Some rfid hype

Some RFID Hype

RFID AutoID technology has received considerable media attention, innovation ideas, and controversy.  For example:

"Study shows RFID benefits for retailers. Retailers can expect extensive inventory and labor cost savings from the adoption of radio frequency identification (RFID) technology, but some consumer product manufacturers will face higher costs and delayed benefits from adopting the technology. That is the conclusion of a new report on RFID and the Electronic Product Code (EPC) from global management consulting firm AT Kearney."( from http://logistics.about.com/b/a/042898.htm )

"Dvorak Slams RFID. It's bad news, claims John Dvorak. Those tiny radio transmitters that promise convenience and flexibility are just another path toward big brother domination. And it's going to get a lot worse. ( from http://ct.eletters.whatsnewnow.com/rd/cts?d=181-480-1-278-107259-23183-0-0-0-1 )

"A Manufacturer of soft drinks can identify with the click of a button how many containers of its soda cans are likely to reach their expiration date in the next few days and where they are located at various grocery outlets.( from CACM, August 2005, p. 103 )

RFID: The History


Technical aspects of rfid

Technical Aspects of RFID

Standards? The RFID industry suffered from a proliferation of standards, according to Sue Hutchinson, director of product management for EPCglobal. EPCglobal had two GEN-1 standards, while ISO had two UHF air interface standards. (December 17, 2004)

  • Tag Power Source

  • Tag Components

  • Read - Read/Write

  • Anti-Collision

  • Who talks first?

  • Protocol

Ultimate focus of this SIP activity


Rfid tags come in different forms can be attached to almost anything

Class V tags

Readers. Can power other Class I, II and III tags; Communicate with Classes IV and V.

Class III tags:semi-passive RFID tags

Class 0/Class I:read-only passive tags

Class IV tags:

Active tags withbroad-band peer-to-peer communication

Class II tags: passive tags with additional functionality

RFID Tags Come in Different Forms – Can be attached to almost anything

  • Tags can be attached to almost anything:

    • pallets or cases of product

    • vehicles

    • company assets or personnel

    • items such as apparel, luggage

    • people, livestock, pets

    • high value electronics e.g., computers, TVs

  • Many applications

Primary focus


Tag types active

RFantenna

Battery

RF & Digital Circuitry

Tag Types: Active

  • Active:

    • Standard: None, Mainly Manufacturers Proprietary Systems/Protocols

    • Range: Generally 300 Feet or less

    • Battery powered / limited life

    • Used Predominantly in Transportation Systems (rail, toll systems, trucking, container).

    • Characteristics: Tag with Internal Power Cell Mounted to Item or container/pallet/box, Interrogator Queries Tags, Uploads/Downloads Data. Does not transmit all of the time. Data Capacity Varies.


Tag types passive

Digital Logic & Control

Tag Types: Passive

Memory(EEPROM)

  • Passive:

    • Standard: None/many, Mainly Manufacturers Proprietary Systems/Protocols (uses back scatter technology)

    • Range: Typically Measured in “Inches”, Working Toward “Meters” (dependant system layout, interference, etc.)

    • Used Predominantly in Retail Systems and Transportation Systems.

    • Characteristics: Small Tag Loaded with License Plate Data

    • Typically Mounted to End Item, Reader Captures Data as Item Moves Through Choke Point (door, pathway, frame, etc.).

    • Data Capacity Limited.

RF antenna

Tag types semi active

Memory

(EEPROM)

RFantenna

Battery

Digital Logic & Control

Tag Types: Semi-Active

  • Semi-Active or Battery Assisted Passive

    • On-board battery power source

      • Uses Passive Technology (no transmitter)

      • Greater range but higher cost (less than active)

      • Requires less power from reader

      • Finite life

      • Can use thin batteries (little change to form factor)


Tag types read vs read write

Tag Types - Read vs Read/Write

  • Read Only:

    • Information can only be read from an RFID device – programmed at manufacture

  • User Programmable

    • WORM - Write Once Read Many - Ability to initialize an RFID device outside of the RFID manufacturer’s facility after manufacture

  • Read/Write:

    • Information can be read from or written to an RFID transponder during the time it is presented to a reader/writer

    • Typically asymmetric read and write operating range


Technical considerations

Anticollision

Ability to communicate with several transponders simultaneously

Important in longer range readers

Must be implemented in the silicon of the RFID device

Who Talks First

Tag Talks First (TTF)

After the tag is energized, it sends out a signal that says “I am here”

Reader Talks First (RTF)

As reader sends out energization signal it says “who is there”

Problems

With TTF you can get tag pollution but slower total read time

Compatibility issues?

