About this page

This page explains procedures for implementing the "Card-alternative Electromagnetic Record (Attribute Certification Function)" that enables identity verification using My Number Card information stored on smartphones. For both face-to-face and non-face-to-face use, procedures differ by device type (iPhone, Android, other terminals). Using official apps requires no procedures, while custom development requires applications. The page provides information on ministry-certified programs and implementation cases, regularly updated with the latest versions and guidance.
