Abstract: A small lightweight hand-held data processing terminal is provided with several visible field display registers, one entry register, and a keyboard. When used by a route salesman, for example, the salesman initially enters information from the keyboard into the entry register, and then upon verifying that the information is accurate the salesman shifts the information up to the individual field registers which might for example relate to product code information, the number of units which are being purchased or sold, the type of transaction whether it is cash, check, credit card, or the like, and other desired information. The transaction information is initially entered in the entry register and is then shifted up to the appropriate field register. Finally, the customer identification number is entered in the entry register, the entire transactional entry is rechecked visually, and then entered into storage.
