A card reader for use with a card may include a card insertion part comprising an insertion port for the card; and an infrared sensor structured to detect a human body and detect movement of a person in front of the card reader. When an inserting direction side of the card inserted into the insertion port is referred to as a rear side and an opposite side to the inserting direction side of the card is referred to as a front side, the card insertion part may include a cut-out part which is cut out toward the rear side from a front end of the card insertion part. The infrared sensor may be disposed so as to face the cut-out part.
