The Secret Life of Credit Card Data

'Despite a federal privacy law covering our cards, a single swipe hands your data over to at least a half dozen different types of companies — retailers like Target, marketers, even hedge funds — all of whom are making big profits off that information. It’s all part of a sprawling and largely unregulated credit card-data economy. Geoffrey Fowler, a tech columnist with the Washington Post, joined  The Takeaway to break down what is being shared and how it's being used. Fowler recently conducted an experiment where he used two different credit cards to buy two bananas at Target and then tracked where that information went.'
