Yet I get vouchers from the supermarket tailored to correspond to items
I've already purchased from there. I doubt anyone's picking over the data
individually more a case of X purchases within Y days of product type Z
all ranked with the top five being assigned corresponding vouchers.
It's also something to remember that such stores are branching out into
other areas such as insurance etc. and that some cards can be used in many
participating stores. In theory if I used a store card everywhere I could
the company could know what I eat and how often, what type of clothes I
buy, the books I read, the movies I watch, where and how often I buy
petrol. Sure it's all automated until someone in the government decides
they want to know more about a suspicious individual's habits.

At the very least it could reveal your work hours.
