A writing instrument and associated carrier compartment that include electronic components. A communications link can be established between the writing instrument and the carrier compartment to allow dual direction communication between the carrier compartment and the writing instrument. A biometric database includes information for registered writing instrument users. A registered user can initiate data requests through the writing instrument, providing as authorization newly collected biometric data. The carrier compartment can receive the request, process the request by contacting a respective service or data provider, and transfer the request with the collected biometric data to the service provider. The service provider, as a subscriber to the biometric database, processes the request upon verification of the biometric data. A pre-established user account can reflect the requested transaction. Authorization or other data can be transferred to the carrier compartment and stored in a removable memory component such as a diskette or memory stick. The removable memory component data can be transferred to other electronic devices for authorization. Data requests may include any digital data including financial transactions, MP3 data, digital images, etc.
