A modular signature and data capture device employs a standardized ISA bus, standardized communication ports, and standardized x86 CPU architecture to promote flexibility in using past, present, and future software and accessories. A VGA-caliber backlit LCD is superimposingly combined with a pressure touch pad that is useable with a passive stylus. The LCD displays pen drawn signatures and graphics in real-time, and can display images and data stored in the device, or downloaded from a host system, including advertisements. The LCD can also display menus, device instructions, virtual pressure-sensitive data keys, and control keys. The device includes a built-in a three-stripe magnetic card reader unit. The device accepts PCMCIA-compatible accessories including solid state memory units and smartcards, and is compatible with plug-in accessories including an external PIN keypad entry unit, a fingerprint unit, an omnibus unit including a printer and check processor in addition to a fingerprint unit. Security is provided by DES-encrypting PIN data and/or using Master/Session and/or DUKPT key management, or by using fingerprint token data as a PIN. The invention may be used to conduct paperless transactions in which the merchant is paid in realtime. Further, merchant purchase profiles may be generated on a per-user basis to promote more effective advertising.
