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

Reader #47 Reader #63 Tag #12 Tag #12 detected by Reader #47 Tag #12 detected by Reader #63 3 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

Reader #47 Reader #63 Tag #12 Cartridge appears in warehouse Cartridge moves from warehouse to dock n° 3 Tag #57 Printer present in warehouse Not a Tag False negative suppressed False positive suppressed 9 AUBERT - POCCIOLI - SCHAMBACHER
10
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
11
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
12
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
13
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
