The Cell Phone as Tracking Device
Given incentives like product discounts, consumers are proving eager to hand over mobile phone data to businesses that want to track their movements.
New services are popping up that track people in real time to give businesses a more detailed picture of consumer habits than ever before. The new tracking services go beyond location-based apps such as Foursquare, which require users to actively check in. Rather, these startups connect the dots of where you go without your doing anything at all. In the past, this kind of location data could be obtained only by asking or paying consumers to fill out surveys. Even then, people might not remember exactly where they went after shopping at Target, or they might give the answers that they thought the questioner wanted to hear.
