Why your grocery loyalty card is actually a trap #Privacy #Data #Shopping
The short version: Mading Thok exposes how Maryland's new surveillance-pricing ban exempts the loyalty-card data pipeline that makes personalized pricing possible in the first place.
Our Take
Credit to Mading Thok for catching the loophole buried in Maryland's headline-grabbing law: banning "surveillance pricing" while leaving loyalty programs and subscription tiers untouched doesn't stop the practice, it just relabels it. Those loyalty cards are the data collection mechanism. Every swipe feeds a profile of what you buy, when, and how price-sensitive you are, and that profile can be monetized or weaponized long after the receipt prints.
This is the same pattern we track with license plate readers. Lawmakers pass something that sounds like a privacy win, but the systems doing the actual surveillance keep running because the data pipeline was never the target, only one visible symptom of it. Flock Safety's ALPR network operates on the same logic: a tool marketed as convenience or safety that quietly builds a surveillance infrastructure most people never consented to and can't opt out of.
With 40+ similar pricing bills moving through 24+ state legislatures, the fight over who owns your data, shopping habits, driving patterns, location history, is only getting bigger. If you want to see how that surveillance infrastructure looks in your own neighborhood, check our camera map, and if you're ready to push back on the hardware end of this problem, our take-action guide is a good place to start.
