Contactless Tag Switching Between Static and Dynamic Modes

Solution Overview

Problem

Current contactless communication technologies limit the utilization of multiple functions in devices acting as targets, as they can only communicate using pre-set uni-directional or bi-directional protocols, restricting the device's ability to effectively utilize its full functionality.

Innovation Solution

The proposed solution involves an information processing device and method that allows a tag device to selectively use either a first processing mode for transmitting static information or a second processing mode for transmitting dynamic information based on predetermined requests, enabling switching between uni-directional and bi-directional protocols to enhance functionality.

AI summary

There is provided an information processing device including: a processing unit configured to select a first processing mode in which static information is transmitted or a second processing mode in which dynamic information according to a process is transmitted on a basis of a predetermined request recognized in contactless communication with an external device and to perform a process corresponding to a selected processing mode. The processing unit selects the first processing mode in a case in which the recognized predetermined request is a read request for causing information to be transmitted and selects the second processing mode in a case in which the recognized predetermined request is a write request for causing information to be written in a recording medium.
