To provide an authentication system allowing stable determination as to whether a user is a registered user while saving user's trouble, an information processing device capable of data communication with a plurality of image forming apparatuses extracts an image forming apparatus connected to an IC card reader from the plurality of image forming apparatuses, based on reply signals transmitted from the plurality of image forming apparatuses, and transmits user account information of registered users to the extracted image forming apparatus. The image forming apparatus connectable to the IC card reader performs, if it is determined that the IC card reader is connected to the image forming apparatus, the authentication process based on the user account information of registered users received from the information processing device and on the information read by the IC card reader. |
