AWID’s RV-UHF-0-0 hands-free rear-view mirror tag has special features – invisibility and secure application, with good performance in a variety of locations on vehicles. It is easily attached by strong adhesive to the shell of the inside mirror, hidden by the windshield’s tinting. Designed for one-time use, the tag indicates any attempt to remove it. This tag, behind the unblocked windshield area where toll highway tags read, is best with readers above the travel lane.
