SIVA – VOYAGER™ Windshield TP M4QT – Tamper-Proof UHF RFID Windshield Label

The SIVA VOYAGER™ Windshield TP M4QT is a non-transferable, tamper-proof UHF RFID windshield label engineered for automatic vehicle identification in high-volume transportation and access-control environments. Designed for permanent installation on vehicle windshields, this RFID label enables fast, contactless vehicle recognition without line-of-sight, supporting reliable operation at speed.

Optimized for automotive glass, the Windshield TP M4QT uses a precision-tuned antenna to deliver consistent long-range performance across global UHF RFID frequencies (860–960 MHz). Its destructive tamper-evident construction ensures that any attempt to remove the label results in visible breakage, preventing reuse on another vehicle.

Built with high-quality materials that remain dimensionally stable across temperature changes, the label is ideal for vehicle access control, electronic toll collection, logistics processes, and official vehicle registration identification.
