There is some interesting information at http://www.finger-scan.com/ They make the point that finger scanning differs from finger printing in that what is stored is a set of recognition parameters much smaller than a complete fingerprint image. So there is no need for a lengthily process to acquire an initial image. Presumably this also makes finger scan data proprietary, since each vendor will use a different recognition algorithm.
Finger Scan also has a page on accuracy where they debunk other vendors' claims of 0.01% false reject/ 0.001% false accept, but tell you to e-mail them for the real numbers.
