Semiconductor chip-based fingerprint recognition systems have higher maintenance costs than SecuGen's system due to their fragileness. Unlike SecuGen's optical system, semiconductor-based systems use fragile and expensive parts that are equally expensive to replace and maintain. No electrostatic problems. Semiconductor systems are inherently susceptible to damage from electrostatic energy, especially in carpeted areas. SecuGen's optical system is immune to electrostatic energy.
Static electricity can actually burn out an entire semiconductor-based system.
A. High image quality. Traditional fingerprint devices require fine hand-calibration of its optical components. As such, image quality can vary significantly from one unit to another depending on the level of calibration. Accordingly, mass production of such units is costly or nearly impossible. Furthermore, such systems cannot endure high physical impact or shock, limiting their potential for outdoor use.
