ABSTRACT:
A slotless card reader for reading magnetically encoded cards is disclosed having an array of magnetic sensors defining a card plane, a magnetically permeable covering over said array and defining a card touch surface exposed for manually applying a magnetic card downwardly against the touch surface, or for lifting a card from the touch surface, and positioning aids for accurately aligning a magnetic card held against the card touch surface in relation to the array of magnetic sensors. The reader may further include a number of position sensors which are simultaneously actuated upon correct positioning of a magnetic card for reading, as a condition for activating the reader device and prevent premature, erroneous readings.
