Question 1
· Tracking apparel: Clothing maker Benetton planned to embed retail items with RFID tags. The implanted devices would enable Benetton to track individuals and inventory their belongings by linking a consumer's name and credit card information with the serial number in an item of clothing.UHF tags are a new generation of RFID technology that provide faster data transfer speeds and longer read ranges. Marks & Spencer has already used tracking devices extensively in its food supply division.

· Tracking consumer packaged goods (CPGs): Gillette, Wal-Mart, and the U.K.-based supermarket chain Tesco are teaming up to test specially designed shelves that allow for real-time tracking of inventory levels. The "smart shelves" will be able to read radio frequency waves emitted by microchips embedded in millions of shavers and other products. So far, Wal-Mart executives say the company plans to use RFID chips only to track merchandise, and will remove the tags from items that have been purchased.

· Tracking tires: Tire manufacturer Michelin recently began fleet testing of a radio frequency tire identification system for passenger and light truck tires. The RFID transponder is manufactured into the tire and stores tire identification information, which can be associated with the vehicle identification number (VIN). Critics argue the tags could ultimately become tracking devices that can tell where and when a vehicle is traveling.

· Tracking currency: The European Central Bank is moving forward with plans to embed RFID tags as thin as a human hair into the fibers of Euro bank notes by 2005, in spite of consumer protests. The tags would allow currency to record information about each transaction in which it is passed. Governments and law enforcement agencies hail the technology as a means of preventing money-laundering, black-market transactions, and even bribery demands for unmarked bills. However, consumers fear that the technology will eliminate the anonymity that cash affords.

· Tracking patients and personnel: Alexandra Hospital in Singapore recently began a new tracking system in its accident and emergency (A&E ) department in the wake of the Severe Acute Respiratory Syndrome (SARS) scare. Under this system, all patients, visitors, and staff entering the hospital are issued a card embedded with an RFID chip. The card is read by sensors installed in the ceiling, which record exactly when a person enters and leaves the department. The information is stored in a computer for 21 days. Officials say that the technology enables health care workers to keep tabs on everyone who enters the A&E department, so that if anyone is later diagnosed with SARS, a record of all other individuals with whom that person has been in contact can be immediately determined.

· Payment systems: Today, a wide range of merchants and retailers are looking for ways to implement radio frequency (RF) wireless payment systems. Sony and Phillips are leading the way. The two corporations will soon begin field testing an RFID system called Near Field Communication (NFC), which will enable RFID communication between PCs, handheld computers, and other electronic devices. The companies envision that consumers will log on to their personal online portal by swiping their smart cart—embedded with a Sony or Philips RFID—which will be read by a RFID reader plugged into the USB port on the computer. Next, consumers would shop online, say, for tickets to a local event. The consumer would pay for the tickets online, download them to their PC and then transmit them with NFC technology to an RFID tag in their mobile phone. Then, at the event, consumers would wave their cell phone near a reader in the turnstile, and be automatically admitted.
Question 2
While corporate giants tout the merits of RFID technology, civil liberties advocates point out that the ability to track people, products, vehicles, and even currency would create an Orwellian world where law enforcement officials and nosy retailers could read the contents of a handbag—perhaps without a person's knowledge—simply by installing RFID readers nearby. Such a fear is not unfounded. Currently, some RFID readers have the capacity to read data transmitted by many different RFID tag. This means that if a person enters a store carrying several RFID tags—for example, in articles of clothing or cards carried in a wallet—one RFID reader can read the data emitted by all of the tags, and not simply the signal relayed by in-store products. This capacity enables retailers with RFID readers to compile a more complete profile of shoppers than would be possible by simply scanning the bar codes of products a consumer purchases.
The proposed uses of RFID tags pose exponentially greater risks to personal privacy. Many technology experts predict the development of a seamless network of millions of RFID receivers strategically placed around the globe in airports, seaports, highways, distribution centers, warehouses, retail stores, and consumers' homes, all of which are constantly reading, processing, and evaluating consumers behaviors and purchases. In addition to undermining a consumer's ability to enjoy a lifestyle in relative anonymity, critics of the technology counter that the information gathered by RFID readers could be obtained by the government for surveillance or monitoring the activities of citizens, or even misused by hackers and criminals. Even more, the ever-expanding use of RFID chips would leave no aspect of life safe from the prying eyes of retail and corporate giants. Chips integrated into commonplace products such as floor tiles, shelf paper, cabinets, appliance, exercise equipment, and grocery and packaged products would allow even our most intimate activities to be monitored.
Opponents of RFID tags have proposed measures to side-step the chips' relentless information-gathering, ranging from disabling the tags by crushing or puncturing them, to simply boycotting the products of companies which use or plan to implement RFID technology. One way to destroy the tags is to microwave them for several seconds. Another method is to obstruct the information gathered by RFID readers by using blocker tags. When carried by a consumer, blocker tags impair readers by simulating many ordinary RFID tags simultaneously. Blocker tags can also block selectively by simulating only designated ID codes, such as those issued by a particular manufacturer.
Question 3
No, they shouldn’t be deployed
While barcodes have historically been the primary means of tracking products, RFID systems are rapidly becoming the preferred technology for keeping tabs on people, pets, products, and even vehicles. One reason for this is because the read/write capability of an active RFID system enables the use of interactive applications. Also, the tags can be read from a distance and through a variety of substances such as snow, fog, ice, or paint, where barcodes have proved useless.
Currently, RFID tags are not widely used in consumer products because the price of the tags is still prohibitively expensive. However, as companies push for enhanced means of tracking products and profiling consumers, the increased demand and production of RFID technologies will drive down prices.
This composite information is vastly superior—and more invasive—than any data that could be obtained from scanning bar codes, or even loyalty cards. Frequent shopper cards link consumers to their purchases, but this limited information gives retailers only a narrow view of a consumers' in-store purchasing trends. In contrast, RFID systems enable tagged objects to speak to electronic readers over the course of a product's lifetime—from production to disposal—providing retailers with an unblinking, voyeuristic view of consumer attitudes and purchase behavior.
In an attempt to soothe consumers' fears, companies have argued that most items tagged with RFID chips can't be tracked beyond an operating distance of about five feet. However, while this may be true today, industry experts say plans for building far more sensitive RFID signal receivers are in the works.
As RFID technology becomes more advanced, consumers may ultimately lose all ability to evade products implanted with chips. Corning researchers have developed tiny, barcoded beads that are invisible to the human eye. The microscopic beads can be embedded in inks to tag currency and other documents, and even attached to DNA molecules. They can also be added to substances like automobile paint, explosives, or other products that law enforcement officers or retailers have a strong interest in tracking. Researchers say the technology could be ready for commercial use in three to six years.
