Everything You Need in the Field — Ready, Tested, and Proven

At INVIS, we provide complete field solutions for ETC and AET projects, covering every device and subsystem required at plazas and roadside installations.

Whether your project is MLFF or SLFF, we deliver a full ecosystem of field equipment — either developed in-house or sourced through trusted global partners — ensuring maximum performance, compatibility, and cost efficiency.

Our solutions are built on the experience of dozens of successful deployments, enabling clients to implement tolling projects without worrying about device interoperability or integration risks.

Focus on the Field. Freedom at the Back Office.

Our responsibility starts — and excels — in the field layer.

We design and deploy all roadside hardware and embedded software required for reliable ETC/AET operation, while allowing our clients to maintain their own Back Office and central servers independently.

This flexibility enables highway operators and system integrators to focus on transaction management and payment software, while INVIS ensures the field performs flawlessly.

For projects requiring complete integration, we also collaborate with our trusted Back Office software partners, offering a full end-to-end solution when needed.

Why We Can Deliver This with Confidence

Because we build the core of every field system ourselves.

• The Zone Controller (ZC) — the brain of the field — manages all roadside devices and communicates with central servers.
• The AVC System classifies vehicles with unmatched accuracy using a fusion of LiDAR and axle sensors.
• The AEROS ANPR Cameras capture plates with precision even at high speeds and in challenging lighting.
• And the RFID Reader Integration ensures seamless transponder communication — tested and verified with major global brands.

Every component in this ecosystem has been tested together, in real projects, guaranteeing stable operation, synchronized timing, and unified control.

Supporting devices like switches, PDUs, and UPS units are sourced from top-tier industrial manufacturers, ensuring field reliability and long-term serviceability.

Field-Proven Integration. Real-World Results.

Our field architecture is designed to minimize cost, simplify maintenance, and maximize uptime.

The result is a complete and coherent system — engineered, tested, and deployed by one team — giving clients a single, reliable partner for everything that happens between the roadside and the central server.
