Spotting a strange white box under your Walmart cart? It’s not tracking your groceries, but it is tracking the cart itself. Walmart’s rolling out GPS devices to keep tabs on their carts—likely to prevent theft and cut down on abandoned carts, which cost stores millions each year. Some folks online worry it’s about tracking shoppers, but the tech is just for the carts (for now). With stores testing even smarter carts elsewhere, it’s clear shopping is getting a tech upgrade. How do you feel about more surveillance in your everyday errands? #Food #Walmart #ShoppingTech
