PORTABLE TERMINAL DEVICE AND METHOD OF JUDGING COMMUNICATION PERMISSION THEREOF

摘要

A portable terminal device includes a wireless communication unit (103) which receives charging information (payment permission request information), a sub-storage unit (100) which stores electronic money information increased and decreased by the charging information (payment permission request information), and a sub-control unit (102) which performs charging processing based on the charging information (payment permission request information) received by the wireless communication unit (103). The sub-control unit specifies the upper limit of a payable amount or a charging category based on an authentication rate acquired by biometric authentication, determines whether the charging is within the upper limit of a payable amount or whether the charging is in a payable charging category based on the charging information (payment permission request information) acquired by the wireless communication unit, and provides external notification that the charging is not possible when not within the upper limit of the payable amount or when not matching the payable charging category.
