A Scene from Mission Impossible (1996)
… The federal agent in charge of the most secrete FBI database was tagged with a piece of fabric less than an eighth of an inch square. The tag showed where he was in the building and allowed perpetrators (led by Tom Cruise in the movie) to know when to penetrate the heavily-guarded security system to get the data file, the NOC-list, a list of all FBI undercover agents working around the world. …
Another Scene from Demolition Man (1993)
… The criminal Simon Phoenix (played by Wesley Snipes in the movie) escaped from the San Angeles cryogenic prison. Signaled by the ID chips and sensors embedded in the vehicle taken by the criminal and planted to the forearms of security personals and staffs, the city-wide security system was able to quickly locate the criminal in the city and, identify and access the status of the deaths and injuries of the security personals and staffs (remotely) caused by the escapee. …
What is RFID? Radio Frequency Identification Device Holds a small amount of unique data – a
serial number or other unique attribute of the item
The data can be read from a distance – no contact or even line of sight necessary
Enables individual items – down to the proverbial “can of beans” to be individually tracked from manufacture to consumption!
RFID Market 10 millions in 2002. 91.5 millions in 2003. 3.1 billions (1.3 billions for retail
alone) in 2008. Minimum growth rate of 23%
annually. IDC (Jan. 2004), The Freedonia Group
(Dec. 2003), Insight Research (Dec. 2003), ABI (Jul. 2003).
RFID Tag Attributes

Passive RFID Tags “Traditional” tags used in retail security
applications Tag can be programmed at manufacture
or on installation Tag is powered by the high power
electromagnetic field generated by the antennas – usually in doorways
The field allows the chip/antenna to reflect back an extremely weak signal containing the data
These passive tags form the basis of the Auto-ID designs, and, if manufactured in billions, will come down in price from $0.97 to $0.05 in the next 2 years.
Active Tags Battery Powered tags
Have much greater range – 100m Hold much more information –
Kbytes Can integrate sensing technology
Temperature, GPS Can signal at defined time Multiple tags can be recorded at
once Used for higher value items
Shipping containers Babies Electronic assets
Cost between $20 and $40 per item
Life between 2 – 4 years
A Brief History – An Internet of Things
Not a new technology. Identifying enemy war planes since
the World War II and during the Gulf war.
Civilian applications: highway toll tags, the control of paroled criminals, the prevention of missing kids, and others.
A Brief History – An Internet of Things
Auto-ID Center, 1999. Version 1.0, Sept. 2003. Wal-Mart, DoD, Metro, 2003. Auto-ID Lab, Oct. 2003. EPCglobal, Oct. 2003.
Auto-ID Center (1999) A partnership of almost 100 global companies and
five research universities: the Massachusetts Institute of Technology in the US, the University of Cambridge in the UK, the University of Adelaide in Australia, the Keio University in Japan, and the University of St. Gallen in Switzerland. (The Fudan University in China, the sixth research
university in August 2003) Goal: Apply the technology to objects in our daily
lives so computers would be able to “see” the identities of these objects and to form an "Internet of things”.
Mission: Develop the infrastructure and building blocks of this special internet and to develop its future standards.
Wal-Mart, Metro (2003) Request their major biggest suppliers to apply
RFID tags to merchandise pallets going to their distribution centers.
Metro (Dr. Hans-Joachim Körber, chairman and CEO; Zygmunt Mierdorf, CIO)
Store testing in Reinhold, Germany since April, 2003: intelligent scale, self-scanning shopping cart, information station.
Begin the installation of intelligent scale and self-scanning shopping cart in all stores in Apr. 2004.
Major supplier compliance by Nov. 2004. Wal-Mart (H. Lee Scott, CEO; Linda Dillman,
CIO) Major supplier compliance by Jan. 2005 (Expect 25%-
36% of full compliance). All supplier compliance by Dec. 2006.
EPCglobal (2003) Converted from Auto-ID Center on Oct. 23, 2003. A neutral, not-for-profit standards organization and a
joint venture between EAN International and the Uniform Code Council (UCC).
Mission: Develop and oversee the standards of electronic
product codes (EPC) by using the RFID technology, Provide registry service of the codes, and Coordinate with International Standards Organization
(ISO) for their review and ratification. Implementation Task Force (ITF): Board of Directors,
Operating Committee, User Action Group, Technical Steering Committee, and Technical Action Groups.
The “Internet of Things” proposed by the Auto-ID Center is now called the EPCglobal Network.

EPCglobal Network
Introduction Basic elements How does it work? Business applications
Introduction EPC: Electronic Product Code Provide information about the location
of items, the history of items, and the number of items in a supply-chain.
A new technology to identify, track, and manage products in a supply chain.
