Introducing accurate facial recognition into the mix potentially removes the need for you to tell Facebook (or a future Facebook connected site or app) who you are before your data is shared and your experience modified. All you will need to do now is show up and let a camera see you long enough to capture a reasonably clear image of your face. From there you will be identified, placed into a particular context and things will happen. As a brand, there are some interesting opportunities. Imagine your guests arrive at your event and, instead of relying on guests to manually check in, a webcam at the door connected to your Facebook Page recognises the guests as they arrive and posts an update in your stream sharing their arrival. This isn't happening yet but it is very possible.
