week 5- big brother

This weeks lecture on input systems got me thinking to myself: "self, just how can I use RFID tags to better my PPA business?" After some time contemplating I'm still not sure. After all, I'm not necessarily selling or taking in any real physical product. Theoretically I could use them for payroll, giving my PPAs RFID badges and a reader to each client. That way we have an exact measure of the time for which my employees would be paid. But I can't help but think such a system could easily be fudged. Unfortunately, tech like RFID doesn't seem efficient in a service business like mine. At least, not yet. So for the meantime, I'll stick with GPS.
