A method for capturing biometric data is provided that includes capturing a user biometric characteristic positioned freely in space in a video with a mobile device while moving the user biometric characteristic in response to at least one instruction. The video includes frames that each includes a user biometric characteristic image. Moreover, the method includes obtaining frames from the video and determining obtained video frames that include an optimally positioned user biometric characteristic image. The optimally positioned user biometric characteristic image is user biometric data usable for generating accurate authentication transaction results to authenticate the user. The method also includes storing the optimally positioned user biometric characteristic image included in a determined video frame in the mobile device.
