>Игорь, я не нашел в описании ни слова о температурной карте.
Непонятно где искали. Вот, на 3 странице:
This measurement of fingerprints can be accomplished using a variety of methods, but the most promising, and the one used for the iPAQ Pocket PCs is thermal imaging. Thermal imaging is one of the most reliable methods available. Thermal imaging reads the differences in temperature between the ridges and valleys that make up a fingerprint. This method has several benefits. Among these benefits is that thermal imaging has a strong immunity to electrostatic discharge and the fact that it functions well in extreme temperature conditions. Additionally, thermal imaging is almost impossible to deceive with artificial fingerprints.
The thermal imaging technique is coupled with an image scanning process to deliver the best possible combination that provides for a lower cost to operate, reliable functionality, and security against artificial fingerprints.
