Abstract
A fingerprint recognition method includes: from a time when a finger is detected touching a fingerprint recognition portion, a contact area between the finger and the fingerprint recognition portion is acquired at preset time intervals; when the contact area is smaller than a preset area and a number of repeated acquisition times does not reach a preset number of times, the number of repeated acquisition times is updated. The number of repeated acquisition times is configured to determine that fingerprint recognition fails when being accumulated to reach the preset number of times. Prior to the number of repeated acquisition times reaching the preset number of times, when it is detected that the finger leaves the fingerprint recognition portion, the number of repeated acquisition times is reset.
