Abstract
Abstract Disclosed is a weather resistant card reader utilizing a resilient cantilevered leaf spring which provides line contact to seal the card reader from the elements during nonuse and readily permits the insertion of a card for reading when desired. The pressure exerted by the spring on the card also serves to stabilize the card during the reading process and further provides a feel that is desirable in swiping the card through the slot.
