RFID zappers are easy to build.

The ability to track individuals based on the signature of combination of tags that they are carrying is a privacy concern. Hence the need for RFID zappers. Or Faraday-cage fashion-wear.

Although it is claimed that some tags are readable over only a short distance; it is a short distance with the typical, commercial reading equipment. It doesn't rule out, for the majority of tags, the ability to point an antenna at somebody and to read any "illuminated" tags with a very sensitive receiver.

It still needs people to take the stuff off the shelves and to handle individual items. RFID can buttist in identifying what might still be on the shelves, and where the items are located. Staff still have to fumble through products, perhaps breaking good stuff to get to the outdated.

If you are using RFID with use-by information encoded, then the checkout is a less costly way of dealing with the problem. People are probably not fully comfortable with pushing a trolley full of groceries through a scanning gate and then having an itemised bill appear on their credit-card statement. The potential for data terrorism is almost limitless in that scenario, let alone them being billed for their underwear every time they go shopping. -- "Bernd Felsche - Innovative Reckoning, Perth, Western Australia ASCII ribbon campaign "Laws do not persuade just because X against HTML mail they threaten." and postings Lucius Annaeus Seneca, c. 4BC - 65AD.
