average of 120 to 150 points [handbook of fingerprint recognition 2009]
The points are called "Minutiae". For a DA, ADA, or any prosecuting attorney to make a case off your finger prints they will need at least 10 Minutiae Points. Of course the more the merrier. The more would make the case stronger. But 10 will do it.

There is no standard number required. In fact, the decision as to whether or not there is a match is left entirely to the individual examiner. However, individual departments and agencies may have their own set of standards in place that requires a certain number of points be matched before making a positive identification. see the following link for more information: http://www.leelofland.com/wordpress/?p=3441

A fingerprint analyst, also known as a forensic fingerprint examiner, examines, compares, and analyzes fingerprint evidence collected from crime scenes, documents, or other surfaces. They utilize specialized techniques and tools to identify unique ridge patterns and minutiae points in fingerprints to match them with known prints in databases or from suspects. Their findings are crucial in criminal investigations and can serve as key evidence in court. Additionally, they may testify about their analyses and the reliability of fingerprint identification methods.
Over the years, standardization of types and characteristics have been developed. These are cataloged and used as hyper-data in the databases. By taking a new set, applying the catalog criteria to the new prints, they can be run against the existing prints on file. The computer will match the various points and kick out either the exact match, or a handful of possible matches. The examiner then has to match them up to determine if it is a valid match.
Characteristics of fingerprints used for matching prints include ridge patterns, minutiae points (ridge endings, bifurcations), and ridge spacing. These unique features create a fingerprint that is distinctive to an individual and are commonly used in forensic analysis for identification purposes.
To positively identify a person with fingerprints, forensic experts compare the unique ridge patterns and minutiae points found in the fingerprints of the individual in question to a known set of fingerprints in a database. If there is a match in the ridge patterns and minutiae points with a high degree of certainty, then the person can be positively identified.
Fingerprints are unique due to the intricate patterns of ridges and valleys formed by the skin on the fingertips, which are influenced by genetic factors and environmental conditions during fetal development. Scientists match fingerprints to individuals by analyzing specific features, such as ridge endings, bifurcations, and minutiae points, using both manual examination and automated fingerprint identification systems (AFIS). The uniqueness and permanence of these patterns make fingerprints a reliable method of identification in forensic science.
because each fingerprint is unique.add. The quality of fingerprint evidence is very dependent on the number of points of match between the site example, and the fingerprint card. There is much poor fingerprint evidence because the belief that it is infallible has encouraged shortcuts to make it so.Unfortunately the wikipedia article does not address this 'number of points' issue at all.
