> The difference is in the apparentness (is that a word?) of the crime. Right now if you put a shirt under your jacket and walk out, that is a clearly abnormal activity, anybody witnessing it will know what is being done. With these futuristic checkouts, the normal function (as it's been described to me) is to push a whole cart full of stuff through without hesitation. If some/many/most of the RFID tags are 'defective'* how will anybody know? I don't believe scales are a practical solution at this level, there's too many variables on whole cart weight.

simply bending the sticker based security tags stops them working pretty
often. My better half found this out when she was a "till jockey" and
the people tagging the items were breaking them
