Google Tracks Your Credit Card Purchases

Mastercard sells your credit card purchase information to Google.

Google and Mastercard struck a secret deal worth around $10m; where Google gets access to the shopping data of Mastercard customers, so they can measure the impact of online ads. Google announced the ‘Store Sales Measurement‘ tool last year describing it as a technology that would let advertisers’ link online ads with purchases that consumers make offline in brick-and-mortar stores. 

Most of the two billion Mastercard holders aren’t aware of this behind-the-scenes tracking. That’s because the companies never told the public about the arrangement.

Obviously this raises a phenomenal amount of privacy concerns. Customers would not have been aware of this until the news broke this week; and clearly they would not have an option to opt in or out of having their data being used in part of this deal.

Google has approached other payment companies about the program, according to two people familiar with the conversations, but it is not clear if they finalized similar deals. The people asked to not be identified because they were not authorized to speak about the matter. Google confirmed that the service only applies to people who are logged in to one of its accounts and have not opted out of ad tracking.
