Some Walmart employees say customers are getting hostile at self-checkout — and they blame anti-theft tech

This is a most excellent place for technology news and articles.
In Sweden we usually have a self-checkout alternative where you acquire a wireless scanner when walking in, scanning when picking from shelves and put it directly in shopping bags.
At checkout, you just pay and walk out. There is random controls, where an employee will check like 5 randomly chosen things from the bags. This is seldom though, like once every three/four months or something.
Makes for very quick checkout.
