circuit card system. Thus, the artisan would have appreciated
the obviousness of replacing the conventional credit card systems
of D’Avello and Harris with similar integrated circuit card
systems.
For all the reasons discussed above, each of the
alternative rejections of claim 1 is sustained. With respect to
the rejections of claim 4, appellants argue that D’Avello
requires a host computer to determine the validity of the credit
card used to make the call rather than relying on a processing
means internal to the remote unit as claimed [brief, page 14].
Since Fuwa suggests that the integrated circuit card determines
whether or not it is valid, we find the recitation of claim 4

of claim 4. Therefore, we also sustain each of the alternative
rejections of claim 4.
