Abstract: A tamper-proof secure card comprising biometric data of an individual for identifying or confirming authority of the individual. Prior to issuing the secure card a cardholder's biometric data is stored in a transparent biometric data section of the secure card. Also, a unique card number is created using a cardholder's biometric data and stored in the card. When the secure card is used the cardholder inputs biometric data. This input biometric data is then compared to the biometric data stored in the card. If the input biometric data matches the stored biometric data the identity of the cardholder is confirmed. If the cardholder's identity has been confirmed the unique card number can be accessed. Without confirmation the unique card number cannot be access. The secure card also comprises a transparent input area to separate the cardholder from an identity verification machine.
