Transcript

 

Experts predict Radio Frequency Identification (RFID) technologywill replace the bar code in the next decade, because of the efficiencies it creates. Unlike bar codes, RFID tags can be made in tiny formats, some no larger than a grain of salt, and the tags don’t have to be manually scanned. Instead, RFID tags send out a radio signal that can be captured at a distance and at indirect angles by RFID readers, eliminating the need for an employee with a hand-held scanner to read a label. Retailers and manufacturers hope to save millions by automating the shipping and inventory process and reducing theft using RFID. In late August 2003, Wal-Mart announced it would require its top 100 suppliers to put RFID tags on all pallets and cases of shipped products by January 2005 and require the rest of its suppliers to begin using RFID tags by 2006. Privacy advocates fear RFID will become as omnipresent as video surveillance and give marketers another method of tracking people’s movements and shopping behaviors.

The retail industry isn’t the only sector moving toward RFID. On September 4, 2003, the San Francisco Public Library Commission approved plans to start tagging library books with RFID chips by 2005-06 to speed up lines at book check out counters, locate misplaced books, and reduce theft. With the cities of Berkeley and Santa Clara also considering the transition to RFID, civil liberties groups, such as the Electronic Frontier Foundation, have begun to raise concerns the technology will give anyone with an RFID reader, including homeland security agencies and businesses, the ability to track and identify library patrons and the books they borrow after they leave the library.

Recent RFID Events Timeline

 

Background

 

What is RFID?

 

Radio Frequency Identification (RFID) tags are conceptually similar to, though much more advanced than, price bar codes found on most products people buy and to the magnetic strips found on credit cards and driver’s licenses.

A bar code, for example, pulls up a product name and price when it’s passed over a scanner designed to read the code. The strip on the back of a driver’s license contains all of the information that’s printed on the front of the card and can be read quickly by a computer when swiped though the machine.

RFID tags are tiny electronic computer chips that can be placed, for example, on pallets of factory-sealed products to readily tell shippers the quantity, type, date manufactured and destination as they pass through warehouse doors that are equipped with an RFID reader (also called an antenna). The tags can be read from 25-30 feet away and at indirect angles, removing any need for a person with a hand-held scanner to read the product.

RFID antennas can be placed on walls, shelves and doorways. Not only can they read the RFID tags that pass by, they can also electronically add brand new data to the tag, such as shipping date, arrival date, and condition.

 

What are other uses of RFID?

 

RFID technology is making its way into people’s everyday lives in a number of areas:

  • Wal-Mart has announced plans to require its top 100 goods suppliers to tag shipping cases and pallets with RFID technology by 2005 and to require the rest of its suppliers to start using RFID tags by 2006.
     
  • Wal-Mart and Procter & Gamble have tested RFID tags on Max Factor Lipfinity lipstick sold at the Wal-Mart store in Arrow, Oklahoma. Store shelves equipped with Webcams allowed Procter & Gamble researchers in Cincinnati, Ohio, to watch customers as they picked up and looked at the lipsticks. In a separate trial, Wal-Mart and Gillette have tested the usefulness of placing RFID tags on Gillette razor blades sold at Wal-Mart stores. RFID antennas on store shelves tracked when customers picked up razors, when they put them back on the shelf, and when they carried them to the register. The tests were designed to give insight on shopping behavior, prevent shoplifting, and to alert employees when shelves needed to be re-stocked.
     
  • Seattle’s 24 public libraries are in the process of tagging their millions of library books, videos, and audiotapes with RFID chips and will begin using RFID tracking systems in spring 2004 to speed up book check out lines and help locate misplaced books. The cities of Berkeley and Santa Clara are considering a similar transition.
     
  • RFID technology is what makes California’s FasTrak automated bridge toll payment program possible. Drivers with FasTrak’s RFID tags inside their car windshield can cross bridges without having to stop and pay a cash toll because the RFID tag contains a prepaid dollar amount (e.g., $50), and as the car passes the toll plaza, an overhead antenna reads the tag and automatically deducts the appropriate toll from the prepaid account.
     
