Virtually fraud-proof authentication for wireless mobile financial transactions. A mobile telephone, genius card or dongle may capture multiple biometrics, such as fingerprint, voiceprint, retinal recognition data, facial biometric data, ear biometric data and bio print, iris scanning data, pupil movement recognition data, and send segments of each of them to a server computer that re-constitutes them and stores them for matching during an attempted financial transaction. A purchasing individual has multiple biometrics read by separate readers integrated into a single hand-held device. An automatic process of the server computer has previously sent a command packet to the hand-held device defining percentage and portion of each biometric to select and the sequence and channel of transmission for matching along with other out of band security data.
