2. Overview
• RFID Background
• RFID System Components
• Choosing RFID
• RFID Benefits and Applications
3. What is RFID?
• Radio Frequency Identification: Radio Frequency
is an automatic identification method in which
devices called RFID readers use radio frequency
waves to retrieve information from RFID Tags
• RFID is a non line-of-sight technology which
supports automated data capture for many
industries
• RFID can communicate information on a product,
its condition, and its history
4. The (not so) brief history of RFID

6. RFID technology enables auto-identification
through the use of three major components –
tags, readers and software
Tags Readers IT Architecture
• ID Device comprised of a • Data retrieved via an antenna • Software gathers and manages
microchip and an antenna from the RFID tags data
that store/transmit data
• Data passed to systems • Data communicated into
• Memory contains existing enterprise applications
Electronic Product Code (WMS, ERP, etc.)
(EPC) that uniquely
• Common digital language
identifies each product
describes products
• Tags may be active or
passive
7. How the three major components of an RFID
system work together
• An RFID tag may store and transmit data • When an RFID tag detects • The reader decodes data it
like serial number or NDC, model, price, electromagnetic energy, its receives from the RFID tag
date of manufacturer of a tagged product antenna enables the chip to and passes it to a computer
receive and reply to radio system for processing
• May store information about an animal or
frequency signals from an
a person’s identity, details of the account
RFID Reader
to which a tagged smartcard links, or codes
required for security clearance
• May also include built-in sensors that
detect and transmit information about the
condition of a product – e.g., temperature
or tampering
8. TAGS: Depending on the application and physical
requirements, RFID systems can use active (battery
powered) or passive (reader powered) tags
Passive Active
•Powered by RF waves - no internal power •Includes power source and transmitter for
read/write capabilities
•Reflects energy radiated by reader
•Larger than passive tags
•Sized to product
•Additional functionality, such as monitoring
•Used for track and trace, inventory, shipping
temperature, humidity, shock/vibration
•No batteries - Cost <$1 •Cost range $20-$50
•Effective range of up to 30 feet •Effective range of 1000+ feet
•Examples: ExxonMobil Speedpass •Examples: EZ Pass car toll systems, container
environment monitoring
9. READERS: RFID readers are designed to perform
the following functions:
Antenna
Interface to Host Computer
• Interrogate (RS485, RS232/422, ethernet,
• Communicate 802.11 etc.)
• Translate
• Resolve Antenna
Tag Reader
10. There are several peripheral devices and
enabled locations that support an RFID system
Manufacturing/Packaging Distribution Retail/Hospital
• Applicators • Forklift enabled readers • Dock Portals
• Stretch wrap • Perimeter doors • Staging/holding
• Commissioning station • Receiving Dock Portals • Case Crusher/compactor
• Receiving dock portal • POS locations
• Shipping dock portals • Shelving
• Perimeter doors
• Carts and trolleys

11. Passive RFID tags consist of three parts:
1. A silicon microchip: holds information about the
physical object to which the tag is attached
2. An antenna: transmits information 3. Conversion: encases the chip and
to a reader (e.g., a handled, antenna so that the tag can be
warehouse portal, pharmacy or attached to physical object
store shelf) using radio waves
Sample tags
12. RFID systems can only use frequency ranges that have
been reserved specifically for industrial, scientific or
medical applications or for short range devices
LF:
•Uses Magnetic field (Near field)
• RFID frequencies: •Better able to penetrate non-metallic substances
•Ideal for scanning objects with high-water content
•Read range is limited to < 1ft
–Low-frequency (around 125 KHz)
HF:
•Uses Magnetic field (Near field)
–High-frequency (13.56 MHz); and •Can work around goods with high water content
•Practical read range is in inches
–Ultra-high-frequency or UHF (860- UHF:
960 MHz) • Uses Magnetic (Near field) and/or the Electric (Far field)
• Tags are more simplistic and hence less expensive
• Can be used for waters, coupled to metals for greater range
• Used for items, cases and pallets
• Read ranges from an inch to 100+ feet away
Magnetic Field = Inductive Field = Near Field
Electric Field = Far Field
13. The EPC data format used with RFID is more
specific and unique than bar coding
•UPC – Universal Product Code : Associated with Bar Code Technology. A means of
identifying a manufacturer and generic object category.
•EPC – Electronic Product Code: A unique identification code associated with RFID
Technology. A means of associating a manufacturer, object and a specific item via a
unique serial number, allowing reference to a specific item, origination, date of
production, etc.
14. EPC is the basis for RFID
•The EPC stores product information in the form of a value in each tag
•This value is composed of the following elements:
Header (8 bits): EPC Manager (28 bits): Object Class (24 bits): Serial Number (36 bits):
Used to indicate EPC Used to indicate the Identifies the product Provides the unique
version and may company and the group and is identical product serial number
identify variant naming manufacturer – similar to the GTIN* number
schemes. Also can be to company identifier
used for future labeling in GTIN* formats
extensions
*Global Trade Identification Number (GTIN) is the interoperable
data format that USS and EAN numbering systems conform to

