PROBLEM TO BE SOLVED: To improve communication response and reduce power consumption in a communication with a plurality of types of non-contact communication media.SOLUTION: A terminal device 10 accesses for reading or writing information to a plurality of types of IC cards 20. The terminal device 10 includes a CPU 11 in which, according to polling to the respective types of IC cards 20, access frequency to the respective types of IC cards 20 connected by communication is counted, a transmission time of a communication request command in polling is set longer for a type of higher access frequency, and a plurality of types of request commands are sequentially transmitted for each type according to the set transmission time for each type, through an RFID antenna 16B. |
