Arch-Shaped Fingerprints
While some rare body features are impossible to miss, others are so discreet you may not even know you have them. An excellent example of the latter is the exclusive arch-shaped fingerprint, the least common type of fingerprint shape.
Only 5% of the population displays fingerprints that look like, well, an arch! This fingerprint shape may be hard to spot even if you look very closely at the tip of your fingers. But if you manage to stamp your fingertips, there’s a good chance you can find out if you’re one of the five percent.
