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

hardware part


Avoid false positive and false negative

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

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
