Functional Requirements

Feature - authentication app user experience

USF1

As a user, I want the authentication app to notify me if my Estonian ID card is not near the smartphone NFC chip when trying to authenticate, so that I know when I am holding it in the wrong place.

• App waiting for ID-card 2

USF2

As a user, I want the authentication app to require me to enter a valid PIN code to authenticate or give a signature, so that people who don’t know the PIN codes can’t steal my identity.

• Asking for PIN 1 when PIN is inserted
• Asking for PIN 2
• Asking for PIN 2 when PIN is inserted
• When user inserts an invalid PIN
