≝


arch


ridges enter from.one side of the.finger
rise in the center forming an arc
exit the other side of the finger




loop


ridges enter from.one side of the.finger
rise in the center forming a curve
exit the other side of the finger




whorl


ridges form.around
a central point on the finger
in a circular manner




Minutiae features



ridge ending




bifurication
a ridge splits into 2 ridges




short ridge or dot
