A consortium of retailers and consumer goods companies plan to unveil the replacement for the bar code next week. The upgrade will use a controversial radio technology that critics say will significantly expand the powers of retailers to track the whereabouts of their goods and the people who buy them.

Seems a method could be devised to block this signal.
The purpose of the "Radio Tag Debut Set for This Week: Wired.com" is to introduce a new technology that allows for tracking and monitoring of objects through the use of radio tags.
The radio tag technology works by attaching a small tag or chip to an object, which emits a radio signal that can be picked up by a receiver. The receiver then uses this signal to track and locate the tagged object.
This technology has a wide range of potential applications, including supply chain management, inventory tracking, animal tracking, and asset tracking. It can also be used in healthcare for patient monitoring and in transportation for tracking shipments.
Yes, the radio tag technology is considered safe. The tags emit a low frequency radio signal and do not pose any health risks to humans or animals. However, as with any technology, it is important to follow proper handling and disposal protocols.
It is unlikely that this technology will completely replace other tracking methods. It may be used in conjunction with other methods to provide more accurate and efficient tracking. Each method has its own advantages and may be more suitable for certain applications.
