Transaction terminal having base module and portable module

摘要

A transaction terminal comprises a base module which includes a printer and a portable hand-held data input module which can be removed by a user from the base module to enable the user to move around an area such as a store to gather input data. The portable data input module can then be connected to the base module for printing of the gathered data. The portable hand-held data input module may include several types of data input devices such as a keyboard, a touch screen, a digitizer and a storage disk.
