Abstract

Disclosed is an enhancement to the concept of identity cards. Adaptive labelling is proposed which permits changing the identity code, e.g., PIN, Bar Code, or other visually readable code, without replacement or destruction of the card label.

Active Label

      Disclosed is an enhancement to the concept of identity
cards.  Adaptive labelling is proposed which permits changing the
identity code, e.g., PIN, Bar Code, or other visually readable code,
without replacement or destruction of the card label.

      The "Smart Card" is a commonly accepted and widely distributed
device.  In its present form, it consists of a memory of various
types (RAM, EPROM, PROM) with CMOS logic components embedded, usually
within a credit card. Applications of such smart cards are becoming
widespread, and hardware is manufactured by several manufacturers.
Applications mainly involve financial management with a goal to
establish a cash-free society.

      The purpose of this article is to extend the function of the
smart card into quite unrelated areas by the addition of an LCD
display matrix on the surface of the card.  This matrix need not, for
the applications foreseen, be significantly more in content than,
say, 400 x 200 pixels, although future applications may require a
greater amount. Like the smart card of today, this new card, called
an "Active Label", can be personalized in a read/write device and
will then form a display on its surface which can be read visually or
by a number of existing techniques, such as bar code reading.

      Applications for this device occur where it is important to
identify an item or collection of items so as to be able to ascertain
its content in an accurate and timely manner...
