In Stores, Secret Surveillance Tracks Your Every Move (nytimes.com) 173

In retail stores, Bluetooth "beacons" are watching you, using hidden technology in your phone. From a report: Imagine you are shopping in your favorite grocery store. As you approach the dairy aisle, you are sent a push notification in your phone: "10 percent off your favorite yogurt! Click here to redeem your coupon." You considered buying yogurt on your last trip to the store, but you decided against it. How did your phone know? Your smartphone was tracking you. The grocery store got your location data and paid a shadowy group of marketers to use that information to target you with ads. Recent reports have noted how companies use data gathered from cell towers, ambient Wi-Fi, and GPS. But the location data industry has a much more precise, and unobtrusive, tool: Bluetooth beacons.

These beacons are small, inobtrusive electronic devices that are hidden throughout the grocery store; an app on your phone that communicates with them informed the company not only that you had entered the building, but that you had lingered for two minutes in front of the low-fat Chobanis. Most location services use cell towers and GPS, but these technologies have limitations. Cell towers have wide coverage, but low location accuracy: An advertiser can think you are in Walgreens, but you're actually in McDonald's next door. GPS, by contrast, can be accurate to a radius of around five meters (16 feet), but it does not work well indoors. Bluetooth beacons, however, can track your location accurately from a range of inches to about 50 meters. They use little energy, and they work well indoors. That has made them popular among companies that want precise tracking inside a store.

        Yep but then he's still just paying retail. He's still winning; it's people buying at the original marked up price that are being taken by the store in the form your vernacular describes.

        • In my example retail price doesn't really exist. Computer picks up that SuperKendall is in the store. He usually buys carrots at around $3 a lb, but he's spent more. So it raises the price to $3.75 a lb. As you go near a coupon pops up, 15% off, so they are now what, $3.19, and you think, oh sweet deal since you buy carrots anyway and you don't look too hard at the price. But the retail is really $2.99 but this place always marks it higher.

        Apparently this is weird behavior, but I know how much things I buy tend to cost. I do a lot of shopping at various stores and the best price on things varies quite a bit.

        If I see onions for $.49/lb I will buy a bunch. A tub of yogurt for $7.50 marked down from $12 will be a hard pass.

        This is part of the bean counters trying to run every system to peak efficiency for their organizations. It causes flash crashes on Wall Street. It cause rumors to flash around the world faster than the speed of truth.

        The problem with this is it leaves systems we rely upon with no hysteresis. Any small jolt can send the system careening into unanticipated and frequently chaotic behavior. Decent engineer designed systems are built to gracefully degrade in adverse conditions. Bean counter designed systems are like dirty snowballs, accumulating offensive behavior that only really gets noticed when the system breaks. The things that cause it to break are like cracks in the system. When the system is run under too much strain, any one can break it wide open.

        "People, especially younger ones, place less and less value on privacy and autonomy.

They will learn the hard way, and take the rest of us with them when it helps generate a dictatorship. China is a good example of what can happen. I hope the people there will get fed up. But then again, when the central system has that much power, is there any hope people can change it?

      Call me a weirdo: but I'm fan of targeted advertising. Why would I be against a system that gives me coupons tailored to things I'm thinking of buying anyway?

      No, that's the wrong type of targeted advertising. Think about it from the store's perspective. If they're giving coupons to people for stuff they already had a high probability of buying, then the store would be losing money. Better not to give them a coupon so they pay full price for stuff they're already going to buy. Coupons only make money for the store if they get a person to buy something they initially weren't going to buy. A coupon sent to a person for something they were going to buy anyway is a money loser for the store.

      The good type of targeted advertising is the kind which notifies you of deals and products which you want, but didn't know about yet. I learned this when I lived for a couple years without a TV. Whenever my friends and I were trying to decide on a movie to watch, I was completely lost. I hadn't seen any of the commercials and trailers, so I had no idea what movies were playing and what they were about. Ads can actually inform you about the choices you have, allowing you to make better purchase selections. In this context, targeted ads are even better because you'll see fewer ads you're not interested in. And (theoretically) you won't see as many repeat ads.

      So coupons for products you're already staring at while in the supermarket are a bad idea for the store. The ratio of people who wouldn've bought it anyway without a coupon, to people who were thinking of buying it but decided not to until your coupon came along, is too high and the coupon ends up costing the store money. Saavy shoppers would get into the habit of pausing in front of everything they need to get, hoping that a coupon for it will arrive on their phone, costing the store even more money. The best coupons (for the store) are the ones which get a person who wasn't going to shop at that store, to shop at that store. Usually they won't just buy the coupon item - they'll grab a few other things as well "since I'm already here." Same way fast food places make most of their money on drinks and fries added on to burger orders.

      • What are you talking about? If you are standing looking at widget X and you get a coupon 20% off of widget X it is going to incentivize you to buy widget X. Plus most of these are manufacturer coupons anyway, not the store. So the coupon is an added incentive to buy widget X over competing widget Y.

      First, coupons are in general a bad idea for the consumer.

      Yes, people like them, but they are bad for you. You like them because you think you are getting a deal. You are not. They raise the price by that amount and offer a coupon. EVERY TIME. It's called Price Discrimination. The idea is to charge every single person the maximum they will pay. So the guy making 100k pays $5 for the ice cream cone, because he will reluctantly pay it, while the the guy making 40k pays only $4 for the same cone.

      So you are actually being forced to do more work, collecting and using the coupon to help the manufacturer sell the wealthy guy the same thing at a higher price.

      Coupons are the worst thing that ever happened to the consumer. It lets a businessman make the poor person do extra work so the business can charge the wealthy guy more money.

      They do NOT save you money.

        No idea what you're talking about here.

        I recently had a child. That child needs formula. The formula he likes/tolerates is (let's say) $30. It's always $30 (at every store, give or take a few dollars).

        I (and everyone else) pays $30... often.

        Sometimes there is a coupon (often through the mail, sometimes in-store) that allows me to purchase the formula for less than $30.

        How exactly is that _not_ saving _me_ money?

        When the coupon is out the price of the good doesn't go up to compensate. It stays right at the price it's always at.

        As for "wealthy" vs "poor"... I make plenty of money and can afford the formula at $30. But that doesn't make me just throw away a coupon that's going to save me money. Often, I see that it's the other way around: people who have money _have it_ because they are good at not spending it frivolously. They look for deals and coupons and think critically about what they need. Coupons often play a role in that.

        • This. Right here. Fried has it 100% correct. If you are willing to jump through hoops to get a better price, then you will come out ahead of the person that doesn't want to expend the extra added effort.

          Because without the coupon, the manufacturer could charge EVERYONE a price somewhere between the regular and coupon price(with same profit) and you would save money on average. Just like health insurance, all that extra paperwork costs money, be it printing and processing coupons or haggling back and forth between the doc and insurance. Nothing is free. Problem is human nature and the store trying to extract the maximum profit. So keep clipping to save a buck.
