1. An intelligent card, comprising:
- input means including a keyboard for entering identification information;
first memory means for storing the identification information entered by said input means;
second memory means for storing predetermined identification information;
means for performing a collation of the identification information stored in said first and said second memory means and for producing a corresponding collation result signal;
means for outputting a signal representing a collation result generated from said collation performing means;
means for storing time-related intelligent card validity data;
means for comparing calendar data with the validity data;
means for displaying a comparison result obtained by said data comparing means;
power source means for supplying electric power to all of said means; and
card sheet means for containing all of said means in the form of a card body.

Abstract
In an intelligent card, a keyboard has numeric keys for entering identification information and a collation execution key. A solar cell, a display device and an IC chip for performing arithmetic operations and card identification are incorporated in a case. The IC chip includes a nonvolatile memory for storing predetermined identification information. The predetermined identification information is compared with the input identification information entered at the keyboard upon operation of the key, thereby performing card identification.

21. An intelligent card containing at least an integrated circuit chip, comprising:
-
key input means having a plurality of keys for entering identification information and a first collation key for instructing card identification; first memory means for storing the input identification information entered at said key input means; second memory means for storing predetermined identification information; comparing means for comparing contents of said first and said second memory means; detecting means for detecting whether or not said first collation key is depressed; and control means coupled to said key input means, said comparing means, and said detecting means, for writing the identification information entered from said key input means in said first memory means when said detecting means detects that said first collation key is depressed, and for causing said comparing means to compare the contents of said first and said second memory means when said detecting means detects that said first collation key is released, wherein said control means and said first and said second memory means are in the form of at least one integrated circuit chip. - View Dependent Claims (22)

23. An intelligent card containing at least an integrated circuit chip, comprising:
-
key input means having a plurality of keys for entering identification information and first and second collation keys associated with card identification; first memory means for storing the input identification information entered at said key input means; second memory means for storing predetermined identification information; comparing means for comparing contents of said first and said second memory means; detecting means for detecting whether or not each of said first and said second collation keys is depressed; and control means coupled to said key input means, said comparing means, and said detecting means, for writing the input identification information entered at said key input means in said first memory means when said detecting means detects that only said first collation key is depressed, and for causing said comparing means to compare the contents of said first and said second memory means when said detecting means detects that said first collation key is released and said second collation key is depressed, wherein said control means and said first and said second memory means are in the form of at least one integrated circuit chip.
