Sony is finally finding a use for the fingerprint reader. When I worked for Accenture Sony was one of my clients. We worked with them to market their fingerprinting technology -- P.U.P.P.Y. -- to entertainment companies as a way to provide added privacy, security, and flexibility to information and services. There just wasn't a market for it at the time. I find it interesting that they are bundling it with other technologies to get it on the market.
