Your credit card mostly on gets merchant name and total purchase value, so the uses are fairly niche. It’s more likely merchants themselves indirectly selling your purchase data.
You can sometimes click the small blue triangle in the corner of an ad (called adchoices) to see how it was targeted.
- chronomex 6y agoOne hundred percent of the time when I've clicked that button, it says "XYZCorp is advertising to people located in the United States", even when the ad is clearly more targeted than that.
- soared 6y agoAh, I wish it was better than that.
- disgruntledphd2 6y agoSo, assuming that this is FB or Goog, then that makes sense. FB certainly encourage advertisers to use broad targeting with conversion optimisation. This means that the audience is 18+ living in USA, but the combination of the targeting plus the optimisation (click and conversion prediction, mostly) means that it seems much more targeted than it is.

- nitrogen 6y agoIf I recall correctly, when I worked on ecommerce payment processing several years ago, the payment processor got a full itemized list for each transaction. Another comment here mentioned airport codes for airfares (https://news.ycombinator.com/item?id=25577366 https://news.ycombinator.com/item?id=25577366).
- soared 6y agoThat was my comment actually. You could be right, as I’ve only used visa data for advertising which was merchant names only. Lots of merchants do sell itemized data though. Stripe/etc definitely get itemized, but credits cards get less as far as I know.
- nitrogen 6y agoThat was my comment actually. Lol, I should probably pay more attention to usernames :) I've worked on the payment processing end, but as I said that was several years ago, as well as on the consumer data end (e.g. using services like Plaid). You could equally be right about what ends up going from Stripe/Braintree/etc to Visa/Mastercard/etc, though comments/links about Level 3 payment data make me think that the itemized level of detail will increase in usage, and also as you say transactional data is certainly bought and sold outside of the payment networks.
