Claim:
A transponder system, said transponder system comprising, in combination: a transponder device, the transponder device comprising a housing, the housing comprising opposed superior and inferior housing ends, and opposed anterior and posterior housing faces, the anterior housing face comprising a raised transponder-locating portion; and a transponder intermediary device made from a high memory material and comprising an inferior wall, an anterior wall having superior and inferior portions, a posterior wall, and two laterally opposed sidewalls, a windshield interface, a manually graspable finger-pull portion located on the anterior wall, the anterior wall spanning the entire width between the sidewalls, and a locator-receiving aperture located on the inferior portion of the anterior wall and allowing a user to push on the transponder device through the locator-receiving aperture, the inferior wall, anterior wall, and posterior wall together with the sidewalls defining between them a transponder-receiving slot for receiving the transponder, the sidewalls each including a slot-expansion notch formed therein, the slot-expansion notches in combination with the high memory material composition of the sidewalls and anterior wall allowing a user to manually displace the superior portion of the anterior wall away from the posterior wall by grasping and pulling the finger-pull portion, enabling the user to manually unlock the transponder-locating portion from the locator-receiving aperture, thus enabling the user to remove the housing from the transponder-receiving slot, the high memory material automatically returning the superior portion of the anterior wall to its original position when it is released by the user, the windshield interface comprising windshield-attachment means for attaching the transponder intermediary devices in a toll-paying position to an inner windshield surface, the transponder-receiving slot being sized and shaped to snugly and removably receive the housing, the transponder-locating portion being removably receivable in the locator-receiving aperture for selectively locking the housing in the transponder-receiving slots.
