The disclosure describes a biometric authentication system that can authorize a transaction at a retail store using a person's biometric data and password. The biometric authentication system may include a point-of-sale device that can receive a biometric data (e.g., voice data, fingerprint data, or facial data) of a person that initiates a transaction. The biometric authentication system may also include one or more authentication systems that analyzes the received biometric data, and an authorization system that compares data obtained from the one or more authentication systems and the POS device to determine whether the information obtained from the person is related to that person's biometric and password information previously stored by the authorization system.
