Every loyalty card swipe builds a profile of your habits.
The grocery store knows what you eat, the pharmacy knows what prescriptions you fill, the gas station knows where you drive. That data gets sold to brokers who correlate it with everything else they have on you.
The points are worth pennies. The purchase history is worth considerably more — to them.
Pay cash without a loyalty card and you're invisible to the data collection. If you want discounts without surveillance, some people use fake names and burner phone numbers for loyalty accounts, or share cards with friends to muddy the data.
