Tagging Challenge (1)
HF RFID
Tag
UHF RFID
Tag
HF Tag UHF Tag
Tag are bulky and obvious Small and slim
Short reading distance – 1.2m Long distance – 2.5 to 5m
Unregulated Frequency Regulated Frequency
Orientation coverage; high Orientation coverage; high
Low false read at gate Moderate false read at gate
Tag cost still higher than UHF Lower tag cost
Tagging Challenge (2)
HF Tag on Book UHF Tag on Book
Good No Good Moderate
Self-Check Challenge
HF Station UHF Station
Limited multi items check due to limit in
dist (4-6)
No Limit, as long as reader power support
mass tags reading
Well control read/write zone Difficult to control consistence read/write

CD/DVD still not good CD/DVD still not good
Good location reading on shelf Difficult to identify item location on shelf
EAS Gate Challenge
HF Gate UHF Gate
Limited detection range 1.5 to 3.5m depend on tag orientation
Well control read zone Difficult to control consistence read zone
CD/DVD still not good CD/DVD still not good
Close body reading – good Close body reading – poor
Low false read Moderate false read especially items
within 3-5 meter range
Bulky Panels Antennas can be easily hide (wide

So, which is good?
NF UHF UHFHF
Andrew Nathanson (Venture Development Corp), predicts that the availability of EPC Gen 2 near-field UHFhardware will change that scenario, since the technology operates well in liquids and metals and reads more
items at a faster rate (about 500 percent faster) than HF. It can encode RFID tags at a rate 75 percent faster
than HF, Nathanson said, but the technology has not caught up with science.
Best of both Technologies
NF UHF
NF UHF, HF 13.56MHz or UHF 860-960MHz
Technology Strengths Weaknesses
NF UHF � Works good in metal fluid
� Low tag cost
� Good protocol, anti-collision
� Fast data transfer
� Less interference by noise
� Can be both near and far field
� EPC Gen 2
� Higher equipment cost
� Regulated frequency
� NF/FF tag limited variety
EPC Gen 2
HF � Moderate data transfer
� Moderate tag cost (not true)
� Unregulated frequency
� Read through human body
� RFID Tag is too big to be hidden
� Can be shielded by metal
UHF � Longer read range
� Small tag size
� Lower tag price
� Fast data transfer
� EPC Gen 2
� Sensitive to tag orientation
� Regulated frequency
� Sensitive to liquid and metal
� Higher equipment cost
� UHF signals can be reflected by environmental objects

My 5 cents worth comments
� NF UHF - higher advantage than HF and UHF on Item Tagging� Potential of NF UHF still not fully explore;
� lower cost with more adoptions,
� (NF) distance still short,
� not too many players in market,
� limited tags applicable for library
� Lack of market knowledge on NF UHF� Lack of market knowledge on NF UHF� No one Tag fix all items; thickness, material, characteristic will
affect its effective read/write distance� Patented technology but still ok� Lack mature application, coming development of NF UHF
determine market share of item tagging� Lack of Tag suppliers� Lack of additional functions on NF UHF, sure as security, EAS,
memory space
Conclusion
� HF is still currently most mature and popular solution for Library
� HF still have wider range of products and vendor choices, largely proven in term of operation and cost saving
� UHF faces many challenge in RFID library
� NF UHF potential, but need more time, sites implementation to prove its capabilities
� NF UHF potential, but need more time, sites implementation to prove its capabilities
� Although UHF/NF UHF tag is slightly cheaper than HF, later will have cheaper or same
� HF will still be dominate in library for few more years, with NF UHF technology getting mature then, will see the shift of market
� Users need to be more receptive and patient to give space for such technology to mature
Thank You! See u at Booth 15
