Description

From the listing uploaded by “appupdater”.

■Main Features 1. Easy Login - You can log in to Japan Post Bank Direct by performing biometric authentication or passcode authentication (6-digit number) using the "Japan Post Bank Authentication App". 2. Convenient Money Transfer - By performing biometric authentication or passcode authentication (6-digit number) using the "Japan Post Bank Authentication App", you can send money via Japan Post Bank Direct without using one-time password authentication with a token, etc. 3. Secure Security - Since identity verification is performed using authentication information registered on your smartphone, it prevents damage from password theft and unauthorized access by third parties. * Individual customers using a general account can use the same functions with the Japan Post Bank Passbook App. ■Notes - To use the biometric information on your device, you need to register your biometric information on your smartphone device in advance. - When customers with transfer accounts or corporate accounts send money via Japan Post Bank Direct, the app or token, etc. is required. - When using Japan Post Bank Direct, once you register your authentication information, it will switch to app-based authentication. One-time password authentication with a token, etc. will no longer be possible and cannot be reversed. * To verify your identity, we will send a verification code to the phone number registered to your account. Please register in an environment where you can receive notifications. * During registration, we will perform identity verification (eKYC) by reading the IC chip on your identification document and taking a photo of your face. You can still use the app even if you do not perform document-based identity verification (eKYC), but some services will be restricted. * Accounts set to "Do not perform transaction authentication" cannot use services such as money transfers. * If you do not use the app for a certain period of time, you may be required to re-register. * Registering a transaction code is optional, but we recommend it for security reasons. * Never share your verification code, passcode, or transaction code with anyone. * Do not reuse passcodes and transaction codes that you use for other services. Also, do not register easily guessable numbers such as your date of birth or phone number. * Please check the Japan Post Bank website for required operating environments. * The app is free to use. However, data communication charges related to app downloads, updates, and usage will be borne by the customer.
