Probably different models for different sets. The set I work with are purely wifi. They have a light on them to blink is the only extra thing they do

IR on them does sound stupid though, in a store environment that can be blocked rather easily

No they are wifi controlled

It kinda understands context.

An image generator makes an image of static similar to like a TV does with bad signal. The Ai looks atthe static and sees shapes in it. The prompt influences what it’s trying to “see”. It starts filling in the static to a full image, it does this in steps, more steps generally means a better quality image.

Also to say a LLM is a Large Language Model and is different from an image generator, though the proccess for them is very similar.

NFC or something to that effect can be forced"on" with their special charging connection… Or something like that

Would be horrible for data rates but it could be done

Yes, much more staff is hired for online shopping

However funny enough some store increased the hours they had for the front end, I worked for a Walmart that did a conversation and they added like 400 hours to the schedule for monitoring and running the registers. Biggest thing is now they can have 20 registers open and pay for 4 cashiers, before they would have just only had the 3 cashiers and 3 registers. So I would not say the self checkout took jobs, it changed how the job is done

Ist shopping on the sales floor free labor. Back when you would hand your shopping list to a worker and the would give you all your stuff. (funny enough online pickup has kinda brought that back). Things change over time
