Because fingerprint readers on today’s smartphones are relatively small, they typically scan different parts of a fingerprint to ensure that just one press of a finger or thumb will successfully activate the sensor.

Only one of these partial scans must be a match for the sensor to unlock a phone, and since many users register multiple fingerprints on a device, there are often dozens of different partial prints registered on a phone.
