6ESTIIC-Project CABRFID
Cabrales Cheese Traceability based on RFID
technologies

http//www.nrw.de
Project Partners University of Dortmund,
Department of Logistics (FLog),
GERMANY Laboratoria Interprofesional Lechero de
Asturias (LILA), SPAIN Project Duration July
2006 December 2007 Goal Evaluate the possible
use of RFID for the documentation of each
production step of Cabrales Cheese
7Current Problems and Issues
- European Union
- Law aims at tracking tracing (EU regulations
no. 178/2002, 1935/2004) - Control of food quality and safety
- Farmer
- Limited space inside the ripening caves
- Profit vs. Restrictions
- Controller
- Proof of origin
- Authenticity control
- Customer
- Food Safety
- Transparency of the Supply Chain
8Cabrales Cheese
- Blue Cheese with penicillium molds
- 3 Sorts of Milk Cow, Sheep, Goat
- Stays up to 6 months in ripening caves
- Customers pay up to 30 EUR / kg
- Completely handmade
- Small production lots
- Local delicacy in Asturias, rarely available in
other areas
9Requirements for using RFID with Cabrales Cheese
- Tagging the cheese from the very beginning
- Raw milk (more or less liquid) in a bowl
- Withstand the cave conditions
- Withstand the acid ripening process
- No chemical alteration of the cheese allowed
- Tags should be reusable
- Low reading distance
- No bulk reading wanted
- High memory capacity of the tag
- Every production step is to be stored in addition
to the cheese's specific data
10Software requirements
- Protection against manipulation
- Changing dates of production steps
- Changing cheese composition data
- Simple usage
- Farmer's don't want to study manuals
- Available for different operating systems
- E.g. .NET Application
- Multilingual
- English
- Spanish
- German
11Hardware requirements
- Reading / Writing must be done with a handheld
device - No electrical power in some caves
- Each cheese is manually handled
- The handheld device must be resistant against the
cave conditions - 100 humidity
- Must survive falling on the cave's floor
- RFID Reader should be in Compact Flash format
- Increased flexibility
- Independent from specific handheld computers
12Software solution (Prototype)
- Developed in C
- About four thousand lines of code
- Application takes 125 KB of memory space on the
mobile device in addition to the necessary .NET
framework
13Screenshots of the software
14Hardware solution (Prototype)
RFID-Tag Anchor
Final Application
RFID-Tag, Anchor Clamp
15Chosen transponder type
- ITG Assa Abloy IN TAG 200
- HITAG S Chipset
- 2048 Bytes of memory
- About 5 cm reading distance
- 125 kHz frequency
- Material PA6 modified, food compatible
- Chemical protection class IP68
16The RFID-enhanced production process
- An RFID-tag is attached to each cheese from the
very beginning - Lot number
- Serial number
- Composition
- Manufacturer / Farmer's ID
- The data is read and updated for each step
- Production day
- Shelf
- Cave in / cave out
- Drying Room
- Packaging
- Each RFID-tag is removed during packaging, and
the data is stored into a central database - The serial number is printed on the packaging
17Current and new production process

New Process

Packaging
- Removal of transponder
- Data stored in central Database
- Labelling by a transponder
- Printed lot number on the tag
- Identification point
- All Data locally saved on the transponder chip
18Summary of the developed solution
- Requirements of the EU are fulfilled
- Tracking Tracing of each individual cheese is
possible - Food safety is enhanced
- Running costs are very low because the tags and
plastic application parts are reused - Due to a low reading distance and the
restrictions in the software the complete
procedure is process-safe - The customer gets the chance to retrieve detailed
information about the cheese he bought without a
necessary knowledge about RFID technology
19RFID is on everyone's mind
- The future technology RFID is already deep-seated
in the present. - Wireless chips connect the physical world of
products to the virtual world of digital data. - Inefficiencies in value creation and efforts
about inner security are driving the demand for
wireless chips. - RFID stands for an all-embracing structural
concept in the economy, which is getting far
beyond the regime change away from the barcode . - RFID-Systems will continue to rapidly gain
importance.
