I did something this week that I don't often do: I shopped for (non-grocery) things in person. Like, in a physical store. So I recognize that this isn’t entirely bleeding edge. Still, I am thoroughly impressed by the self-checkout process at Uniqlo.
All of their items now include RFID tags , which means you don’t need to scan anything. You just place your basket or items down, and then everything shows up automatically on the screen. Done. The most frictionless checkout that I have ever experienced.
My understanding is that this was done more for supply chain management and that it is now possible because the cost of these tags have come down to something like a few cents per unit; but the added benefit is that they have greatly improved checkout throughput and the overall experience.
This has been a part of the promise of RFID tags for many years. And this week I experienced it IRL for the first time. It was awesome. Now I hope this same experience comes to grocery stores in the near future.
