本発明は、合成樹脂製のカード基材の内部ある
いは表面に、不揮発性メモリチツプを実装してな
るICカードに関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an IC card in which a nonvolatile memory chip is mounted inside or on the surface of a card base material made of synthetic resin.
［発明の技術的背景とその問題点］

イプ状に磁気コートを施し、この磁気ストライプ
に口座番号や暗唱番号等の各種データを磁気記録
した、いわゆる磁気カードが広く用いられてい
る。[Technical background of the invention and its problems] Conventionally, magnetic stripes have been applied to the surface of a card base material made of synthetic resin such as vinyl chloride resin as data cards for proof of money withdrawals and withdrawals at financial institutions. So-called magnetic cards, which are coated with magnetic stripes and have various data such as account numbers and password numbers magnetically recorded, are widely used.
この磁気カードは構造が単純で耐久性が高く、
しかも大量生産に向いていることからサービス産
業分野等において広く用いられている。 This magnetic card has a simple structure and high durability.
Moreover, since it is suitable for mass production, it is widely used in the service industry.
しかしながらこのような磁気カードは、情報の

等、ごく少数の情報しか記録することができず、
したがつて例えば預金の預け入れ、引出しの記録
等の多種類の情報の記録は金融機関における預金
通帳の如く別に記録台帳を設ける必要があり、情
報処理の高能率化に対する障害となつていた。 However, such magnetic cards have a small information storage capacity, so they can only record a small amount of information such as account numbers and PIN numbers.
Therefore, to record various types of information such as records of deposits and withdrawals, it is necessary to set up a separate ledger like a bankbook in a financial institution, which has been an obstacle to increasing the efficiency of information processing.
さらに、この磁気カードは、外部から情報を比
較的簡単に読取れるため、気密保持や盗用防止等
の点で問題があつた。 Furthermore, since information on this magnetic card can be read relatively easily from the outside, there have been problems in maintaining airtightness and preventing theft.
このような事情から近年、カード内部に記憶素
子およびその制御素子を内蔵させて情報の記憶容
量を飛躍的に向上させた、ICカードと呼ばれる
データカードが開発されつつある。 Under these circumstances, in recent years, data cards called IC cards have been developed, which have a storage element and its control element built into the card to dramatically improve its information storage capacity.
ICカードは、電気絶縁性の合成樹脂製のカー

内蔵するICチツプへの情報の書込みまたは読出
しを可能としたものである。 IC cards store and process information inside a card board made of electrically insulating synthetic resin.
This card is equipped with an IC chip and has input/output terminals exposed from the surface of the card.By setting it in the card processing section of a card reader/writer installed in a financial institution, etc., it can be used to connect the input/output terminals inside the card processing section.
Electrically connect the input and output terminals of the IC card,
This allows information to be written to or read from the built-in IC chip.
ところで、ICカードは先に述べた磁気カード
と同様に常時携帯されるものであり、情報の保存
に特別の電源を必要としないことが望ましいの
で、記憶用ICとしては不揮発性メモリが使用さ
れる。 By the way, like the magnetic cards mentioned above, IC cards are always carried with them, and it is desirable that they do not require a special power source to store information, so non-volatile memory is used as the storage IC. .
不揮発性メモリとしては、マスクROMを始め

カードは携帯されるので薄型のものが望まれてい
る。 Various types of ROM, including mask ROM, are suitable as non-volatile memory, but as IC cards become more widespread, there is a need to reduce the cost per IC card, and ICs no longer require the stored information content. It is inevitable that cards will have their information rewritten and reused. Also, IC
Since the card is carried around, a thin one is desired.
