Credit card companies are subject to stringent privacy and data protection requirements, but they still have access to your transaction history. Although credit card issuers gather and retain information about your purchasing patterns for a variety of uses, including managing your account and preventing fraud, it is not customary for them to sell your purchase history to advertising directly.

Credit card companies may have partnerships with other businesses, including data analytics companies, that offer insights into consumer spending trends. Advertisers may find these companies' analysis of anonymized and aggregated data useful in spotting patterns and consumer behaviour. Usually, the supplied data has been anonymised and devoid of any personally identifiable information, however with so much information out there about us, it's probably not that hard to join dots together.

Ever Feel Like "They" Are Watching and Listening To EVERYTHING?

Apps on your phone collect a lot of data about you, your demographics, your location, other apps, browsing history, contacts and so on. Your phone also has a unique advertising ID.

Data aggregators pay a lot of money to pull in as much data as they can from every available source, including the companies that make the apps you interact with. When you buy something, the transaction is part of your credit card history, and the sale is recorded in the merchant's system. The email you used to sign up to the merchant's website, or loyalty card program, can be used to link to your bank, and your location history to a brick-and-mortar store. Your location is also matched with other advertising IDs at the same location, and over time they can build up a picture of who you regularly associate with. By cross-referencing your interests, browsing history and purchases along with who you are in proximity to, they can target adverts to you based on your interests or those of the people with whom you most frequently are in proximity. How is this legal? Well, your advertising ID is not considered personally identifiable on its own, it's just a tracking cookie, but in aggregate, it does uniquely identify you.
