A new version of the smarter shopping cart will be coming to a nearby market this fall. Thanks to various partnerships and technological innovations of Instacart Inc., the latest embodiment of what the company calls Caper Carts will be able to track purchases while shoppers navigate through the aisles. The goal is to make it easier for shoppers to skip the checkout lines.

But it’s a tough reach, given the complexities of the retail channel and how the items will be scanned and tracked. If it works, it could be a major time saver. If it stumbles, it could be another example of bad user interface technology that is presently in most grocery and other retail chains: automated checkout scanning lanes. I write about it for SiliconANGLE today here.
