I believe Walmart uses RFID extensively in their logistics/distribution pipeline, and they have a lot of control over their suppliers, so I'd assume they would use it in the store if it was viable. https://www.atlasrfidstore.com/rfid-insider/walmart-and-rfid-the-relationship-that-put-rfid-on-the-map https://www.atlasrfidstore.com/rfid-insider/walmart-and-rfid... I'd be interested to know the precise reasons for not using RFID on items though, I suspect it might be something like "tagging $1 items is cost-prohibitive, and the system isn't useful if you don't tag every item".

I'd be more inclined to suspect that the sheer square footage of their stores makes it cost-prohibitive to outfit the space with the sensor infrastructure (comparing to Lululemon, who has much smaller stores). The tags themselves are fractions of a penny (I'm seeing $0.002 on alibaba) and are just applied as stickers, so I don't think that's too much of an issue -- not to mention Walmart probably has the buying power to insist their suppliers pre-tag all items.
