  • 1. Presentation by Existco Barcode & RFiD in Supply Chain Putting the Pieces Together 13th April 2009, Perth, Australia
  • 2. Who am I – Eli Abitbol • Director of Existco • B.Eng (Hon) Electronic Systems • Involved In Barcoding, RFiD, POS, Mobility in the Past 15 Years. Who is Existco • Small Business, Specialising in Barcoding, RFiD, Point of Sales, Wireless and Mobility Solutions • Microsoft Certified Partner • GS1 Alliance Partner • Various Vendors Partner
  • 3. Agenda Barcode RFiD Supply Chain Summary Questions
  • 4. Add text title 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
  • 5. Add text title 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).
  • 6. Add text title 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.
  • 7. Add text title 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.
  • 8. Add text title Barcodes – GS1-128 - Example (01) GTIN (17) Expiry (10) Batch (21) Serial GTIN Expiry 01/01/2010 Batch Number Serial Number Prefix Prefix No
  • 9. Add text title 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 Barcode / RFiD Reading Proposed Hardware Label Printer / RFiD Reader Industrial wireless Access Point Carton Label / RFiD Fixed RFiD Reader & Antenna Pallet / Container / Trailer / 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.
