ODI Security, LLC, of Mountain View, California, has designed new standalone fingerprint modules. The modules use high-security algorithms and FingerChip fingerprint sensor technology from Atmel Corporation of San Jose, California. Modules operate on batteries and are suitable for outdoor use in temperatures ranging from –40 degrees to 85 degrees Celsius. They offer high levels of sensitivity and image quality, and can operate in difficult environments, even when fingers are dirty or greasy. All modules contain a complete user interface and LED feedback for registration and use. They also have low-battery indication and the ability to drive up to five different lock actuators.
