Walmart is Testing an All-Self-Checkout Supercenter in Plano, Texas

Walmart's self-serve system(s) appear to be the most reliable of the stores that we shop. B/C scanners for big stuff are wireless, keypads and touchscreens are functional and responsive, the scales read produce very fast and are more accurate than the local Vons/Stators/Ralphs (I have done several 'calibration' runs at all of the local markets), system latency is the least of all other stores, and when I screw up, an 'associate' quickly arrives to render a fix.

And that is about the only good experience to be had at walmart.

Two months ago I went to the Walmart in Cortland, NY and they had a self-check system I could only describe as "awesome".

I'm sure there was a staffed cash register somewhere but I couldn't see it.

The next week I saw the staff in Ithaca, NY struggling with the same system, but the week after that they had it running smoothly.

It made the checkout experience at the Union Square (NY, NY) whole foods look like it needed a "digital transformation".
