What are the types of fingerprints

There are 4 types of fingerprints and 10 types of false which are described below

Large varieties

(1) Arch (2) Loop (3) Oral (4) Composite

False varieties

1- Simple Arch 

When a line of markings starts from one side and goes to the other and the shape is not deformed, such markings are called simple arches and have no data.

2- Tented arch

When the markings start from one side to the other, but one or two lines in the middle are raised to the tent, such a mark is called a tinted arch. It has no data.

3- Arner Loop

When a trace of fingerprints starts from one side to the other, turn to it and look like a horse, if it is on the thumb, then it is called the Arnar Loop.

4- Radial loop

When a trace of a finger starts from one side and curves towards it, the shape of the horse becomes like a snail, it has a sloping side, called a radial loop.

5- Single to Rural

When a trace of a finger starts at one point and completes at least one round of rotating rounds, it has two duplexes, one on the right and the other on the left.

6- Double Rural 

When a traces start at two points, finish at least one round by rotating round.

It has two duplexes, one on the right and the other on the left.

7- Narrow packet loop

When a packet-shaped pocket becomes rounded in the middle of a circle, it has two duplexes. One line is on the inner and the other on the outside. Such marks are called a narrow packet loop.

8- atrial packet loop

When the markings become circles in the ring but the lines of the two circles intersect at one end, such marks are called a narrow packet loop.

9- toned loop

When a mark becomes two circles but the tilt of both lines is in the opposite direction, this mark is called a toned loop.

10- Accidental Loop

When a trace is not a simple arc or a tangent arc, a superficial loop or a radial loop, a single, a reversal loop, a double, a reversal, a convex packet loop, an atrial packet loop, or a tune loop, do not resemble them. It has two or more duplexes
