Tagging and Metals

When I gave talks on the application of RFID tagging to packaging in a store, I emphasized how difficult it might be to replace bar codes with RFID tags, since there is still considerable metallic packaging on the store shelf, and metals interfere with RF transmissions. An article says the myth has been busted, and passive tags can coexist with metals after all.
