Walmart got into problems with this in the past using this technology in secret without informing the public so they had to stop as it is a violation of our right to privacy.
Today there are tons of companies that want to jump on the data commodification gravy train and several start-ups writing software and making equipment are looking to cash in. All they need is a way for Big Business to argue the customers have given their implied consent by not protesting and suing them over this intrusion. I believe this is why Walmart is beta-testing this system in my poor neighborhood.
