 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 2 AUBERT - POCCIOLI - SCHAMBACHER

 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 4 AUBERT - POCCIOLI - SCHAMBACHER

 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 AUBERT - POCCIOLI - SCHAMBACHER 8 RFID readers Reader modules

 Lots of logistical domains  Warehouses  Big or little shops  Mailing companies (see colissimo in France)  Gates monitoring  RFID tags at Polytech’Nice  Marina surveillance 10 AUBERT - POCCIOLI - SCHAMBACHER

 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 11 AUBERT - 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 12 AUBERT - 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 13 AUBERT - POCCIOLI - SCHAMBACHER
