Disclosed is a card payment processing device with a security function. In the card payment processing device according to the present invention, a protection board surrounds a side of a main board including a side of a case, and covers a part of the upper side of the main board, and only a part of an upper surface of the main board is soldered. Therefore, the protection board of a relatively small area is required and thus production costs can be reduced. Also, the card payment processing device of the present invention can prevent a probe from being inserted by penetrating the side of the case, by a sensing circuit of a side protection board of the protection board; prevent the probe from being inserted by penetrating the main board and a cover board, by a sensing circuit of the main board and a sensing circuit of the cover board; and prevent the probe from being inserted between an upper surface of the case and the cover board and between a lower surface of the case and the main board, by an upper protection board and a lower protection board of the protection board. Therefore, the present invention has the effect of preventing the probe from being inserted into the case completely. |
