Reminds me of people who send scripts to sitcoms then complain they've been "ripped off" when a similar storyline emerges. Considering there are something like 6 or 7 unique sitcom plots and only so many possible pairings, its pretty obvious that "invention" here is non-existent. Oh you also wanted Rachel and Ross to get together? You don't say.
We've probably been talking about RFID as people tracker for almost 20 years. Personally, I'm really getting sick of the whole "they stole my idea" bullshit from young entrepreneurs. You aren't as clever as you think.
