What's RFID ?

Radio Frequency IDentification (RFID) is a method of remotely storing and retrieving data using devices called RFID tags or transponders. An RFID tag is a small object, such as an adhesive sticker, that can be attached to or incorporated into a product. RFID tags contain antennas to enable them to receive and respond to radio-frequency queries from an RFID reader or transceiver.

An RFID system may consist of several components: tags, tag readers, edge servers, middleware, and application software. ObjectWeb RFID initiative focuses on open source RFID middleware.

RFID Middleware

According to (Venture Development Corp.), five middleware functions dominated the end user want lists: + Provide a consistent interface for the RFID interrogator infrastructure.
Standard interfaces human, machine, network, application do not exist across various RFID interrogator solutions.

+ Data filtering and transport.
Similar to the lack of standard interfaces, users cite the varied methods used to filter, compile, and route RFID data traffic as a key challenge during the implementation and integration process. Users are looking to RFID middleware to account for these differences, and resolve them in a consistent manner.

+ Manage the RFID reader/interrogator infrastructure.
Key functions cited by users and evaluators included local and remote monitoring, upgradeable software/configuration, and remote power on/off.

+ Support for multiple host platforms requesting RFID data.
The most often cited platform challenges included: warehouse management systems (WMS), order entry/ order management systems (OMS), transportation management systems (TMS), logistics management systems (LMS), supply chain management systems (SCM), and data warehouses.

+ Support for legacy systems.
