10. What´s NEW - EPC Gen2V2?
• Crypto solution for even more applications
(e.g. road tolling)
• European privacy concerns addressed
• File management available for more data
with different owners
10

11. NEW, but not Gen2V2 specific
• Mature products in high volume
• Better tag sensitivity
– Read range continuously increased (> 20 m)
– Area surveillance (> 1000 m2)
– Movement direction detection
11

12. End-users´ Requirements
• Ensure high success rate (almost 100%)
• High reading speed
• Avoid unwanted (false positive) reads
12

13. End-users´ observed Issues
• Reading of tags is sensitive to
– Distance from the reader
– Type of the RFID label
– Material of the tagged item
• RF effects on performance
– Absorption
– Reflection
– Detuning
13

14. End-users´ observed issues
• Dense reader environments
– Readers must be configured not to disturb
each other
– How to prevent reading tags, which are in the
field of the neighboring reader
• Used reader
14

15. Solution?
Conformance
Performance
Interoperability
15

16. Conformance - Finding the bits
• Compare in the air with what the reader
and tag are supposed to do
• See whether commands sequences make
sense
• Check waveforms and timings
• Trigger of error cases
16

17. Conformance Test Results
New Crypto
commands of ISO/IEC
29167
New EPC Gen2V2 and
ISO/IEC 18000-63REV1

18. Performance Tests
• Make sure your tag can be read in individual
regions
– Tag performance is frequency dependent.
• Verify the sensitivity of the tag
– The better the sensitivity, the higher the read
range
• Verify the range and sensitivity of the reader
– The better the sensitivity, the higher the read
range
18

19. Performance Test results
Write range
Read range
Detuned

20. Interoperability Tests
• Check whether various readers can
coexist
• Evaluate how well different devices
perform if operated at one site
• Very important in the current retail setup
20

21. Interoperability Tests
5.0ms
Miller M= 4 backscatter - 5 ms for one EPC/UII
21

22. Certification
• GS1 EPCglobal requirements
• ISO/IEC requirement
• ARTESP, SINIAV, Brasil-ID requirements
• Application requirements
22

23. Success of NFC ...
• ... relies on many factors
– Availability of devices (critical mass)
– Availability of features
– Standards
– Applications
– Usability
– User habits
– ...
– Interoperability
23

24. NFC Standards
ISO/IEC 14443B
ISO/IEC 15693
ISO/IEC 14443A

25. Conformance Tests
• Test whether implementation meets
requirements of standard
• ISO/IEC test standards
• NFC Forum
• EMVCo
25

26. Interoperability Tests
• Test actual products against each other in
realistic application scenarios
• Unveil standard weaknesses or ambiguities
• Typically covers all layers
– physical to application
• PlugFests
• Interoperability Test Lab
26

27. NFC Interoperability Tests
27

28. Failure Reasons
• Application software
• Protocol
• Data content
• Command sequence
• Timings
• RF settings
• Product design (materials)
• Antenna design
28

29. Performance Optimization
• Performance evaluation with
the help of automated NFC
interoperability tests
• Failure analysis
• Modification of parameters
and design
29

30. Performance Optimization