Technical Considerations


Protocol

Protocol

  • The method used to talk to a tag

    • Modulation method

    • Error correction

    • Anti-collision technique

    • Message format

    • Commands

    • All frequencies have their pros and cons

  • ISO standards

    • Proprietary or standards-based

  • Government regulations

    • Varies from country to country


Part 1 rfid technology application areas

RFID System Considerations

  • Multiple Tag Reading in Same Field

    • Anti-collision

  • Sensitivity to Orientation

    • A single orientation or omni-directional

  • Hardware Set-up

    • Environment can affect performance

    • Tag Sensitivity to Metallic environments


Part 1 rfid technology application areas

Reader Characteristics

  • Stationary or handheld

  • Weather-proof or industrialized

  • Typical read ranges vary from a few centimeters to a few meters

  • Read Range is dependent upon:

    • Broadcast signal strength

    • Size of broadcast antenna

    • Size of transponder antenna

    • The environment – Metallic, Liquid

  • Multi-frequency readers


How compare to 2d barcodes

How compare to 2D barcodes


Barcode examples many types

Barcode Examples – Many types

UPC A

Maxi-code

Codablock

PDF 417

Code 49

QR Code

Data Matrix


Current technology bar coding

Current Technology: Bar-coding

UPC A code

18 digit alphanumeric code used for identifying flow of package and billing information

Large database used to support this system – 18 terabytes

Maxi-code

Determined by the locations of bars around a central dot

Contains information for the destination address of the package as well as weight and size specs.

requires special equipment and a stable environment free from movement to obtain a read of the information


Rfid vs bar coding

RFID vs. Bar-coding

  • Bar-coding Disadvantages

    • Code must be clearly readable

      • free from dirt, smudging or other damage

      • This is problem with the constant movement of packages

    • Code must be in a position that can be easily read by a scanning device

      • Optical lasers are usually used for scanning

    • Code must be within a short distance to be read

      • Typically within 3 feet

    • Only one code can be scanned at a time

    • Codes must be a reasonable distance apart

  • The use of RFID can eliminate many of the problems associated with bar-coding technology.


The future a hybrid world

The Future? -- A Hybrid World

  • Traditional bar codes

    • Will remain the dominant auto ID technology for the foreseeable future

      • Lowest cost, broadest applicability, huge infrastructure investment

  • 2D bar codes

    • Will be increasingly adopted for value added applications

      • Portable data files, supplementary retail coding etc.

  • RFID

    • Will be increasingly adopted where non-line of sight, read/write, multiple detection offers real advantages


Implementations of rfid

Implementations of RFID

  • Retail is the current driving force

    • Wal-Mart

    • Target

  • Others

    • Department of Defense

    • UPS

    • Other logistics firms


Things to consider

Things to consider

  • Price of tags

    • Currently about 10 to 50 cents each

    • If just $0.01, $250,000,000 to tag every P&G product

    • Chicken and Egg

  • Uses

    • Wal-Mart will be collecting existing data

    • Many possibilities

  • Technology matures

    • Cheaper and standards

  • Privacy (e.g., “RFID chips in world soccer tournament tickets questioned”)

    • All 2.9 million tickets for FIFA World Cup soccer tournament in Germany include an RFID smart tag

  • Already exists

  • RFID technology detects if an item is removed from a store without tag being deactivated

    • Amorphous magnetic strips

    • Destructible tuned circuits

  • But - Existing technology cannot uniquely identify goods

  • New RFID technology provides significant features:

    • Able to write SKU number into transponder

    • Automatic inventory with a hand held reader

      • Anti-collision mandatory for this feature

    • Cash registers can automatically ring up merchandise

Why do people buy rfid

Why do people buy RFID?

  • Traditional Reasons:

    • Reduction of direct labor (80%)

      • Hand-held reader vs. Fixed reader

    • Protection and tracking of assets

      • Animals – Inventory – Tires – Access Control - etc.

    • Cost Structure reduction

      • Out of stock - 7.8% – “walk aways”

    • Only technology that will work

      • When bar codes don’t work

        • (dirty / line of sight)

  • New Reason:

    • Mandated

Winners losers

Winners & Losers ?

  • AT Kearney study

  • Retailers benefits

    • Reduce inventory by 5%

    • Reduce store & warehouse expenses by 7.5%

    • Reduce “out of stock” $700,000 per $1B

  • Manufacturers costs

    • High impact (expensive) v. low impact (cheap)

    • Low impact: $155M in capital costs

      (assuming $.15/tag, 10 year horizon, 12% cost of capital


What about closed loop enterprise applications

What about “closed loop” & Enterprise applications?

  • RFID technologies have been available for a decade

  • For many applications the tag cost was too high

  • Supply Chain volume reduce tag costs

  • All those applications are still waiting for an RFID solution
