ABSTRACT:
For use in combination with a data processing apparatus (50) which is provided with a card connecting portion for connecting a card-shaped device therewith, a portable telephone apparatus (20) has a card-shaped portion which can be connected to the card connecting portion instead of the card-shaped device. The data processing apparatus is for processing a datum. When the card-shaped portion is connected to the card connecting portion, the datum can be transferred between the data processing apparatus and the card-shaped portion. Therefore, the portable telephone apparatus enables the data processing apparatus to carry out communication relating to the datum.