Revolutionizing the way we manufacture, sell, and buy products in the future.
Internet of Things.
Basic Elements
EPC EPC tags and readers Savant Object Name Service (ONS) Physical Markup Language (PML)
Electronic Product Code (EPC) Next generation of product identification.
Similar to the U.P.C. (Universal Product Code) or bar code.
Adopt the basic structures of the Global Trade Item Number (GTIN).
GTIN, an umbrella group under which all existing bar codes fall and supported by the Uniform Code Council and EAN International, the two main bodies that oversee international bar code standards.
Can associate an infinite amount of dynamic data over the EPCglobal Network.
Divided into numbers that identify the manufacturer, product, version and serial number.
EPC Code Two standards: 64 and 96 bits.
e.g. 613.23000.123456.123456789 (96 bits) Header (8 bits), Version number EPC Manager (34 bits), Originator of EPC
(product manufacturer), up to 268 million companies, e.g., the Coca-Cola Company.
Object Class (20 Bits), Product type or SKU, up to 16 millions per company, e.g., Diet Coke 330 ml can, US.
Serial Number (34 Bits), Product item, up to 68 millions per class, e.g., a specific 330 ml can of Diet Coke .
EPC Tags and Readers EPC is stored on a special tag,
generally referred as RFID tag or Smart Label. The tags are applied to products during
the manufacturing process like bar codes. The readers “communicate” to the
tags by sending radio waves and then pass the EPC and possibly other data to a program called Savant running on a computer.
Savant Formulate production information request as a
query. Send the request to the Object Name Service (ONS),
which acts like a yellow page directory, to retrieve the network address of a product information server.
Forward the request to the product information server.
The program can run on different computers distributed throughout an organization.
Possible tasks include: data smoothing, reader coordination, data forwarding, data storage, and task management.
Object Name Service (ONS)
Similar to the Domain Name Service (DNS) in the computer network.
Provide the network address service of product information.
Built-in redundancies to avoid the crash of a product information server in the network.
Physical Markup Language (PML) A “language” for describing physical
objects such as products. Based on the widely accepted
eXtensible Markup Language (XML). Include data that changes constantly
(dynamic data) and data that changes over time (temporal data). Dynamic data: temperature of a shipment of
fruit, or vibration levels from a machine. Temporal data: an object's location.
Supply Chain – Global Vision
Business Applications
Manufacturing, Logistics, and Material Handling
Inventory Tracking and Management
Safety and Security Customer Service
Manufacturing, Logistics, and Material Handling
Instant identification of a shipping container plus all of the items inside.
Incoming pallets or cartons can be routed automatically for cross-docking or delivery directly to the manufacturing and customer sites.
During assembly processes, items can be routed and recorded for their movements.
For shipping, packers can quickly locate and aggregate all the items needed to complete an order.
Pharmaceutical companies can use RFID to ensure medicines are put into correctly labeled packages.
Inventory Tracking and Management
Track work-in-process and finished goods inventory.
Assists the discovery of sought items, misfiled materials, unreturned containers, and expired products for improved warehouse operations.
Enable shippers to lower their material costs.
Provide an audit trail that can be used to bill customers if materials are not returned.
Track medication dispensing, laboratory samples, and blood bags in hospitals.
Automatic replenishment of inventory.
When an item is removed from a shelf or when inventory falls below safety stock levels, a replenishment notice can be sent out automatically.
Safety and Security Hands-free access to secured buildings and safeguards
corporate properties or amusement parks. Ensure only authorized personnel are admitted to authorized
facilities. Alzheimer’s disease patients can be prevented from wandering out
of a medical facility. For Pediatrics, only staff or parents may be permitted to check out
infants or children. Children separated from their groups or parents in amusement
parks or public facilities can be located easily. Detection of counterfeit products and medicine and provides
anti-shoplifting protection and theft deterrence on retail merchandises, computers, furniture, files, library books, videos, CDs, and other objects.
Talking prescription bottles to ensure that patients take the correct medication by “speaking” the drug contents, dosage instructions, and drug interaction warnings to the patients with the help of a reader and text-to-speech conversion software (especially helpful for blind and vision-impaired people).
Cashless Payment Promotes quicker service while keeping
account information confidential. Prepay and load the monetary value onto RFID tags
or wristbands and recharge the tags or wristband after the stored value has been depleted.
Pay-at-pump, Pay-at-booth. Prepaid passenger fare cards for public transit.
Guest identification cards / keys for cashless payment, as a room key, and for access control to the health clubs and other facilities at hotels, restaurants, and entertainment facilities.
Customer Service Speedy check in,
check out, and browsing. books/videos, and
garments in desired style, size, and color.
Product information. Returns and warranty
repairs. Lifetime tracking and
product authentication.
