RFID in the Library
Mick FortuneLibrary RFID Ltd.
A 30 minute guide
![Page 2: 30 minute guide to Library RFID](https://reader033.fdocuments.us/reader033/viewer/2022061118/546970a8af795946718b53bf/html5/thumbnails/2.jpg)
On today’s tour…
• RFID - What it is• How it works and what it’s used for• What do libraries love about it• Things to consider• Where to get advice
![Page 3: 30 minute guide to Library RFID](https://reader033.fdocuments.us/reader033/viewer/2022061118/546970a8af795946718b53bf/html5/thumbnails/3.jpg)
The Basics
![Page 4: 30 minute guide to Library RFID](https://reader033.fdocuments.us/reader033/viewer/2022061118/546970a8af795946718b53bf/html5/thumbnails/4.jpg)
What it is
Radio Frequency IDentificationData is stored on integrated circuits (called
“chips”)Can be read and written many times overData is “broadcast” via an aerialAll attached to a “form factor”

Tags come in all shapes and sizes…
![Page 7: 30 minute guide to Library RFID](https://reader033.fdocuments.us/reader033/viewer/2022061118/546970a8af795946718b53bf/html5/thumbnails/7.jpg)
…in many forms
![Page 8: 30 minute guide to Library RFID](https://reader033.fdocuments.us/reader033/viewer/2022061118/546970a8af795946718b53bf/html5/thumbnails/8.jpg)
…using different frequencies…Band LF HF UHF Microwave Frequency 30–300kHz 3–30MHz 300 MHz–3GHz 2–30 GHz
Typical RFID Frequencies
125–134 kHz 13.56 MHz 433 MHz or 865 – 956MHz 2.45 GHz 2.45 GHz
Approximate read range
less than 0.5 metre Up to 1.5 metres 433 MHz = up to 100 metres 865-
956 MHz = 0.5 to 5 metres Up to 10m
Typical data transfer rate
less than 1 kilobit per
second (kbit/s)
Approximately 25 kbit/s 433–956 = 30 kbit/s 2.45 =100 kbit/s Up to 100 kbit/s
Characteristics
Short-range, low data transfer
rate, penetrates water but not metal.
Higher ranges, reasonable data rate (similar to GSM phone), penetrates water
but not metal.
Long ranges, high data transfer rate, concurrent read of <100 items, cannot penetrate water or metals
Long range, high data transfer rate, cannot penetrate water or
metal
We are (mostly) here!

…for different purposes
• Road Tolls• Travelcards• Warehousing• Drug security• Brand Protection• Cats

Including of course…Libraries!
![Page 11: 30 minute guide to Library RFID](https://reader033.fdocuments.us/reader033/viewer/2022061118/546970a8af795946718b53bf/html5/thumbnails/11.jpg)
The Context
![Page 12: 30 minute guide to Library RFID](https://reader033.fdocuments.us/reader033/viewer/2022061118/546970a8af795946718b53bf/html5/thumbnails/12.jpg)
What do libraries love about it?
• Self service– liberates staff and borrowers– extends opening hours
• Stock management– easier stocktaking– tracing items
• …and much more
![Page 13: 30 minute guide to Library RFID](https://reader033.fdocuments.us/reader033/viewer/2022061118/546970a8af795946718b53bf/html5/thumbnails/13.jpg)
How the Process Works
RFID in action: Library Self Service
![Page 14: 30 minute guide to Library RFID](https://reader033.fdocuments.us/reader033/viewer/2022061118/546970a8af795946718b53bf/html5/thumbnails/14.jpg)
RFID Device(s)
Self service loans – a simple model
Library Management System (LMS)Library
Management System (LMS)
Item(s)
Reads data from items
Sends data to LMS
Receives data from LMS
Clears security
Processes rules
![Page 15: 30 minute guide to Library RFID](https://reader033.fdocuments.us/reader033/viewer/2022061118/546970a8af795946718b53bf/html5/thumbnails/15.jpg)
Library Management System (LMS)
RFID Device(s)
The (Slightly) More Complex Model
Data exchanged RFID/LMS
Borrowers and items use
different technologies
Clears security
Processes rules
Item(s)
SIP
plus …?
Pay fines

and what else?
• ILL• Accessions• Smart displays• Interactive stock• Guiding• Offline circulation• New models for library management
systems

The Issues
![Page 18: 30 minute guide to Library RFID](https://reader033.fdocuments.us/reader033/viewer/2022061118/546970a8af795946718b53bf/html5/thumbnails/18.jpg)
(Some) Things to Consider
• Standards• Choice and Interoperability• Privacy
![Page 19: 30 minute guide to Library RFID](https://reader033.fdocuments.us/reader033/viewer/2022061118/546970a8af795946718b53bf/html5/thumbnails/19.jpg)
Standards
• For data – so we can all read the tags (ISO 28560/UK Data Model)
• For communication – to improve performance, map onto tag data and increase range of services (SIP 3.0/NCIP/Web services)
![Page 20: 30 minute guide to Library RFID](https://reader033.fdocuments.us/reader033/viewer/2022061118/546970a8af795946718b53bf/html5/thumbnails/20.jpg)
ISO 28560-2 and Data Models
• Other standards are available• UK agreed on ISO 28560-2• UKDM is a simpler subset• RFID Alliance roles
– Development– Compliance testing
![Page 21: 30 minute guide to Library RFID](https://reader033.fdocuments.us/reader033/viewer/2022061118/546970a8af795946718b53bf/html5/thumbnails/21.jpg)
Choice and Interoperability?
• Choose the solutions you want– Kiosks, shelf readers, accession tunnels
• Test interoperability– Are tags fully compliant with standards?– Will solutions work with other LMS?
![Page 22: 30 minute guide to Library RFID](https://reader033.fdocuments.us/reader033/viewer/2022061118/546970a8af795946718b53bf/html5/thumbnails/22.jpg)
Privacy
• EU directive• Data on tags
– For Items– For Borrowers
• A real concern?
