Wal-Mart Testing New “Scan & Go” iPhone Checkouts
I'm on the fence with technology sometimes; it can be great and time saving but it can also put people out of jobs. Take for example this new idea that Wal-Mart is trying in about 200 of it's more than 4000 stores. It's called Scan & Go and it allows you to use your iPhone to scan your purchases as you go and simply pay when you leave. However, I have a feeling that it will eliminate peoples jobs too.
