Barcodes – What is It ?
• A barcode is an optical machine-readable representation of data, which
shows certain data on certain products.
• Barcodes are available as linear or 1D (1 dimensional).
• They also come in patterns of squares, dots, hexagons and other geometric
patterns within images termed 2D (2 dimensional) matrix codes or
symbology.
1D Barcode 2D Barcodes

Barcodes – Who is GS1 ?
• GS1 is an international not-for-profit association dedicated to the
development and implementation of global standards and solutions to
improve the efficiency and visibility of supply and demand chains globally
and across multiple sectors. The GS1 System of standards is the most
widely-used supply-chain standards system in the world.
• GS1's main activity is the development of the GS1 System, a series of
standards designed to improve supply-chain management. The GS1 System
is composed of four key standards: Barcodes (used to automatically identify
things), eCom (electronic business messaging standards allowing automatic
electronic transmission of data), GDSN (Global Data Synchronisation
standards which allow business partners to have consistent item data in
their systems at the same time) and EPCGlobal (which uses RFID
technology to immediately track an item).

Barcodes – What is GS1-128 ?
• GS1-128 symbology is used to encode trade item data for logistics units
such as cartons, cases, and pallets that are not intended to pass through
retail point-of-sale (POS). The use of this symbology supports fast and
accurate tracking of inventory and other specific data in the supply chain.
• GS1-128 symbology is used to uniquely identify trade items, logistics units,
and returnable assets in the supply chain. The symbology not only encodes
trade item data, but provides a method for encoding and sharing a large
variety of different specific data types defined by the GS1 System, such as
the Serial Shipping Container Code (SSCC), Best Before Date, Batch / Lot
Number, and Serial Number.

Barcodes – GS1-128
• This is accomplished by
creating and defining a list
of Application Identifiers
(AI’s) that uniquely defines
both the data format and its
meaning. More that 100
different AI’s are described
in the latest version of the
GS1 General
Specifications, a GS1
System standards
document.

Barcodes – Unattended Scanning
Distribution Centres in Start Track / Coles /
Myers use the following equipment

10. RFiD – What is It ?
• Means of automatically identifying objects
• Typical operation
• – 64 bits to few kilobits of data
• – Range ~1cm to ~10m
• – 50-1000 tags per second
• Reader transmits radio frequency energy
• Provides power for the tag
• Enables communication to and
from the tag
• Different operating frequencies
are possible

11. RFiD – RFID Frequency Bands
LF
HF UHF Microwave
125kHz
13.56MHz 860-960MHz 2.45GHz
134kHz
Relatively Reasonable cost Latest technology Smaller antennas
expensive and performance Legislation varies (and tags)
Low range Discreet tags, still between regions Typically less
Robust, but bulky quite low Range range
tags
Asset Library, Transport, Very Specific low
Management, Transport, Document Read Range high
Harsh Medical, document Management, Read count.
Environment, Management New Library Laboratory Etc
Animal ID Application

12. RFiD – UHF Band Legislation
• Most Promising RFiD Band – Suitable for Supply chain, but there are
International considerations.
• Need to consider performance implications
• Numerous conflicts still to be resolved

13. RFiD – Power
• Systems discussed so far are passive
• No battery in tag; all power comes
from reader Carrier RF Wave
• Possible to build a battery into the tag
• Increased complexity, Passive Cheapest, no battery
size and cost
Semi-passive Much more range
• Improved performance (range)
(battery and
& functionality
assisted) reliability
Active (battery High performance,
powered) sensors, cost!

14. RFiD – Why RFiD ?
• Alternative technologies
• Barcodes (traditional and 2D)
• Magnetic strips
• Vision systems
 ‘Simultaneous’ identification
 Robust, reasonable operating distance
 No line of sight; automated reads
× Not as cheap as some alternatives
× Some problematic items

15. RFiD – EPC – Electronic Product Code
• UPC as defined by GS1

16. Supply Chain – What is It ?
• A supply chain is a system of organizations, people, technology, activities,
information and resources involved in moving a product or service from
supplier to customer.

17. Supply Chain
• Supply chain
activities transform
natural resources,
raw materials and
components into a
finished product that
is delivered to the
end customer.

18. Supply Chain – Example
Supplier Order
Requisition Goods
Request Received
Issue on Site Pick & Pallet
Receive on Site Shipping

19. Supply Chain
Stage 1 - Goods Received with Optional Tagging
When goods Arrive from supplier, Pending Orders on the
system are downloaded to Rugged Mobile
Computers that scan received Item against the
purchase order and upload back to Purchasing / ERP
system items received. All transaction Executed in
Batch Process and data collected on mobile device is
sent back using Desk Cradles.
Items not Bar-coded or Tagged will
Be Done so at this stage.

20. Supply Chain
Stage 2 – Picking and Palletising
Replenish Request from sites are then picked from
warehouse, and at the same time palletising.
Pallets include a mixture of Products, but Each Pallet
Label or Tag associated all items on the pallet.
All operations executed using Rugged Mobile
Computers and uploaded to ERP system.

21. Supply Chain
Stage 3 – Shipping
Pallets are then associated with a container.
Each container has an RFiD Tag.
Containers are then shipped by Truck, Ship etc with a
destination associated with.

22. Supply Chain
Stage 4 – Received on Site
Each container as arrives on site is scanned to indicate
received on site.
Each container as unpacked and opened is scanned
and pallet unpacked also associated with storage
location.

23. Supply Chain
Stage 5 – Issue on Site
Items in Stock on site are then issued to various staff or
department and again using mobile devices to log
and track against project cost centre usage.

24. Supply Chain
Stage 6 – Requisition Request
Remote sites are raising requisition requests to
replenish required inventory. Again this can be done
using rugged mobile computers.

25. Rugged Wireless
Mobile computers

Truck RFiD Tag

26. Summary
• Barcoding , RFiD and Mobility Technologies are already available, and
proven. Recommend to use GS1-128 Barcodes and GS1 EPCGlobal RFiD.
• Industry standards are in place and managed by GS1 globally.
• Recommend to use both Barcoding and RFiD in final solution to Be more
cost effective. Barcoding for Lowest SKU and Cartons, and RFiD for Pallet /
Container / Trailer / Vehicles etc.
• Work closely with suppliers so they provide inventory already bar-coded, to
reduce Running costs (Prevent Labelling on goods Received).
• Select appropriate Hardware and software to fulfil Chevrons requirements.
Intermec is highly recommended brand By Existco.
• Plant and test with small scale pilot to prove processes re working as
required.
