That is greatness of technology... but some cunning people in government and in business will use these information for their own selfish agenda.. to manipulate government, to do business in unfair way... and these data may end in wrong hand too... more people information is store anywhere.. in government or elsewhere more restricted life become..
Look at some greedy people and nation.. they talk about free business and trade.. yet they try to stop or monitor every movement of human (being)traffice.
Are we moving ahead or backward...
