Step3: Setup PIN code

• Setup PIN code to the card, then you can enroll fingerprint
• PIN is only for card management, not for authentication
• Fingerprint failed continuously, user can’t login by typing PIN code instead of biometrics verifications.

• Admin can request minimum PIN length for security

Step4: Enroll Fingerprint

• If it’s new card w/o fingerprint enrolled, type in PIN code to enroll fingerprint
• If the card with fingerprint enrolled, verified by fingerprint or type-in PIN code to continue

Step5: Manage Sign-in Data

• Verify by fingerprint or PIN to continue
• You can delete registered sign-in data from card, or assign friendly name (sign-in ID) for the registered services
