Don’t ask me why it took the better part of a week for me to notice that there was an article about keeping track of herds of cattle with a system comprised of Bluetoooh (that was a typo, but I’m gonna roll with it), RFID tags, and special Palm software. There’s not a ton of detail in the BargainPDA write-up, but there is a handy software flowchart on developer WYTrax’s site.
