The eGo Plus License Plate Tag is a 915 MHz RF programmable, beam-powered, license plate mounted tag, which is packaged in a water-resistant case. The characteristics of this tag make it ideal for applications that require exterior-mounted, low-cost, easily installed tags. This tag supports Super eGo (SeGo), eGo, and ATA protocols. The tag is suit-able for a wide variety of automatic vehicle identification (AVI) transpor-tation applications, including electronic toll collection, airports and ground transportation management systems, parking access, and security access applications. Using an RFID tag-on-a-chip ASIC, the eGo Plus License Plate Tag offers a read range of up to 31.5 feet (9.6 meters) and 2048-bit read/write memory. The tag provides the capability to read, write, rewrite, or permanently lock individual bytes. Each eGo Plus License Plate Tag comes equipped with a factory-programmed unique tag identification number that prevents the tag from being duplicated. The eGo Plus License Plate Tag is read by TransCores family of readers, which are configurable to support a protocol compliant with ANSI INCITS 256-2001, ISO 18000-6B, and ISO 10374 standards, and the ATA Standard for Automatic Equipment Identification. This multiprotocol feature of the eGo Plus License Plate Tag makes it ideal for migrating from a mixed-tag population to a common tag. Optional features include custom external laser etching and custom programming. An optional Exterior Tag Accessory Kit makes the installed tag tamper-resistant.
