In accordance to this theory, every individual in the society, regardless of their social station in life, have a positive contribution to life and also depends on all the other people to survive. This theory can be seen at work with most of the technologies advertised by AT&T in the video clip. One such technology is the smartcard technology which allows people to access their money anywhere in the world. In the advertisement (AT&T 0 min 37 sec), it says “have you ever paid a toll without having to slow down and then shows an individual swipe a Smartcard?” This technology is a network of money transfer services and the only way it can work is when used by many people of all works. Based on the fact that smartcard technology depends on as many people as possible using it to be effective, a sociologists who subscribes to the functionalist theory would argue that the technology explains functionalist theory. It is also good to note that apart from the smartcard depending on the many people of all walks of life using it, it also depends on so many technologies which are not directly related to banking. These many technologies such as internet, satellite and computers, work together to enable the smartcard technology and therefore this is also supportive of the functionalist theory. All these technologies are also developed by different people most of whom don’t even know each other.
