Abstract
An information writing device is used to write information on a card such as magnetic card. Information to be written on a card is manually fed into the device through a keyboard. The card may be reciprocated through a driving unit to write information thereon during its forward stroke and to read out the information during its backward stroke. The information read out is collated with the input one to visually indicate resulting coincidence or non-coincidence thereof.
