发明名称 Meter card parking system
摘要 A vehicle parking ticket is provided comprising month, day and hour indicia on the face of the card, along with three-layered laminated sections adjacent to the indicia. Use of the cards entails the irreversible destruction of the upper two layers of laminate causing exposure of a readily indentifiable lower layer, thereby preventing counterfeiting and reuse of the ticket.