16. Factors to consider when choosing passive tags
Considerations
Where will the tags be used? • The location will define the frequency, cycle, antenna pattern, data
Are there other RF activities? rate and power limitations (to avoid interference etc.)
What will my trading • Read only
partners need? • Read/write
• Complexity and cost involved if deploying multiple technologies; e.g.
2D for small items, LF or HF for water based products, UHF for cases
and pallets.
What kind of product will be • Characteristics (round, square, liquid, glass, plastic), cartons, totes
tagged? • Determines size of tag, the kind of adhesive and placement location
How will I build my • Placement of tags
hierarchy? • Alignment
• Aggregation
What kind of environment •Cold Chain
will the tags need to •Humid
withstand? •High temperature
17. While there are factors that can impact tag
performance, knowing how to optimize tags and
system configurations is important for success
Considerations
Tag shape • Antenna shapes can effect performance- more sensitive silicon has
improved this
Tag size • Large antenna mean larger tags and longer read range
Read rate of tags • Rapid rate is suggested
Tag packaging • May effect durability
• Foam, stickers, plastic cases (conversion)
Tag sensitivity • Greater chip sensitivity, longer read range
Tag stacking • Tags stacked closely together may interfere with one another
Number of tag antennas • Readability can be reduced if a tag has one antenna that is
sensitive to orientation
• Double dipole tags alleviate orientation issues, but are more
expensive and are larger
What product is attached to •Cardboard, plastic, clothing
•Metal, water
18. Different types of auto id tags/technologies can
be used at various points in the product hierarchy
Bar Code/ Linear or 2D Passive RFID Semi-Active or Active GPS
L1 -Item L2 -Packaging L3 -Case/Pallet/Unit Load L4 -Container L5 -Vehicle
Passive Tags: Semi-Active Tags: Active Tags: GPS:
• Low cost • Higher cost •High cost (10-100x) • Highest cost
• Long Life • Battery, more memory •Battery and electronics (10Y life) • Extended range –
• Range 1- 30 ft • Range of ~150 ft •Long range ~ 1000+ ft satellite based data
• Typically used for L1–L3 • Typically used for L3-L4 •Larger in size capture – cargo/vehicles
•Wider range of applications • Typically used for L4-L5
•Typically used for L3 – L5
19. RFID is the ‘next generation bar code’ and is
already delivering additional benefits
Bar Code Labeling and Scanning RFID
Price • Low cost • Material is expensive compared to linear and 2D
bar codes –but can return higher ROI
Capacity • Limited space – typically only simple • Can hold substantial amounts of data (96-256 bits)
identifiers (e.g. lot#, SKU) are stored • Can track events and make decisions at lower
• Low granularity of data level, real time = new opportunities for process
• Read only optimization and traceability
• Can read and write information from partners
Flexibility • Line of site reading required • No line of site required - proximity only resulting
• One simultaneous scan per read in simpler handling of goods
• Multiple simultaneous tag scans per read
Accuracy • Human intervention opens possibilities for • Fully automated and nearly error-free
errors • O.H.I.O. principle – Zero Human Interventions
Operations – reducing labor requirements
Durability • Labels can be easily damaged, destroyed •Tags are more durable
and duplicated •Tags can operate in harsh environments

27. What factors are influencing RFID adoption?
Considerations
Standards • Standards that govern how readers, tags and network infrastructures exist
Cost of tags • Reduction in the cost of tags is dependent upon demand
• RFID will likely remain more expensive than bar codes unless benefits
beyond current systems are identified
• Closed supply chain tracking can reuse tags - open supply chain seldom
does
Consumer Privacy • Consumers may have concerns that RFID device embedded in product may
transmit personal data
Mixed Solutions • Complicates infrastructure – some trading partners using different
identification (2D bar coding or linear)
Varying data formats • Writeable tags may contain varying data format, making them unreadable
except by customized readers
28. What will drive the future of RFID?
