SA-4ii OEM Fingerprint Module
The SA-4ii, Cogent’s latest fingerprint OEM module, features a state-of-the-art DSP processor providing increased performance and power efficiency. Designed specifically for OEM devices requiring highly secure biometric authentication and identification, such as time and attendance or access control, the SA-4ii OEM module is 100% backwards compatible with the previous generation of the SA-4 OEM modules.

Supplied with a 500 ppi fingerprint sensor, the SA-4ii OEM module has built-in commands to facilitate the integration of biometric components into new or existing products. The SA-4ii OEM module also features an RS232 port and a TTL port to facilitate communication with a wide array of input devices, such as a PC host or a magnetic stripe, contact, or contactless smart card reader.

The SA-4ii OEM module uses a unified template that is compatible with 1:1 authentication and 1:N identification algorithms, eliminating the need to re-enroll users when switching between authentication and identification modes.

Cogent’s matching algorithm, which ranked first in Native Performance in the NIST MINEX (Minutiae Interoperability Exchange) II Test of April 30, 2009, supports multiple template formats, including ANSI-378, ISO-19794-4, PIV, and Cogent templates providing greater flexibility.
