Our Muni-Meter approved Parking Ticket Holder is designed to be attached to your car’s windshield and will hold your parking receipt. The parking ticket clip is mounted on the inside of your vehicle windshield using the supplied 3M adhesive tape. After you get your muni-meter receipt, just simply slide it under the clip. When a parking enforcement officer comes to check your car, they will clearly see that you have paid your meter. It is that simple!
