Yesterday I got a statement from my credit-card company. It was a transaction summary for 2005; I've never seen this sort of thing before. The front page informed me that last year I spent $X on food, $Y on entertainment, $Z on professional services, and so on for about 15 broad categories. That's the sort of thing that could be useful if you don't think about it -- but I'm the kind of person who thinks about it.

I'm not sure which possibility is more disturbing: that they are making inferences based on who the payee is (Giant Eagle sounds like groceries, etc), or that the merchants are providing the credit-card companies with categories for the transactions.

My record-keeping is not thorough enough for me to figure out which is more likely on my own. Perhaps I will ask them.

When I use a credit card I fully expect that the particulars of the transaction -- date, amount, and merchant -- are not private and might be mined. If it's really important to me, I pay cash. But I do not expect a description, even a high-level one, of the goods or services purchased to be part of that record.

I think each credit card account is linked to a specific category. I don't think the drug store/ retail distinction is made- AMEX def. doesn't do it- they just list under general retail/merchandaise, and include grocery stores in with department stores or drug stores.

Not sure how the VISA system does it or Mastercard. It's all about the classification on the store, not the purchase. They use it to determine the rate involved to the store, and other things..

*THIS* one I don't mind them having so much. I don't think they get anything past what's reported on the statement, though, which isn't so bad.

However, Amex gets more details on plane trips and such from some vendors.. which is just a bit weird to see on my statement- it says flight to XYZ Place on it :_)


I do find these annual statements handy, for taxes. It's also really strange to see how *much* we spend!

No- I think it's more like all Duane Reids = Drugstore = Retail. All Texaco pumps = Gas/Auto, inside store = Retail. I think the categories aren't inferred, it's determined when you sign up as a merchant. And in some ways,

The rest of that already happens on some levels with those loyalty programs. The tag you get from Giant Eagle... that's tracking exact purchases. They probably don't do it on the pharmacy side, since that would be more problematic with HIPPA, but everything else... it's a free game.

I think this is less sinister than what they do with the loyalty card programs... There isn't that much information sent via the credit card terminals right now to VISA, so you're probably safe on that front... for now.
