The other surface width is in the direction which defines the one jamb depth. The one jamb thickness is in the direction which defines the doorway width. The apparatus comprises a sensor which: produces a signal when the card is presented thereto; and has thickness T, width W and height H. T<[thickness of other jamb−thickness of stop]. W is equivalent to the width of other surface. H<doorway height.
