Introduction
Our Work
• Carton HF （ 13.56MHz ） RFID system substitutes for
barcode system on the cigarettes production line .
• Pallet
Dynamic data recording and modification with UHF （ 860-900MHz ） RFID system for stack–by-stack transportation of cigarettes .
Thirty cigarette-cartons on a pallet make a stack.
Why RFID?
• Advantages of RFID compared to barcode
1.No need of light and larger read range …
2.Writable …
3.Long life time and high reliability …
Others …
Frequency Selection
• 125KHz• 13.56MHz• 433MHz• 860-900MHz• 2.45GHz• 5.8GHz
Requirements:a. The auto-identifying
requirement is realized at a minimum cost.
b. The interrogating range on the production line must be no less than 5 centimeters, and on pallet transport no less than 30 centimeters
c. The pallet tag must be writable and its duration of writing data into the memory should be as short as possible.
Implementation
Reconstructed production line
Pallet with UHF Tag
UHF Reader Antenna

The Front End
Problems and Solutions
Problems and Solutions
• HF reader fails to read• Cartons fall down from
the suction cup• UHF tag writing ability
test• Data accordance check• Data redundancy and
compact
Results and Future Work
Percentage of normal stacks to
total stacks
Factors of abnormal stacks
and their percentages
Results and Analysis
• Repeat• Hybrid• In-accordance• Write Failure • Memory Empty• Read ID Failure
This is because the non-deterministic nature of RFID slotting or back-scatting communication protocols [14].

Achievements
• The HF RFID usage is not so much satisfying.
• The UHF RFID system is exciting.
-It reduces the transport time of each stack .
-It reduces the damages to the cigarette-cartons .
-It paves the way for the realization of digital warehouse management.
Future Work
• RFID technology is adopted in the whole tobacco industry chain
From production line to warehouse management, until to retail process on the shelf, it will realize visible tracking of products, physical distribution management based on real time information
Conclusions
• HF• UHF• Conclusively This pilot project has testified some advantages of
RFID technology.
