> A 10c RFID tag would be 10% of the cost of many products, which im sure is unacceptable to grocery stores which I can't imagine have great margins.

If the store decides to eat the cost of those? Sure, I can buy that logic.

However, I don't see stores being unable to just raise the price of items by 10c without much pushback, which would eliminate that issue with the profit margin entirely (since the cost of it is offloaded to the customer).

I, personally, would love to be able to pay just 10c extra per item, if it meant that I can have a checkout experience similar to that of Uniqlo.
