Technical Information

How Fingerprint Data is Stored

The system stores fingerprint data securely in the database:

• Each scanner type uses a different data format

• The system uses the BIOINDEX field to store scanner-specific data

• Automatic device detection ensures the correct data format is used

• Full backward compatibility with existing Digital Persona enrollments
