PROBLEM TO BE SOLVED: To provide an IC card, a portable electronic device, and an IC card processing device which efficiently perform authentication processing.SOLUTION: An IC card comprises a communication unit, a first storage unit, a reception processing unit, a determination unit, a conclusion unit, and a transmission processing unit. The communication unit transmits/receives data to/from an external device. The first storage unit stores registration files including pieces of registration data to be compared with a plurality of pieces of comparison target data. The reception processing unit receives from the communication unit, an authentication command including the plurality of pieces of comparison target data and file identifiers of registration files storing pieces of corresponding registration data. On the basis of a comparison method to be applied to comparison between each piece of comparison target data included in the authentication command and each piece of corresponding registration data, the determination unit determines whether each piece of comparison target data and each piece of corresponding registration data match with each other. The conclusion unit concludes an authentication result for the authentication command on the basis of the determination result. The transmission processing unit transmits the concluded authentication result to the external device via the communication unit. |
