The Transcore eGo Plus Mini External RFID Tag is a beam-powered tag that can be mounted on any flat or slightly curved glass, plastic, or metal surface. This rugged tag is water and weather resistant, and its compact size makes it the ideal solution for applications that require exterior-mounting and easy installation.

The eGo Plus Mini External Tag supports factory-locked programming of fixed data fields. Agency-programmed fixed data fields can be locked by the agency using password protected programming equipment. The eGo Plus Mini External Tag supports Super eGo (SeGo), eGo, and American Trucking Association (ATA) protocols.
