Friend of mine in the mid 1980's did some PCB layout work for some guys that wanted to put RF ID's on products to replace barcodes. The idea was you just roll your shopping cart past a reader station. He said they got it sort of working. Worked but the cost was too high. And the reader RF power was way too high.
