Abbreviated as DFR (and also called a fingerprint scanner or fingerprint reader) a direct fingerprint reader is a biometrics device that uses automated methods of recognizing a person based on unique physical characteristics of a person’s fingerprint. A fingerprint is made up of a pattern of ridges and furrows as well as characteristics that occur at minutiae points (ridge bifurcation or a ridge ending). Fingerprint scanning essentially provides an identification of a person based on the acquisition and recognition (or verification) of those unique patterns and ridges in a fingerprint.
Fingerprint devices are by far the most popular form of biometric security used, with a variety of systems on the market intended for general and mass market usage.

- capacitance scanner
A type of fingerprint scanner that requires a real fingerprint as opposed to a black and white image that would be used on an optical scanner. This type of scanner senses the fingerprint using electrical current instead of light, as optical scanners do and are said to me more secure as it is more difficult […]
- shrink wrap
The phrase used to describe a type of purchase or license agreement associated with shipped goods, such as boxed versions of computer software purchased at a store. Shrink-wrap licenses usually means that the “agreement is bound with the product by plastic wrap (shrink wrap)”, and will specify rights of use, fees, warranties and limitations of […]
- concurrent use
The phrase used to describe a type of purchase or license agreement that is based on the number of simultaneous users accessing the software. For example a 10-user concurrent use license would allow ten users to log in and use the software at one time, but the eleventh user attempting to log in would be […]
- click wrap
The phrase used to describe a type of purchase or license agreement associated with tangible, shipped goods, for example boxed versions of computer software, or software which is purchased and distributed over the Internet. Like shrink wrap licensing, the click wrap purchase agreement is “bound with the product by plastic wrap (shrink wrap)” and by […]
In biometrics it is a type of fingerprint identification and verification process where the biometrics sample is matched to the user, showing the user is who he or she claims to be. Compare with one-to-many. See “How Fingerprint Scanners Work” in the “”Did You Know…” section of
