Weakness of bar code : Limit of supply chain speed : product by product No global vision
Apparition of RFID : identification method Composed of RFID readers and tags Used in many domains
RFID advantages Retrieve data remotely (up to hundred of meters) Can read multiple tags simultaneously
RFID weakness Price Air collision

RFID imposes many needs and constraints
Devices heterogeneity
Read/Write to a tag
Manage gathered data
Air collision
A set up of external sensors to trigger readers
False positive, false negative

Open source RFID software platform Last release in July 2008 FOSSTRAK project provides the core components
of many RFID system deployments Composed of 3 modules :
Each module is based on EPCGlobal standard and can be used independently

Advantages Hide the complexity and the heterogeneity of the
hardware part Avoid false positive and false negative Get intelligible data Ideal to start a business aplication
Problems RFID problems Gates issues Missing information
11AUBERT - POCCIOLI - SCHAMBACHER
Two kinds : Full middleware Part of middleware
Full : Singularity (J2EE)
Part : RIFIDI (Java) LLRP Toolkit (C/C++/C#/Java…)
None is as complete as Fosstrak
12AUBERT - POCCIOLI - SCHAMBACHER
FOSSTRAK seems to be a good implementation Composed of 3 parts Reusable
Major problems are constants of RFID tags
A great way to make developer focus on business routine and not on RFID technology
Nice start point to work on RFID issues
