What divice is used to identify a person by a finger print?

A fingerprint scanner is the device typically used to identify a person by their fingerprint. It captures the unique patterns in an individual's fingerprint and compares it to a database of stored prints to verify identity.


How does the fingerprint reader work?

A fingerprint reader captures an image of a person's fingerprint and converts the unique patterns into a digital code. When a person places their finger on the reader, it compares the captured fingerprint with stored fingerprint patterns to verify identity. If the patterns match, access is granted.


Why there are two indentations in the pivot of a plotting compass?

The two indentations in the pivot of a plotting compass allow for greater stability and precision when drawing circles. The indentations reduce friction and ensure that the compass point stays in place while drawing curves. This design feature helps to create smooth and accurate circles.


What is a finger scanner called?

A finger scanner is commonly referred to as a fingerprint scanner or fingerprint reader. This biometric device captures and analyzes the unique patterns of ridges and valleys in a person's fingerprint for identification or authentication purposes. Fingerprint scanners are widely used in security systems, mobile devices, and various access control applications.


Is a convex shape curves outwards?

Yes, a convex shape curves outward. In geometry, a shape is considered convex if, for any two points within the shape, the line segment connecting them lies entirely within the shape. This property ensures that a convex shape does not have any indentations or "inward" curves. Examples of convex shapes include circles, ellipses, and regular polygons.


How do fingerprints help solve mysteries?

Well Fingerprints help solve mysteries and crimes and such is because a fingerprint is unique because your the only one who has that pattern such as cuts,curves,and swirls.So lets say someone did a crime and they don't know who that person is they find a fingerprint take it and study on it to see who has that fingerprint.Try and test if you or your friends have the same fingerprint if so then those people who has that same fingerprint is the same person.


How are fingerprint taken from suspects?

Fingerprints are typically taken from suspects by pressing their fingers onto an ink pad or digital scanner, which captures the unique ridge patterns on their fingertips. This process creates a fingerprint image that can be analyzed and compared against a database to identify the suspect.


Repair indentations on carpeting?

Mist it with water and blow dry it. You may need to repeat for deep indentations.


What is a convex line?

A convex line is a curved line that does not have any indentations or concavities. It continuously curves outward, giving it a smooth and rounded appearance. In geometric terms, a convex line does not intersect itself and all points on the line lie on the same side.


What is the output of a finger sensor?

The output of a finger sensor, such as a fingerprint scanner, typically involves a digital representation of the fingerprint pattern. This output can include raw data, such as ridge and valley patterns, or a processed template that captures unique features for identification. The data is then used for authentication or verification purposes in security systems. Depending on the technology, the output may also include a quality score indicating the reliability of the fingerprint capture.
