A method and system of selectively initiation biometric security based on thresholds is described. One method includes retrieving an access security level associated with an access domain and an access permission level associated with an electronic portable transaction device, comparing the access security level and access permission level, and, if the access security level exceeds the access permission level, initiating a biometric authentication process. Another method includes determining a transaction amount of a current transaction involving an electronic portable transaction device, retrieving a threshold amount from a data storage device, comparing the transaction amount and threshold amount, and, if the transaction amount matches or exceeds the threshold amount, initiating a biometric authentication process. |
