The invention relates to a biometric authentication method, a biometric authentication system, an IC card and a terminal. Upon updating of the biometric authentication devices there can be provided a transition period during which the old and new devices coexist, and it is possible that the burden on the device providers by total replacement of the devices and the burden on the IC card users who are required to update their biometric information is reduced, and even during the transition period the authentication process can still be performed. The biometric authentication system 10 includes an IC card 100 including a reading unit 110 sending generation information back to a terminal and a writing unit 111 writing biometric information in a storage area indicated in a write instruction, and a terminal 200 including a card generation acquisition unit 210 receiving from the IC card the generation information, a device generation acquisition unit 211 receiving from a biometric authentication device the generatio
