the implementation of biometrics in javacard

[choimillen]

I need to finish a javacard applet implementing the fingerprint authentication.

I looked through Java Card specification v2.2.2. It describes a special package-javacardx.biometry. However,I didn't see any implementation information.

Has anyone worked on this ?
Should I use other commercial development tools ?
Any recommendation everybody?

FeiTian has implemented a fingerprint authentication system. The following is the demo information.
1.Fingerprint Scanner

2.Fingerprint match successfully (check the green V mark at upper-left corner of the right fingerprint image)

3.Failed to match (check the red X mark at upper-left conner of the right fingerprint image)

The fingerprint matching system function of each part:
1. The fingerprint scanner is responsible for collecting fingerprints.
2. The software displays of the fingerprints collected and transmits fingerprint data to the card. The card confirms if the fingerprints match successfully and returns the judgment result. Then software displays the matching results.
3. The card analyses the fingerprint data and give the final matching results.
