So it will store your passwords somewhere (encrypted with a key which remains on your computer or unencrypted), and use the fingerprint to unlock the Keystore. Sorry, a tradidtional master password does the same. Reconstruction of a Fingerprint is the worst case, but even with some keypoints it stores all keypoints needed to fake a fingerprint, which works with the device. How else could it be, as the fingerprint-scan will never be the same, which prevents the use of hashing. If it really manages to generate the same "key" from a fingerprint, the fingerprint will not be really unique, because of a to gross scan The Problem with this solution: no two fingerprint-scans are fully identic.
