1. Effectively detect fingerprints with scar, cut, swelling, and fingers that are too dry or wet.
2. Firmware automatically ignores residual fingerprints.
3. Scratch resistant sensor withstanding ESD 20KV.
4. Effective fingerprint recognition technology by a combination of 1:1 and 1:N Matching mechanism. Low power    consumption.
5. No installation of driver is required (except Windows 98).
6. "Real-time” encryption of the entire hard disk (including boot sector and operating system) at 1.6Gbit/sec using TDES algorithms. Encryption key lengths vary from 40-bit to 192-bit.
7. Compatible with SATA
