Abstract: A wireless/wired integrated biometric authentication terminal having a multiple safety lock function is provided. A customer payment system is formed in an electronic cover of the integrated biometric authentication terminal. The electronic cover has at least one of a fingerprint and finger vein authentication processing unit formed on one side, as a groove on which a finger can be put, to interoperate with the customer payment system of the POS terminal and a card information authentication processing unit formed on the other side and configured to interoperate with the customer payment system of the POS terminal to perform authentication processing on payment with a customer's card information. A customer LCD display unit for displaying a payment amount is formed on an upper front end of the electronic cover.

Abstract: Provided is an input and output integrated module for simultaneously linking biometric information algorithms, which includes an integrated module for simultaneously authenticating fingerprints and finger veins which includes a fingerprint module, a finger vein module, and a conversion module, wherein: the fingerprint module scans a fingerprint in an image sensor, compares the scanned image with a previously-stored image, and outputs a registered authentication code of a corresponding person as a specific serial communication signal when there is a person having a fingerprint identical to the previously-stored image; the finger vein module scans a finger vein in a camera image sensor after light of an infrared light-emitting diode passes through a finger, compares the scanned image with a previously-stored image, and outputs a registered authentication code of a corresponding person as a specific serial communication signal when there is a person having a finger vein identical to the previously-stored image.