  • RFID is also used in the microchips frequently implanted in pets with information on the name of their owner, address, phone number, and more to help animal shelters readily identify and reunite lost animals with their owners.
     
  • Alexandra Hospital in Singapore used RFID tags to track the movements of nurses, doctors, and visitors who came in contact with SARS patients. The European Union is considering embedding miniscule RFID tags into the fibers of European currency to reduce counterfeiting.

At about 20 to 50 cents per tag and $1,000 per reader, RFID systems are still too expensive for widespread use. Some experts project, though, that as demand grows, manufacturing costs will drop and within the next decade the use of RFID technology will become much more prevalent.
 

Are there concerns with RFID?


The Privacy Rights Clearinghouse, Consumers Against Supermarket Privacy Invasion and Numbering (CASPIAN), and the Electronic Frontier Foundation have raised several concerns about the potential privacy implications of RFID technology.

Their main concern has to do with who will have access to the data RFID technology allows companies to collect and how it that data can be aggregated. For example, it would be theoretically possible for businesses to tag everything with RFID, allowing RFID antennas anywhere to scan the contents of people’s purses, wallets, shopping bags, not to mention identifying the makers of the clothes, jewelry, and shoes they’re wearing. The ability to collect, aggregate, and manipulate this information could give businesses a powerful marketing tool if they can use it to profile and identify potential customers as they walk through the mall entering stores and restaurants.

While the retail uses of RFID appear to raise the greatest concern, some believe other uses, such as tagging library books with RFID chips, pose a threat as well. If people can be identified and profiled according to the library books they read and carry with them, homeland security agencies seeking to identify potential terrorists and businesses wanting to profile customers’ interests may use RFID readers to track and identify people and the library books they’re carrying with them. Some experts predict that if uniform technology standards are developed and RFID becomes ubiquitous, the entire contents of people’s handbags, shopping bags, and even the clothes they wear, will be identifiable as people walk through a doorway equipped with an RFID reader at stores, airports, and government buildings.

 

What laws limit businesses from tracking people?

 

Technology already allows people to be tracked from their morning coffee stop to their evening trip home from work. In many cases, the federal or state government has acted to restrict how businesses can use the information they collect on people.

  • Every purchase made by ATM or credit card, leaves a detailed electronic record with both the store and the bank, which over time can indicate interests, shopping patterns, likely income levels, and more to financial institutions. Federal law allows businesses to share that information freely with their many affiliates and subsidiaries.
     
  • People who sign up for loyalty card programs at their local supermarket are essentially allowing their grocer to keep tabs on what they buy and how much they spend over days, weeks and years. California law restricts how that information can be used.
     
  • People who watch cable or satellite TV often don’t realize their viewing records can be monitored and used for marketing purposes by their provider. However, federal and state laws prohibit cable and satellite companies from selling that data to others.
     
  • Libraries and video stores keep track of the books and movies people check out, but federal laws ban them from revealing that data to anyone.
     
  • Phone companies keep track of the local and long distance calls their customers make, though federal and state laws strictly prohibit them from listening in on phone conversations or selling information about who their customers call.
     
  • Many employers read employee e-mail, track keystrokes, and follow employees as they visit Internet websites at work. This practice isn’t precluded by law and employers aren’t required to tell their employees that their actions may be monitored.
     
  • Internet businesses frequently drop bits of software, such as "cookies" and "web bugs" on the computers of people who visit their sites to track people’s whereabouts online.
     
  • Meanwhile, as people walk down city streets, enter businesses, drive through intersections or ride public transit, surveillance cameras may be recording their every move. Some cities have begun to test whether they can more effectively reduce crime by combining surveillance cameras with face scanning technology and criminal databases containing mugshots of former inmates and suspected terrorists.

 

Recent RFID Events

 

  • November 15, 2003. MIT’s Media Lab in Cambridge, Massachusetts, holds an RFID privacy workshop.
