Abstract

PURPOSE:To prevent an operation unable state and the destruction of the memory contents of an IC card due to the expiration of the battery lifetime of the card by recharging the battery before its lifetime expires. CONSTITUTION:When an IC card 4 is connected to an IC card read/write device 2 via an external terminal 3, the preceding charging date stored in a memory 44 is read out to a terminal equipment 1 or the device 2. Then it is checked whether the number of days passed is larger than the prescribed value or not. If so, a charging switch 45 is turned on via a control signal. Thus a chargeable secondary battery 43 is charged. As a result, the lifetime of the battery 43 is semipermanent to prevent the operation unable state of the card 4 or the destruction of contents of the memory 44 due to the expiration of the battery lifetime. Thus the card 4 is semipermanently available.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明はＩＣカードの恥動用電源に係り、ＩＣカードを
半永久的に使用可能とする方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a power source for IC cards, and more particularly to a method for making an IC card semi-permanently usable.

〔従来の技術〕[Conventional technology]

載されている。Regarding conventional IC cards, no consideration has been given to the lifespan of the batteries used, and there have been problems in that they become unusable due to battery life and that information in the ICC card memory is destroyed. Incidentally, related techniques are described in Nikkei Communication 1988, July, U.I. No. 49, 68-P, 89.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

本発明の目的は、電池寿命によるＩＣカードの繰作不能
およびメモリ内容の破壊防止を図ることである。An object of the present invention is to prevent the IC card from becoming unusable and the memory contents from being destroyed due to battery life.

〔課題を解決するための手段〕[Means to solve the problem]

るものである。In order to achieve the above purpose, when a quick charging type secondary battery is used, and when an IC card read/write device is operated, the number of days elapsed since the last charging date recorded in the IC card memory is determined, and the specified number of days is determined. If more than a few days have passed, charging the battery will extend its life semi-permanently.

れる。The IC card 4 is connected to the IC card lead/
When connected to the write device 2, the last charging date in the memory 44 is read by the terminal device 1 or the IC card read/write device 2, and it is determined whether the elapsed number of days is greater than or equal to a specified value, and if it is greater than or equal to the specified value, a control signal is sent. Charging switch 45
is turned on, and the rechargeable type secondary battery 43 is charged.

以上の結果５充電タイプ２次電池４３の寿命が半永久的
