My local supermarket put little lights in all of their price tags for some reason (???) which is a super fun shopping experience when you have the attention span of a goldfish.

@moiety thanks only took me 40 hours of editing. 😅

@Gina @moiety

sounds like the kind of synthpop instrumental track from an NL pirate radio station 😆

@Gina I think it's because the price tags are digital and controlled by a computer brain somewhere behind the scenes.

I've been picking up something off the shelf before and the price has changed.

I presume the blinky lights, like a smoke detector, mean that it's still working.

@matt @Gina That will be it. All those price tags seem to be reprogrammable E-INK displays.

@matt the future dystopia:

When you pick up an item you get a different price than me. The prices are all personalised just for you, decided by an algorithm. It knows how much money you have and adjust accordingly to maximize profit.

It just knows that you really really need to buy a thing today, boom double price.

Normal digital price tags like these are cool though.

@JohanEmpa Here's a YouTube video about it. And they talk about the dynamic pricing - how it can change during peak hours.

@matt love it - not. There must be some supervillain somewhere that just comes up with all this new tech. 🤮

@matt @JohanEmpa Coming to a store near you: price tags that react to the proximity of your phone and adjust themselves to just above what you can currently afford.

@JohanEmpa @matt I wonder if the feature of paper or electronic price tags is generic enough for Openstreetmap to include it as an attribute on retail locations.

@clh3 @JohanEmpa @matt wait how would that work? As in, what would be the use?

@Gina @clh3 @JohanEmpa I guess then you can use OpenStreetMap to see which of your local supermarkets use “dynamic pricing” or not.

But then, any supermarkets can change the price day to day and i probably wouldn’t notice.

@matt @Gina @JohanEmpa

Admittedly, the level of detail for price tags on shelves, tables, and coolers is more of an indoor mapping exercise.

But one use could be that price tags "play an important role in defining what a particular site or area really looks like," if I may borrow that reasoning from .

For example, there's the animated=digital_prices tag used to tag the advertising signs and kiosks outside gas stations.

@matt @Gina

just had a look at how they work, there is a Bluetooth transmitter put within 500m^2 of the tags that updates them, so it would make sense the LEDs are watchdogs to alert to a tag that has crashed or is otherwise defective (and therefore wouldn't pick up a price change..)

@vfrmedia @matt @Gina Mediamarkt has this system for years now.

At least I don't think that prizes are personalized (based on your PII, etc. Would that even be legal?).

I did work for Albert Heijn years ago via my employer. In their HQ they have this concept store, where they demo'd this already.

The counters also had positional LED lighting, so each package in the store would be lit with the exact color of light to make the product look most attractive and enticing. Cool, but nasty too.

@humanetech @matt @Gina

I think changing the prices would definitely be against GDPR and probably other domestic law across Europe, and not really practical anyway (as other people could be standing close to the person with the targeted prices).

I remember seeing Philips selling lamps for food displays etc for improved aesthetics back in the 80s, but dynamic control of the lighting is certainly a new thing (its not however something I've seen in the UK yet)

@humanetech @vfrmedia @Gina I don’t think it’s to personalise prices to an individual - just updating the price on the shelf. There could be 20 people in the store at once and that price has got to stick when you get to the cash out.

The intent is to boost to certain items at certain times of the day.

Pre-made sandwiches sell at lunch time? Boost the price by $0.10 between 11:30 and 2pm. Not too noticeable for the individual, but across the country you could be a few thousand dollars up.


> The intent is to boost to certain items at certain times of the day.

And possibly to get rid of some more personnel, or pay less hours.. saves a lot of time not placing all those price cards every day.

@vfrmedia @Gina

@humanetech @matt @Gina

I've heard that petrol prices in Germany change depending on the time of day (not something I've encountered in the UK); which suggests that this kind of dynamic pricing is at least tolerated there

@Gina: Whoa, this is distracting. Shopping is already "fun" when you anxious in tight or crowded spaces. This would force me to buy my food online.

I noticed this today as well!

Also, I see you put your editing skills at work 😏

@Gina you had fun with editing lol

the blink is probably because price tags are in a “listening” state, ready to update or just low battery

@duponin I'm just amazed that I never realized that price tags are little monitors nowadays.

@Gina back a decade it was more obvious, it was seven segments numbers but now since it uses e-ink it’s way more discreet

and yes those are totally hackable ✅

@Gina There's a store here that has those anti-theft devices on expensive clothing items, and for some reason they come with a little solenoid that clicks every few seconds. With hundreds of items, it sounds like a forest of crickets.

@Gina Interesting. Wonder if that will come here to the U.S.

Judged by your profile picture, you don't look fishy...

Nice music 😄

What's odd, the large chains supermarkets still use paper/cardboard price tags around here, while some smaller independant stores (mostly the "bio" oriented) have these e-ink price displays.

@Gina Can I ask if you've seen these in other supermarkets or just this one? Can't say I've seen them here in the UK yet.

@Gina I have no idea, but gosh that’s pretty!
