Yeah, I’m not actually that worried. I’ve seen these in use at hardware stores for quite a while now. It’s just useful to assume that Walmart is planning to fuck you over. That’s a good point with BT though, many of the kind of microcontrollers that would be used for this sort of thing offer BT connectivity as well.
My government teacher in high school took our class to a Herman Cain rally. It was… interesting. Towards the end of his campaign, so it was in a BBQ restaurant that had a stage for bands and maybe 50 people were there total. I don’t remember much about it, other than it was hard to hear because we were in a restaurant that was still playing music in the other room. I believe you’ll have a very different experience tonight lol
