Kapsch TrafficCom has introduced Elumian, an innovation claimed to be the world’s first light-powered tolling transponder.
The new device offers a unique solution for automatic toll payments by converting any available light source, including natural, ambient, and artificial light, into energy, which substantially extends its operational lifespan and efficiency.
Tolling transponders, which are typically used in vehicles to enable wireless toll payments on roads, bridges, and tunnels, have historically relied on battery power.
However, Elumian incorporates Powerfoyle technology, developed by Kapsch’s Swedish partner, Exeger, to provide continuous charging from light sources, thus reducing the need for frequent battery replacements and enhancing overall sustainability.
Exeger’s Powerfoyle solar cell material has been developed to capture light across a wider spectrum than conventional solar cells, enabling it to operate efficiently under various lighting conditions.

Powerfoyle is also said to be produced sustainably in Sweden, reportedly using totally renewable electricity, with no toxic emissions during its production.
Officially designated as TRP-4010-40E, Elumian builds on Kapsch TrafficCom’s earlier TRP-4010 model and retains a plug-and-play installation process.
Furthermore, Elumian is expected to lower distribution and disposal costs compared to conventional transponders, supporting sustainable tolling practices.
Alfredo Escriba, CTO at Kapsch TrafficCom, said: “Elumian represents a fundamental shift in how we approach sustainability within our industry.
“With its extended lifespan and reduced need for replacements, Elumian helps our customers make more environmentally responsible decisions without compromising on performance or quality.”
