The new tunnel, which expands the company’s RFID solutions portfolio, meets the needs of retailers’ inbound, outbound and ecommerce operations where flexibility, rapid deployment and minimal impact on existing infrastructure are key priorities.

Clustag, a company specialising in RFID and intralogistics solutions, has introduced COS Tunnel, a new open-architecture RFID tunnel designed for integration over existing conveyors, enabling the automatic verification of boxes, bags and parcels in real-world logistics environments.
With this addition, Clustag strengthens its portfolio of RFID solutions for distribution centres, offering an alternative for projects where adapting the technology to the existing installation, minimising the required modifications and accelerating time to value are the main priorities. The company officially unveiled COS Tunnel at RAIN in Action Madrid 2026, an international event dedicated to RAIN RFID technology.
“The challenge was not to launch a simpler version of our existing solutions, but to complete our device portfolio with a different proposition: COS Tunnel is designed for projects where flexibility, rapid integration and minimal impact on infrastructure are the deciding factors,” says Manolo Reguart, CEO of Clustag.
COS Tunnel has been conceived as an over-conveyor solution, configurable in width, height and operating layout. It incorporates an innovative RFID wave emission and reading-zone control system developed by Clustag’s R&D team. This system concentrates reads within the parcel transit area, improving process reliability in real-world logistics environments, while connecting the data to the customer’s WMS, ERP, WCS or WES systems through the ZENTUP data capture platform.
The solution is particularly suited to goods receiving (inbound), shipment validation (outbound), ecommerce order preparation, as well as projects in existing facilities (brownfield) where avoiding conveyor shutdowns or major line modifications is essential. Its performance is configured according to the actual variables of each application, including conveyor speed, parcel density, spacing between boxes and working environment conditions.
A more comprehensive RAIN RFID portfolio: flexibility with COS Tunnel, maximum accuracy with MOT Station
“COS Tunnel does not replace MOT Station. Each solution addresses a different operational priority: COS excels where flexibility and rapid deployment are decisive, while MOT Station remains the benchmark when maximum accuracy, a controlled RFID environment and validation in critical scenarios are the priority,” adds Reguart.
This approach enables Clustag to support its customers both in applications with demanding technical requirements and the highest levels of reliability, and in operations seeking to introduce RFID progressively, with a lower investment barrier and more agile integration into existing infrastructure.
