GS1 Standards Autumn Event 8-12 October 2012 – Dublin, Ireland Building Standards to Deliver Business Value

1. GS1 Standards Autumn Event8-12 October 2012 – Dublin, IrelandBuilding Standards to Deliver Business Value Name of Session: RFID Bar Code Interoperability Guideline Time of Session: Tuesday 7.45 Who May Attend: Everyone Speaker names: Michael SarachmanKen TraubAndrew Osborne

2. Anti-Trust Caution GS1 and the GSMP operate under the GS1 anti-trust caution. Strict compliance with anti-trust laws is and always has been the policy of GS1. The best way to avoid problems is to remember that the purpose of the committee is to enhance the ability of all industry members to compete more efficiently. This means: • There shall be no discussion of prices, allocation of customers, or products, etc. • If any participant believes the group is drifting towards an impermissible discussion, the topic shall be tabled until the opinion of counsel can be obtained. • The full anti-trust caution is available in the Community Room if you would like to read it in its entirety.

3. Meeting Etiquette Meetings will begin promptly at designated start times Avoid distracting behaviour: • Place all mobile devices on silent mode • Avoid cell phones • Avoid sidebar conversations Speak in turn and be respectful of others Be collaborative in support of the meeting objectives

Background – Business Requirements • Identified 26 requirements delivered via three initiatives: • Implementation Guideline • 6 requirements • Update EPCIS standards • 2 requirements • GS1 company prefix length determination solution • 7 requirements • Final 11 out of scope or previously resolved • Guideline Objectives • Clarify encoding, decoding and handling of GS1 Keys and attributes using BarCodes and EPC RFID

7. RFID Bar Code Interoperability Guideline • Guideline ratified 21 September 2012 • Available at GS1 Knowledge Center • RFID Bar Code Interoperability Guideline • BarCodes & ID Keys Section

8. Guideline Overview

9. Guideline Scope Enterprise Resource Planning Warehouse Management Supply Chain Traceability Point of Sale

10. Guideline Scope Three Best Practices: • Design business-level applications, databases, and messages to be independent of the data capture method and the data carriers used. • Confine the use of data carrier-specific representations to the lowest levels of implementation architecture. • Adopt best practices for implementing translations between data carrier-specific representations and application-level representations.

11. Data Carrier Independence “Plain” GTIN and Serial Number806141411234586789 Business data GS1 DataMatrix Bar Code containing GS1 Element String (01) 80614141123458 (21) 6789 Gen2 RFID Tag containing EPC Binary Encoding 3074257BF7194E4000001A85 Data Carrier-specific encoding of business data

12. Application-Level Syntax • Key concept: Use application-level syntax at the business application level (not carrier-specific syntax) Right: <gtin>80614141123458</gtin> <serial>6789<serial> Wrong:]C10180614141123458216789 3074257BF7194E4000001A85 Biz App Biz DB Data Capture SW

13. Application-Level Syntax Characteristics • Accommodates every possible value of a GS1 Identification Key without limitation, and so it is capable of representing a key read from any data carrier. • Does not include additional information that is specific to a particular type of data carrier. • Provides only one possible way to represent each distinct key value within the syntax. • Therefore, an application can determine whether two values refer to the same real-world entity by a simple string comparison, with no additional normalization or parsing required

14. Application-Level Syntax

15. Carrier-Specific Syntax

16. Interoperability Principles • Design business applications, messages, and databases to accept data from any data carrier • accept the full range of data values defined by GS1 Standards; do not carry data carrier-specific restrictions to this level • Business applications, messages, and databases should only use application-level syntax: • “Plain” key • GS1 Element String • EPC URI

17. Serial Number Issues • Leading zeros can lead to errors: • 7, 07, and 007 are all different serial numbers according to GS1 Gen Specs • But some applications don’t respect this • MS Excel is a well-known example; it treats a GS1 serial number as an ordinary number •  Avoid the problem by not assigning leading zeros • Variable-length serial number leads to variation in bar code size • QA and packaging design often rely on fixed size symbols •  Avoid the problem by assigning a fixed-length serial • 96-bit RFID tags are limited in serial number capacity •  Avoid the problem by staying within allowed range • Putting it together, the most interoperable serial number allocation policy is: • 10000000000 – 99999999999; or • 100000000000 – 274877906943 • But applications should accept any valid serial number and never add or remove leading zeros
