Methods and systems, related to a biometrically secured user input device for conducting a transaction are described. The user input device may comprise a biometric authentication device. At the biometrically secured user input device, a biometric sample may be received from a user. The biometrically secured user input device may transmit the biometric sample, provided by the user, to a host computer system. The host computer system may compare the biometric sample provided by the user to another biometric sample. Handwriting data from the user may then be received by the user input device. The handwriting data may be transmitted to a computer system by the user input device. Transaction data based on the handwriting data may be transmitted from the computer system to a host computer system. The financial transaction may be conducted using the transaction data transmitted to the host computer system from the computer system.
