Controversial '''RFID''' technology identifies products according to a [[radio frequency]] signature. It is so small and cheap it may even be embedded into [[currency]]. | Controversial '''RFID''' technology identifies products according to a [[radio frequency]] signature.

RFID tags are very small chips containing a tiny antennae, and can be fixed to physical items. A number of major retailers are interested in using them as a high-tech replacement for [[barcode]]s, as they offer the possibility of improved [[stock control]] -- allowing a company to automatically count how many items it has in [[inventory]], and even knowing exactly who is buying what. | RFID tags are very small chips containing a tiny antennae, and can be fixed to physical items.

"This in turn opens up the possibility of mass surveillance, with people being tagged, monitored and profiled without their knowledge and consent through hidden RFID chips." This goes well beyond the [[user data]] we would need to deliver a detailed [[Consumerium buying signal]] to [[individual buying criteria]]. It is not clear whether such a potentially intrusive technology is inherently [[dangerous technology]] or whether it could play a role in a more [[healthy signal infrastructure]]. [[Consumerium Governance Organization]] is going to have to make difficult decisions regarding this and related questions. | "This in turn opens up the possibility of mass surveillance, with people being tagged, monitored and profiled without their knowledge and consent through hidden RFID chips."

===RFID security=== | |||
There have been reports of tests of RFID chips that function only at a very close range (20-30cm) thus reducing the risks of remote survaillance. | |||
There is also research into selectively blocking reading RFID information in the following manner: Chips can be configured to have practically any identity in the address space, thus making the tag seemingly look like any one of the possible tags. | |||
