3.2 Software Installation and Fingerprint Setup
The Lexar JumpDrive F35 PRO requires dedicated software for fingerprint registration and managing secure partitions. This software is typically pre-loaded on the drive or available for download from the official Lexar support website.

- Once installed, launch the Lexar DataShield application.

- Proceed to register your fingerprints. The software will guide you through scanning your finger multiple times from different angles to ensure accurate recognition.
- You can register up to 10 unique fingerprints. This allows multiple users to access the secure partition or provides alternative fingers for your own access.
- The software also allows you to define the size of the secure (encrypted) partition and a public (unencrypted) partition, if desired.
