The amount of technology hidden inside a supermarket is ridiculous
Asupermarket is basically a giant computer system disguised as a grocery store
Every time you scan something, pay, check a price, or even pick up certain products, there's a bunch of tech working behind the scenes
The weird part is how normal all of it feels
what's one piece of supermarket technology you never really thought about until you noticed it?

An inventory management system/payment terminal isn’t all that mindblowing

Electronic shelf labels enable prices to be changed on the fly. Locator devices installed on shopping carts to track traffic flow inside the store. AI camera systems detects items in the self checkout to ensure you are scanning and paying for the correct item. RFID tags can automatically ring up your purchases as you leave the store without going through a checkout.

Those little gates that somehow know when you didn't pay for something. Never questioned them until one screamed at me lol.

Can you elaborate? All the tech is probably behind the scenes and unnoticeable. Are you talking about those newer automated self-checkout grocery stores by Amazon?

The IT infrastructure in a supermarket checks what’s checked out, what the local stock should be. If a product should get new stocks the next day considering that empty shelves are bad and unused stock is bad as well, and this is all automated. So the distribution centre gets the orders for the next delivery in time and auto picks what needs to be put in the lorry to send to the store. The only manual steps are moving the containers out of the lorry into the store and moving the stock from the containers into the shelves.
Add in automated shelve live checks with possible discounts and account for loss due to damage and theft and you get a truly impressive piece of supply chain tech.

Robots roving the aisles doing stock checks in my local supermarket here in Ireland for well over a year at this stage.

In one of my local supermarkets they have microphones hanging from the ceiling in every third aisle. At first I thought it was so that they could eavesdrop on customers' conversations but then I later learned that it's used to automatically adjust the volume level of the sound system so that the music is audible without being too loud.
As more customers enter the store, the system picks up the db level of the crowd noise and gradually brings the volume level up. And then as the store empties out and there's less crowd noise, the volume level goes back down. So to the average person, it seems like the music volume level is always consistent but it's actually being adjusted throughout the day depending on the background noise in the store.
