Abstract: The present invention provides a contactless card reader (300) that prevents information stored in a contactless card from being illegally utilized, without imposing too many loads on a holder of the contactless card. The contactless card reader includes: a flat antenna for communicating with the contactless card; an angle sensor (405) for detecting an angle of the antenna with respect to a horizontal plane; and a card reading unit (302) that executes processing of reading the information stored in the contactless card, and the card reading unit executes the reading processing only in the case where the angle detected by the angle sensor is within a predetermined range.
