SUBCOMMITTEE ON NEW TECHNOLOGIES
Informational Hearing: RFID Technology and Pervasive Computing
State Capitol, Room 113
August 18, 2003
2:00 p.m.
While new technologies can make businesses more efficient and shopping
more convenient, many carry implications for personal privacy that need
to be explored, understood, and resolved as new technologies become a part
of everyday life. Radio Frequency Identification (RFID) devices are small
electronic tags that can be read, much like a bar code is read, by hand
held scanners or readers mounted on countertops, walls or doorways. RFID
technology was invented more than 30 years ago, but recent technological
advances have reduced both the size and cost of RFID chips and have prompted
businesses to consider embedding the tags in products from razor blades
to cell phones to track them from manufacturer to warehouse to store shelf
to cash register. Privacy advocates predict RFID will become yet another
method of following people after they leave the store and compiling data
on their movements and shopping behaviors.

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:
-
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.
-
Wal-Mart and Gillette recently 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 project was
designed to help give the retailer insight on shopping behavior, prevent
shoplifting, and to alert employees when shelves needed to be re-stocked.
-
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 and Consumers Against Supermarket Privacy
Invasion and Numbering (CASPIAN) 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.
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.
