Introduction

 IEEE 1609 standards define PSIDs to be administered by
  IEEE
 Procedures for registering, fees, guarantees of uniqueness,
  configuration control are all TBD
 Mitretek examined method for Electronic Product Code
  (EPC) registration for applicability to PSID assignment
   – Used for RFID-based product identification and supply
     chain applications
   – Millions of unique codes maintained
   – Mapping of legacy numbers into EPC
       • Bar codes
       • Global Trade Item Numbers (GTIN)
   – Computer database and network access for e-commerce
                                                            3




What is EPC?

 The tag, including a chip, an antenna and the packaging
  substrate
 A numbering scheme that uniquely identifies all objects

 Connects physical objects to computer networks
                                                                           4




Basic Format of EPC
  Header     EPC Manager             Object Class       Serial Number
             Number

      Assigned by                             Assigned by EPC
      EPCGlobal                               Manger Owner
    •Header
    – identifies the length, type, structure, version, and generation of
    the EPC
    •EPC Manager Number
    – entity responsible for maintaining the subsequent partitions
    •Object Class
    – identifies a class of objects
    •Serial Number
    – identifies the instance
                                                    5




Formats

 Two formats-64 bit and 96 bit
 Existing numbers can be encoded into EPC number
   – Global Trade Item Numbers
   – Universal Product Codes
   – Serialized Global Location Numbers
   – DoD constructs
 EPC is not flat space
   – Has header and company prefix
   – Filter values
   – Serial numbers
                                                              6




Who’s Who?

 European Article Numbering-Uniform Code Council
   – was a supply chain standards family name, formally the
     EAN.UCC System, that included product barcodes.
 EAN International was the global office for the more than
  100 Member Organizations around the world. In 2005 the
  organization changed its name to GS1.
 The Uniform Code Council (UCC)
   – was the Numbering Organization in the USA to
     administer and manage the EAN.UCC System. In 2005
     the UCC changed its name to GS1 US
                                                                  7




How Do I Get a Number?

 Apply for membership in GS1 (your regional organization)
 Pay membership fee
   – GS1 will assign globally unique company prefix
   – Use GS1 standards to create globally unique number
   – Membership includes many services in addition to number
 The Global Electronic Party Information Register (GEPIR) is a
  distributed database that contains basic information on over
  1,000,000 companies in over 100 countries.
   – You can search by GTIN (includes UPC and EAN-13), SSCC
      and GLN numbers or by company name in some countries.
   – Results can be returned in HTML or XML for some countries.
 The service is provided jointly by different GS1 Member
  Organizations.
 GS1 provides Electronic Data Interchange guidelines for e-
  commerce.
                                                                  8




What Does it Cost?

 Initial Subscription Fee.
   – Each subscription includes the use of the designated
      number of EPC Manager Numbers and access to the
      EPCglobal Network for a one year period beginning on
      the first calendar day of the month following the date
      payment is received.
 Annual Renewal Fee.
   – The Annual Renewal Fee for the designated number of
      EPC Manager Numbers and access to the EPCglobal
      Network will be 20% of a subscriber’s total subscription.
                                                      9

Some Issues

 EPC numbers are based on standards and contain a unique
  company prefix
   – PSIDs are currently undefined
 Several types of supply chain number standards exist
   – Standardized methods for encoding to EPC
 EPC Number is hierarchical with well defined fields
   – Distributed databases and information networks help
     construct electronic supply chain management
   – PSID is flat-space
 Data bases and electronic commerce services administered
  by GS1
   – Included in annual fee
   – Companies can calculate ROI when using EPC
