I love the Walmart checkout machines. They suffered initially from poor software. The update made in the last 4 months or so is 100x better.

I see two frequent problems.

The first is people with a full cart of items. Without the lazy susan of bags, scanning and bagging takes a long time. Not to mention checkers presumably have some training regarding grouping like items and other tricks of the trade Walmart has gleaned over the billions of transactions in their history.

The second is people that are not confident using the software - I hate to generalize, but usually it's older people. Someone unfamiliar or inefficient with the software can slow down the customer flow significantly, even if their cart size is small.

I love it not only because as a millennial that works in software, using the self check and adapting to unfamiliar situations comes easier to me, but also I rarely check out with more than 5-10 items because I go shopping 3-5 times per week rather than once per week.

RFID resolves this and other problems including inventory and theft. Even if you had to do this via visual inspection its still very possible.(http://mentalfloss.com/article/501060/man-buys-two-metric-to...)

I thought Walmart dictated to their suppliers that every item had to have an rfid chip in it, and this was years ago. Perhaps having one on every single item was cost prohibitive.
