Abstract
A smart card that is responsive to a list of items with individual prices that are received from a point of sale (POS) terminal during an individual transaction to automatically insert these items into expense categories. A personal computer later retrieves these categories and associated information and inserts the information into a spreadsheet. The microprocessor in the smart card relies on stored tables defining commonly used item designations and a table that defines definitions based on an ongoing learning process by the microprocessor in conjunction with the personal computer.
