The funny thing about all of these types of things is that they always mention storing or exchanging data with a central computer. There seems to have been a raft of really bad (and I mean really bad) patents issued for every type of little number or data bit that can be stored on a computer.

Yeah, computers store data. No, you're not a genius for thinking of yet another little thing to put in your computer.

I haven't actually read the patents, but from the overview I would guess that they are completely obvious solutions that patents should never have been granted for.
