Personal identification number input apparatus, control method for the same, and card processing system

摘要

Card data read by a card reader and a personal identification number inputted via an input unit are transmitted to an information processing apparatus. A timer is made to start measuring a predetermined waiting time in accordance with a notification of completion of processing using the card data and the personal identification number from the information processing apparatus. A warning is given if a card loaded in the card reader is detected by a detection unit when the measurement of the waiting time by the timer is finished.
