I'm still pissed about how accepted surveillance capitalism is. In Germany there is this "payback" system where you identify at the checkout in shops and collect points you can turn into free shit. I'm still saying no every time the cashier asks me if I'm interested. I don't want anyone to datamine my shopping habits.

@Gargron but don't you -want- to give up all your privacy in exchange for more relevant advertisement?! owo

@Gargron Don't worry, they'll still data mine you regardless of consent.

@Gargron Skip the store cards at grocery stores in the US (at least around here in Seattle) and you pay more. Many advertised prices are only for people with store cards.

@Gargron I agree.

It's a common practice to share the numbers for the store cards with friends, so they don't have to mess with getting a card and store data mining is at least a bit messed up ^_^

@Gargron I still laugh at how many times I get coupons from the store for feminine hygiene products.

@gargron @randomgeek This is also why I don't shop at Kroger / CVS. They do this shit all the time.

At least Meijer (local supermarket) doesn't pull that, and does discounts on top of the "MPerks" program.

@Gargron here in Rio (and also in São Paulo) we have a similar system where you can opt-in to have your CPF (one of the many nation wide identification numbers) in the receipt. This gets you points which become rebates in the IRS. The idea is not to datamine the client but by adding your CPF there, you receive an instant email with the NF-e (electronic receipt) of the purchase from the government servers, this forces business to actually pay taxes as they can't hide the purchase

@Gargron if people like us tell others what the disadvantages are behind such disingenuous systems then it'll change

@gargron there are more methods shops use to detect & record your habits, such as identifying your smartphone unless its WIFI is turned off

@mcscx that's why i always turn my wifi off before going outside

yeah i am aware of that technique

@Gargron Chaos Computer Club had a Payback card-sharing scheme - multiple people sharing those cards for the benefit of the organization

@gargron Same system in Britain ('nectar points' et al), but over the last couple of years shops have started making cashiers directly demand your name and email address. (Often "So that we can email you a receipt" or "To warn you if the product you're buying gets recalled"). I refuse but, paying by card, they easily have the data to track and profile my shopping habits whatever I do. Why practice surveillance capitalism when you can get the same data through plain surveillance?

@Gargron this has been around for ages, in so many ways. Unfortunately as someone whose has very little money a lot of the time, it kinda becomes a necessary evil... 😕

@gargron our local supermarket chain has one of these programs. We opted in because they're already tracking is whether we want to or not. So might as well get some payback for being collected.

@Gargron I immediately realized what 'loyalty' cards were 1st time I encountered them. I began to rant, but a friend who was a cashier there rushed over to hush me up.. Turns out you can get anonymous cards. Mine is connected to a children's hospital. They routinely clear off the pointsand I get the proper price without the cardless 'penalty mark-up'.

@Gargron
I live in Germany, too, and also refuse to have a Payback card and everything that goes along with it.
And not only because I'm not into revenge all that much... (I mean, who invents the names for these things??), but because of the data they gather.

@Gargron There's a "rewards" program like that at a gas station chain here. I participate, bc they only need an email address, and I give no other personal info. I can build up points, turn them in for big payout, then throw it away and get another card. It's still data collection, but I can be sure it's anonymized.

@Gargron i met worse at airports, "get our credit card, you'll get back each month X amount of your _grocery_shopping_"
…so, how do they know whether your shopping for groceries or other ;))) (theoretical question). best (in regards to privacy: worst) and cheapest market research tool is when they have direct access to your wallet…

@Gargron Are you paying with cash ? 'cause if you're using any sort of credit or debit card, someone is already datamining your shopping habits.

@Gargron @Keltounet even without payback systems or the cards that poor cashiers spend their days pushing, companies (the like of Nielsen) receive full check-out info with cart composition / tickets from supermarkets. They can easily deduce households composition, income, etc, from what you buy, I'm pretty sure they can very easily identify individuals based on their shopping habits. Those programs are just incitement to provide them an unique identifier.

@Gargron Same issue with shops in the US. At Safeway, they give "discounted" prices if you identify yourself, but actually it's punitive (increased) pricing for those who don't identify.

@Gargron the first thing that convinced me I actually knew German was when I heard a totally nonsensical phrase from the checkout lady—"Sammelst du Herzen?"—and I was able to parse it into words

@Gargron in the US, you can look up your "loyalty card" with a phone number. At every store I use 867-5309 (which is a phone number from a famous song, if you don't know it) and somebody has ALWAYS filled out the paperwork for it

@xor @Gargron I usually give 202-456-1414. Everyone know's Jenny and knows it's bullshit. Most don't recognize the WhiteHouse switchboard. :-)
