The link below talks about firms (using one in Canada as an example) being able to track your location and movements through your mobile phone. Using this, producers will be able to market their goods/services to cater for specific consumer tastes, rather than “guessing”. The possible private benefits are massive, BUT ( and this is a big but) what happens if they start selling this information? Do the costs outweigh the benefits? Putting that aside, do you really want random people to know what you have for breakfast, where you work or even where you live?
