IDentity Title 21

The IDentity Title 21 Series is Sirit’s flagship product line for high speed highway applications. It complies fully with the Title 21 standard for electronic toll collection developed by Caltrans (California Department of Transportation).

Sirit has the largest install base of Title 21 compliant AVI systems in the world with installations in California (Orange County toll roads, San Francisco bridges, State Route 91, and I-15), Denver (E-470 toll road), South America and China. At the heart of Sirit’s AVI solution is the transponder or “tag”, a device that is placed on a motorist’s windshield to identify the vehicle. The tag communicates through Sirit’s antenna to a reader controller card which identifies the tag and transfers the information to the host management system. The IDentity T21 transponder can be read by the reader with an accuracy level in excess of 99.6% at vehicle speeds exceeding 100 miles per hour.From barrier-based to open highway application, IDentity T21 provides the highest performance, accuracy and reliability available.
