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.
From an employee I talked to it's because they have a specific contract with the payment processor and it requires using specific payment devices that are covered in the contract and they don't want off it for as long as possible because it gives them preferential fees.
So until the cost of business lost is enough to cover increased payment processing fees, don't expect to see tap to pay.
It definitely cost them my business at least twice when I forgot my wallet and remembered they don't take NFC so I went across the street to target.
Why don't you just go to Target first? You can get all your crap ahead of time and just pickup the order. Their prices are super low to compete with Walmart and they price match. Right now it's basically Walmart with better customers.
The main* reason why people go to Target is because they're willing to spend a bit more to not have to shop at Walmart. Not everyone can afford that luxury.
