Mobile phone adoption continues to grow. By 2010, it is expected that there will be four billion mobile phones worldwide. In many developed countries, mobile phone penetration is well above 90 per cent, so saying 'everyone has a mobile phone' is very close to reality. In March of this year, Newsweek quoted ABI research as estimating a total of 1.6 billion in sales for 2009

History and Figures

According to a 2007 GS1 white paper, over the last 10 years mobile phones have changed the way that we live and work. What is the nature of this change? On the one hand, it's a change in personal freedom. The mobile phone seems to give us more power as individuals to do what we want and be who we want to be. Many people consider mobile phones as extensions of themselves. This is shown by the wide variety of mobile phones available and the myriad ways of transforming each phone into a truly personal device. There are currently over three billion mobile phones worldwide (Informa, Nov 2007). How can we make sense of this huge figure? It means that approximately 40 per cent of the world's population currently carries a mobile phone.
