RFID : ABSS Logistic Event
What is RFID
RFID is Radio Frequency Identification
> Used for automatic identification or data collection (AIDC)
Similar to bar code in concepts
> RFID tag stores data ~ barcode label
> RFID reader ~ barcode scanner
Radio waves vs. Light waves
No Line-Of-Sight required
Read through various environment conditions
One-way or Two-way (RO or RW)

RFID basic components
Tags Host ComputerAntenna Reader
• Device made up of an electronic circuit and an integrated antenna
• RF used to transfer data between the tag and the antenna
• Portable memory
• Read-only or read/write
• Active or passive
• Usually attached to specific items
• Receives and transmits the radio frequency signals
• Wireless data transfer
• May be integrated in the reader for short range applications or structural for warehouse applications
• Communicates with the tag via antenna
• Receives commands from application software
• Interprets radio waves into digital information
• Provides power supply to passive tags
• Reads/writes data from/to the tags through the reader
• Stores and evaluates obtained data
• Links the transceiver to an applications, e.g. ERP

Tag Power Source
Passive
> Power by energy from reader
> Backscatter technology
> Smaller, Lighter, less expensive
> Almost unlimited life
> Shorter range
> Requires higher power from reader
Active
> On-board battery power source
> On-board transmitter
> Greater range but higher cost
> Requires less power from reader
> Finite life
RFID : ABSS Logistic Event
Tag Power Source
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 (but longer than active)
> Not create RF pollution

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

RF Properties
Radio Lucent or Radio Friendly
> lets radio waves at this frequency pass through it without any
substantial loss of energy
Radio Absorbent
> blocks, reflects, and scatters RF waves.
Radio Opaque
> A material can allow the radio waves to propagate through it
but with substantial loss of energy
> The RF-absorbent or RF-opaque property of a material is
relative, because it depends on the frequency

RFID Production Process
RFID : ABSS Logistic Event
Lean Production
Lean manufacturing involves
identifying and eliminating non
value adding activities (waste)
and focuses on the start-to-end
value streams rather than the
idea of optimising individual
departments in isolation.
Type of wastes:
1. Overproduction: excessive lead and
storage times
2. Waiting: unproductive equipment
usage.
3. Transport : non-value adding for
product move
4. Inappropriate processing: system
too complex than necessary
resulting in the excessive transport
and poor quality
5. Unnecessary inventory
6. Unnecessary motion
7. Defects : waste of raw material and
production time.

off line manner
Be able to write information to support
individual station validation
Sustain harsh environment such as wet, high
temperature, chemical resistance.
Validate individual station control
Reusable tag
RFID : ABSS Logistic Event
Why RFID
Data memory feature
Key functions Business benefits
Product Material Monitor material variations.
Recipe (BOM) Ensure the right raw material is
used for production
Labor Improve labor utilization
Tools Determine impact of tool
variance, improve tool utilization.
Station Track material location and
enforce process validations
Process Optimize routing
All data -Quickly determine root cause of
product failure
-Greater product traceability

Why RFID
Harsh environment

Box
RFID Tag on
Pallet
Not many technologies can withstand this environment.
RFID : ABSS Logistic Event
Why RFID
Tag validation
Automate data collection
> Reduce waste on unnecessary motion movement : bar code
scanning and manual data entry
> Reduce waste on unnecessary transport: move product for
scanning
Automate data association
> Help to ensure that the right product is on the manufacturing
process.
> As a result of reducing human data entry/error, RFID can reduce
waste on defects, overproduction, or unnecessary inventory,
RFID : ABSS Logistic Event
Why RFID
Tag validation Production visibility in real time manner
> Average time spent on work in each step
> Average time spent on transportation on each step
> Total time a single item takes to complete the entire process.
> Know where the waste is, and which action takes to reduce the waste
> Reduce overproduction
> Unnecessary inventory
RFID : ABSS Logistic Event
Conclusion
Type of wastes RFID Strength
Overproduction Increase production visibility
Waiting Increase production visibility
Transport in production Reduce movement on products for data
scanning
Inappropriate processing Reduce human data entry or bar code
scanning
Unnecessary inventory Increase production visibility
Unnecessary motion Reduce human data entry or bar code
