Description

This disclosure relates to an information processing system, an information processing terminal, and an information processing method, and more particularly to an information processing system, an information processing terminal, and an information processing method that enable more reliable settlement processing. Traditionally, fare payment systems at train station ticket gates have utilized NFC (Near Field Communication), which enables wireless communication over short distances of approximately 10 cm. When a user touches a mobile device equipped with a contactless IC (Integrated Circuit) to the ticket gate, information processing for fare payment is initiated. Meanwhile, in recent years, development has been progressing on technologies that enable contactless fare payment by utilizing UWB (Ultra Wide Band) and BLE (Bluetooth Low Energy) (registered trademark), which enable wireless communication over a wider range, in fare payment systems. For example, Patent Document 1 discloses an information processing system that performs authentication through communication over a first communication distance and processes such as ticket gates through communication over a second communication distance shorter than the first communication distance.
