A NaN spotted in the wild.
THE PRICE TAGS ARE RUNNING JAVASCRIPT!!
Oh fucking joyous, automatic surge pricing labels have finally hit the UK, can’t wait for it to be tied to your wifi shadow and device biometrics so that supermarkets can charge people more for daily goods than their neighbours due to their credit/social/political standing.
I mean “Haha that means it’s free, right? Lol.”
Sorry, zero is a number, so it can’t be free. One soul please, or alternatively one upper and one lower limb.
“I have five pounds. Is that enough?”
“No.”
“It costs more than five pounds?”
“No.”
“How much do I have to pay?”
“This is NaN pounds.”
“That means it costs more than five pounds?”
“No.”
“It costs less than five pounds?”
“No.”
“Exactly five pounds?”
“No.”
leaves the shop
(Remember, comparison with NaN is always false)
That’ll be one [object Object].
With my [Object object] please 😁
IT DOESN’T NEED TO BE COMPUTER! IT IS A PRICE TAG! THERE IS NO REASON IT SHOULD BE ABLE TO RUN DOOM!
Technically, these digital tags are being developed to automatically update price from a database, so there is a computer somewhere.
I think they’re just e-reader technology that accepts input by RF or something. Probably has an RFID on it, so a control node just (1) scans the RFID, (2) looks up price of product for that RFID, (3) send signal back to update the display. Meaning, someone still has to walk up to the price tag in order to update it.
My worry is live updates to pricing tags based on things like facial / behavioral recognition from the cameras in the ceiling.
I’ve looked at these things. I don’t see any modules for wireless communication over lan, Bluetooth, or anything like that.
See that window in the top left? It’s a combination photovoltaic cell and IR receiver, so the tag can be powered indefinitely from the shop lights and they can use ceiling-mounted IR blasters to update them. There’s no return path so the blasters just repeatedly transmit the entire inventory and price list, over and over.
Is it garlic NaN?
Do you accept ⯎̷̨̩̯͎͕̮͎͈̞͙̠̽̈́͂͊͗̆͗̒̓͠͠ͅ⥢̴̛̠̩͑̂ⵅ̴̨̨͍͎̄̌͂̐͗͂̄̓́̽͊͐̆̍͘⊣̸̢͙͈̠̗̬͎͎̗̖̓͂͌͆͑̔̔ͅⅆ̸̧̜̲̙̱̱̙̦̗̺́͗◰̷̛͙͓̹͕̯̘̝̌̈́̍͐̌͘̕̕⽅̶̠͔̼̙̠̻̖͕̻͔̗͗̎́̈́̃̀̈́̽̽̅͌͜⸦̴͎͚̦͖̜̞͙̲̑̕?
currencies beyond my comprehension, sorry I can’t pay.
Plot twist: it’s accurate, because the price is not a number but in fact your very soul.
The folks who said barcodes were the mark of the beast were so close!
Sounds expensive. Most nans weight a lot of pounds.
NaN is still mad about the new twenty pence being so small and fiddly.
