A multifunction card includes a programmable memory, a magnetic stripe,
and an electronic ink display. The programmable memory is able to store
corresponding account data and image data for a plurality of different
accounts. The card holder is able to use a portable terminal to select
one of the accounts stored in memory. The terminal is able to write
account data corresponding to the selected account to the magnetic stripe
of the card. The terminal is also able to electronically change the
electronic ink display to the image corresponding to the selected
account. Thus, a single multifunction card, with the ability to have both
its magnetic stripe data and appearance changed in accordance with a
selected account, can substitute for many different cards.
