The measure of the fingerprint image quality is in dots per inch (DPI). [8] Optical scanners take a visual image of the fingerprint using a digital camera. Capacitive or CMOS scanners use capacitors and thus electric current to form an image of the fingerprint. This type of scanner tends to excel in terms of precision.
Iris scanner in action to identify people. A biometric device is a security identification and authentication device. Such devices use automated methods of verifying or recognising the identity of a living person based on a physiological or behavioral characteristic.
The fourth product is the most advanced of the group, and while it is not touchless, there is no contact with the scanner, just with an "optical scanning area." A list of nine "contactless fingerprint technologies that are worth noting" is part of the report. Of the top three, the first closed in 2011.
The EER is a quick way to compare the accuracy of devices with different ROC curves. In general, the device with the lowest EER is the most accurate. Failure to enroll rate (FTE or FER): the rate at which attempts to create a template from an input is unsuccessful. This is most commonly caused by low-quality inputs.
