Systems and methods for biometrically authenticating a user are disclosed. In one implementation, a biometric authentication system may include a finger scanner for capturing biometric data from a plurality of sections of a finger of a user. The finger may include a distal section, a medial section, and a proximal section. The biometric authentication system may further include one or more processors configured to cause the finger scanner to capture the biometric data from the plurality of sections of the finger of the user. The biometric data may include authentication data and liveness data. The processors may be further configured to access registered authentication data associated with the user, determine whether the captured authentication data matches the authentication biometric data, and determining, using the captured liveness data, whether the finger is a live finger. Additionally, the processors may be configured to authenticate the user after the captured authentication data is determined to match the registered authentication data and after the finger is determined to be a live finger.
