I was checking the other day the download numbers of LTKJava, the Java implementation of a Codec for the LLRP protocol which the Fosstrak team contributed to the LLRP toolkit project. The Java implementation has been downloaded more than 600 times since we released the latest version at the end of July. The usage of LTKJava by major reader vendors and reader middleware such as Intermec and OatSystems underlines the contribution open source software can make to the field of RFID and the adoption of standardized protocols.
At Fosstrak, we are using LTKJava in our Fosstrak LLRP Commander, a tool to control and manage RFID readers via LLRP.
