Agenda

• Introduction
• Library Perspective on Systems
• Industry Adoption of ISO 15693-3
• Security Implementations
• Current Status
• The AFI Issue
• Looking Forward

Introduction

• Public and Academic Libraries
• Barcode-based systems
• Integrated Library Systems starting in 1980s
• EM and RF Security Systems from 1970
• Self Checkout Systems from 1993
• RFID Intro to Libraries in 1999
• Replace barcode and security with RFID
• Proprietary Systems
• Tags from Philips, TI, Mitsubishi Materials,
  Tagsys (ISD/Gemplus)

Library Perspective

• Proprietary systems are usually more expensive to
  purchase and maintain
• Vendors may not remain viable in the long term
  (need for interoperability)
• Library items will survive for many years in some
  cases
• Standardization can help provide
  equipment/vendor/tag interoperability
• Security is mission-critical for many libraries

ISO 15693-3 / 18000-3 Mode 1

• ISO Tags sold by most library RFID vendors (3M,
  Bibliotheca, Tech Logic, Tagsys, Libramation,
  Omron, ST Logitrack, Intellident, others)
• Many library RFID RFPs specify these tags
• Provides standard tag platform. Next step is
  standardizing contents of tag
• Basis for Dutch NBD standard and Danish draft
  standard

Security Implementations

• Electromagnetic Strips
• RFID security by proprietary EAS function (ISO
  and non-standard)
• RFID security by AFI
• Detection system issues inventory command with
  AFI specified
• One AFI assigned to items checked in, another to
  items checked out
• Allows other applications to search for items
  that are checked out

7
Current Status

• Several hundred libraries using ISO tags. Many
  are using AFI.
• Danish standard first effort to standardize
  library industry on particular AFI values
• EDItEUR has applied for one AFI code for the
  global library industry

8
The Issue

• Not all ISO silicon offers EAS
• EAS implementations proprietary
• Industry demands interoperability
• The majority of ISO tags support AFI
• AFI provides a way to effectively implement
  security with interoperability
• Application interference is undesirable

9
Looking Forward

• Options
• Continued, but standardized, use of AFI for
  security
• Two assigned codes would be desirable
• Is there another way to provide security based on
  ISO standard functions?
