Understanding Fingerprint Types

Fingerprint Classification Fingerprints are basically of 4 types : 1. Loop – 45 -48% 2. Arch – 7 -8% 3. Whorl – 45% 4. Accidental – 1%

Sub-Type of Loop 1. Ulnar Loop 2. Radial Loop 3. Ulnar Falling Loop 4. Radial Falling Loop Sub-Type of Arch 1. Simple Arch 2. Tented Arch 3. Tented Arch with Ulnar Loop 4. Tented Arch with Radial Loop

Sub-Type of Whorl 1. Target Centric Whorl 2. Spiral Whorl 3. Elongated Whorl – Target Centric 4. Elongated Whorl - Spiral 5. Double Loop Whorl 6. Composite Whorl 7. Imploding Whorl 8. Ulnar Peacock’s Eye 9. Radial Peacock’s Eye 10. Ulnar Spiral Peacock’s Eye 11. Radial Spiral Peacock’s Eye

Sub-Type of Accidental 1. Accidental 2. Accidental Whrol
