MasterCard Is Selling Your Data Just in Time for the Holidays
Credit card companies make money by taking a cut every time you swipe your plastic at the checkout counter. Now MasterCard has found a way to make those swipes pay over and over again.
As the Financial Times first reported, MasterCard is packaging its transaction data — your transaction data — and selling it to advertisers. The story was based on an apparently confidential pitch MasterCard made to potential clients. Not too confidential, because we found a copy by googling it.
