Accordingly, in an embodiment of the invention, a computer mouse is provided and includes a digital medium for storing executable software and user data, a wireless transceiver, a credit card reader, and a biometric scanner. A user operating the mouse connected to a computing appliance may validate stored credit card information as belonging to the user by performing a biometric match of biometrics of the user taken by the biometric scanner against biometrics and profile data stored in a network-based data server, and whereupon a successful match of biometrics invokes a graphics user interface stored on the digital medium to display on a display device accessible to the computing appliance, the interface containing the credit card information belonging to the authenticated user for the one or more cards authenticated.
