Yep. The goal 10 years ago was to come up with a 10 cent RFID tag, that was the price point where Walmart said they would go to 100% RFID and be able to pay for it by eliminating other cost and labor. That cost point may have shifted by now, and it’s a bit of a dilemma as to get to the lowest cost, RFID manufacturers need to have the super-high volume that a Walmart could provide.
Just like the self-ordering terminals at McDonalds, it will come, it’s just a matter of time.
