In order to connect to Facebook, you would first need to develop an interface that would tie a person’s login information with his or her ID. For example, let’s say I were to register for your social-networking application. It would store my Facebook username and password securely, and link that information to a serial number in my RFID tag.
Any time I scanned my badge, the software application would go to Facebook and enter my username and password. The software would then usually check me in with Facebook, or indicate I “like” something. You would probably have to work with Facebook on this application program interface (API) in order to automatically “like” something.
