RFID & Retailing Jonathan Wareham
What is RFID? • RFID is an technology that uses radio-frequency waves to transfer data between a reader and a movable item to identify, categorize, track... • RFID is fast, reliable, and does not require physical sight or contact between reader/scanner and the tagged item
What is RFID? -- The Tags • Tags can be read-only or read-write • Tag memory can be factory or field programmed, partitionable, and optionally permanently locked • Bytes left unlocked can berewritten over more than100,000 times
Tag ID Only Programmable Database Pointer Mission Critical Information Portable Database Read Only (Factory Programmed) WORM - Write Once, Read Many times Reprogrammable (Field Programmable) Read/Write (In-Use Programmable) RFID System Basics
What is RFID? -- The Tags Tags can be attached to almost anything: • pallets or cases of product • vehicles • company assets or personnel • items such as apparel, luggage, laundry • people, livestock, or pets • high value electronics such as computers, TVs, camcorders
Are All Tags The Same? Basic Types: • Active • Tag transmits radio signal • Battery powered memory, radio & circuitry • High Read Range (100 meters) • Passive • Tag reflects radio signal from reader • Reader powered • Shorter Read Range (10cm – 5 meters)
RFID the Supply Chain Tag Antenna Reader Middleware Supply chain execution - Backend SCE or ERPsystems receives Information • Process information from reader • Filters data • Sends data to backend servers - Transmits identification data to a reader • Transmit data tomiddleware • Associates tag info with product info - Coiled antenna ofreader creates magnetic field with coiled antenna of tag
How far, how fast, how much, how many, attached to what? Low Frequency • No regulation • Penetrate materials (water, wood, tissue well) • Slow read speed • Small range • No penetration of iron and steel Medium Frequency • Little data, small distance • Thin tags • Low cost • High data rates • Govt regulated • Non mental penetrating High Frequency • Penetrate materials • Small tag size • High data transfer • Long range • Non-water or tissue penetrating • Non-regulated in some regions • expensive
Where can RFID add value? • From Manufacturing • Through Distribution • Transportation • Into a Store’s Back Room Inventory • On the Shelf • At the Cash Register • Out the Door as an anti-theft device
Portal Applications Bill of Lading Material Tracking
Portal Applications • Limited number items at forklift speeds • 8’ X 10’ doorways • Electronic receipt & dispatch • Wrong destination alert • Electronic marking • Pallet/container item tracking
Conveyor / Assembly Line Read / Write Operations Higher Accuracy than Bar Code
Conveyor / Assembly Line • Up to 450 fpm • 60+ items per container • Inexpensive tunnels • Longer tunnel more items • Electronic receipt • Sorting • Electronic marking
Hand Held Application Categories Wireless Batch Fixed Station
Application Examples Material Handling By Destination Wireless / Batch Inventory Management Material Handling Aggregate / De-aggregate Where is it going? Where has it been? Should it be here? Where is it? What is it? What is inside the box? Material Handling Inspecting / Maintaining Has this been repaired? Is this under warrantee? Has this been inspected? Is this complete? What is the asset’s status or state? What have I assembled or disassembled? How many do I have? Do I have enough?
Shipping Validation Tote/Box/Unit Level Inventory
HazMat Smart Label • Low power > long range • 1024 bit memory • Read/write/lock on 8 bits • Advanced protocol • Efficient multi-id Lock data permanently • 12 ms/8 byte read 25ms/byte write • Group select Broadcast write • 40 tags/second Anti-collision
ApplicationRequirements • Wal-Mart-Suppliers will mark inbound cases and pallets with RFID - 1 January 2005 - May, 2003 specification calls for ≈256 bit read/write tag • U.S. Department of Defense-Draft RFID policy to be completed by 18 September 2003 - To issue final policy in July of 2004 that will require suppliers to put passive RFID tags on selected case/pallet packaging by January of 2005. Draft policy calls for passive tags (est. 256 byte) and active tags
Is RFID GPS? NO!
Electronic Article Surveillance • Typically retail theft deterrence applications • Arguably first and most widespread commercial use of RFID • “1-bit” tag • Cheap, passive
Electronic Toll Collection • Toll tags speed regular users through toll gates • RFID tag on windshield identifies vehicle and enables toll deduction from account
Railcar Tracking • 99% of every North American railcar in interchange service equipped with RFID

Product Recall • Remember Ford and Firestone? • TREAD Act • RFID pilots underway to track tires from manufacturer tovehicle
Baggage Tracking • Positive Passenger-Bag Matching initiatives (PPBM) • Bar code systems work today but line-of-sight requirements make complicated solutions • 1 to 2 billion tags/year • Many pilots to date • Tag price is key
Top 100 Suppliers: • Suppliers will mark inbound cases and pallets with RFID - 1 January 2005 - May, 2003 specification calls for ≈256 bit read/write tag • 1 EPC tag per carton – 100% read on conveyor • 1 EPC tag per pallet – 100% read at Inbound dock • Conveyor speed of up to 600 feet per minute • 3 Texas Distribution Centers • January 2005
Why??? • Stock management /perishables (field to fork) • In-stock levels • Invoice reconciliation: damaged, deductions, performance penalties, etc. • Scan Based Trading or VMI • Improved analytics & POS data • All reads available to suppliers within 30 minutes

Guidelines for using RFID • Bar codes cannot be used • Counting versus identification (reverse logistics) • Use of 3Party logistics and suppliers • Data collection is chaotic (battlefields, hospitals, retails shops) • Exact configuration of the good must be maintained • Counterfeit protection • High Risk scenarios, drugs, hospitals • Collecting data outside of retailer (smart refrigerators, medicine cabinets, etc)
