What Is It? • Radio Frequency Identification, or RFID, is a tag that can be attached to merchandise or other objects. They are read using an RFID transceiver for the purpose of identification.
RFID tags consist of an antenna and a chip. The antenna transmits the identification to the reader. The reader then translates it into digital information that is passed on to a computer. How It Works
RFID tags usually range from the size of a postage stamp to the size of a pager; some can be as small as a period. Currently, the cost per tag is about 30 cents apiece; It is expected to drop to as little as three cents in the next three years. Retailers will still have to purchase sensors to read the tags, which can cost $1,000 each. Tags can be read from a distance and through a variety of substances such as snow, fog, ice, or paint. Information
Regardless of cost, thousands of companies are using RFID tags. Here are some examples of the companies: • Wal-Mart • Target • Johnson & Johnson • Nestle • Pepsi • Coca-Cola • Hospitals • Airlines Where Is It Used?
How they are being used • Hospitals put the tags on a patient’s wristband. It keeps track of newborns. • To keep track of luggageand stolen cars; They are also injected under the skin to track lost pets, ex-convicts, and employees in high-security facilities. • The ScriptTalk prescription reader speaks the name of the medicine to assist the blind, elderly, and visually impaired.
Threats • Texas Instruments is promoting a TI-RFID tag that can be read through a purse, wallet, or pocket • This will enable strangers with the reader device to see what you’re wearing or carrying. • Some say marketers will use the tags to identify people and determine their tastes and spending habits through the items they purchase and wear
Airlines will no longer lose luggage Families won’t lose their pets Ex-convicts and car thieves will no longer be able to run away from the police. More convenient than barcodes because barcodes can be easily damaged; therefore, not readable. Advantages
The biggest problem with the RFID tags is privacy. That is why many people are trying to put an end to the distribution of the tags. Another major disadvantage is the price. The sensor alone costs $1,000. Disadvantages
The RFID market is expected to make as much as $10 billion within the decade More companies are purchasing and testing the tags; such as the Michelin tire company RFID could eventually replace the barcode There have already been bills in California, Massachusetts, Missouri, and Utah to put an end to the testing.
