Abstract
A system that uses cooperative arrays of electromagnetic resonating markers in combination with a vehicle mounted resonating transceiver. Markers establish their position placement during a calibration sequence in which cryptographic keys are exchanged, ensuring the markers are placed by authorized personnel and that none can be removed/relocated without detection. Markers can then be reliably polled by passing vehicles to determine relative location in areas of sensor occlusion. The markers can also be securely used for emerging smart city financial transactions such as automated parking, garbage collection, deliveries, tolling or temporary pedestrian markets.

A passive V2X transponder comprising:
- decoupled electromagnetic energy harvesting,
- a memory with capability to be locked and unlocked, including cryptographically, response modulation filters capable of operating at V2X frequencies,
- such modulation capable of being tuned to resonate centered on a specific frequency band,
- the integration of at least one passive V2X transponder into non-powered infrastructure devices selected from the group comprising road markers, signs, cones, barriers and personal safety equipment,
- the integration of at least one passive V2X transponder into at least one battery powered device where energy conservation is desired selected from the group comprising cell phones and battery powered lights,
- wherein an impedance change caused by such integration is accommodated in the tuning of the resonating structure of the transponder, and
- wherein the resonating structure of the transponder is isolated such that no impedance change occurs when integrated into such devices.
