ABSTRACT:
Keycard reader has entry slot aimed at an angle to the vertical and a vertical lower portion so that flexible keycard is bent as it is inserted. This provides a convenient entry, precludes the malicious insertion of coins, sticks, and other objects into reader to render it inoperative, blocks light into the reader and makes it unnecessary to make an enlarged opening in the door to receive the lock.
