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.
