the ability to influence standards, are ready to make significant investments, and take risks. Fast followers are companies or industries that hesitate to invest in the technology, but aim to gain knowledge and target specific areas at points in time where the cost/benefit can be justified.
There are several that now offer smart label printer solutions, which both print out adhesive smart label tags and write data to tag memory. There are even some hybrid bar code/ smart tag solutions that both print a UPC bar code symbol on an adhesive smart tag and write data to tag memory simultaneously, in order to assist customers in migrating between the technologies. There are many measures by which RFID smart labels do not yet stack up to bar codes, such as price, technological maturity, and ease of implementation.
