At 2W of power output, the next generation of commercial RFID readers will be essentially catching up to the current-2 generation of readers deployed by intelligence services - which easily read tagged items (i.e. credit cards, clothing tag, cars tires) at 5m. In the US, its about 15ft from top of a traffic signal to your car tires wireless id, and the personal tags within.

For nuclear/chemical material tracking, the larger sensors on strategic highway intersections have higher power output, of course.

The DSP design for car tire id tracking should not be too burdensome. The layout of the road, makes sensing an issue controlled problem. People at gates (vs turnstiles) are a different issue; they mass. PCSCd needs to address these different operational deployement issues, ideally.

Peter,

Whether you used a train station gate (with your mag stripe ticket) while over here in the UK recently, I don't know. Odds were that it was a Cubic gate. Their smart card version (used in London) has a PC in each gate and a max of 2 readers per bi-directional gate. Their reader is a sophisticated DSP device.

But a football stadium is a much more interesting configuration as the subject of your proposal.

Peter
