Sun Joins RFID Program

per unit analyzer writes: "C|Net is running an interesting article on Sun's recent affiliation with MIT's Auto-ID initiative. The article is a layman's intoduction to passive RF tag technology. The concept is to replace the ubiquitous UPC bar code with a 5-cent RF-tag. When hit with the right excitation signal, the tag emits its own RF signal encoded with a 96-bit number. The privacy concerns are obvious; items people buy could be tracked anywhere they happen to go. How would you like the security scanners at airports or even the local high school be able to generate a complete inventory of the consumer products carried by each person coming through the door? (OK Johnny, hand over that pr0n magazine in your backpack...) The Auto-ID ilk includes many of the major consumer product manufacturers and retailers. Incidently, the American Radio Relay League is also currently fighting an uphill battle to keep the RF-tag technology of Audo-ID Technology Board member Savi Technology out of the 70cm Amateur Radio band in the US." We have a couple of earlier stories about RFID tags.
