Abstract
Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、プリペイドカードに関する。[Detailed description of the invention] [Industrial application field] The present invention relates to prepaid cards.
従来、プリペイドカードは、磁気によるもののみで認識
を行なっていた。Conventionally, prepaid cards have only been recognized magnetically.
上述した従来のプリペイドカードは、磁気によるものだ
けでカードの確認を行なっているので、カードのセキュ
リティがなく、偽造されやすいという欠点がある。The above-mentioned conventional prepaid cards have the drawback that the card is not secure and is easily forged because the card is verified only by magnetic means.
本発明によれば、カードの識別部分に、温度により性質
が変化する部材を使用したことを特徴とするプリペイド
カードが得られる。According to the present invention, a prepaid card is obtained in which a member whose properties change depending on temperature is used in the identification portion of the card.
次に、本発明の一実施例を示した図面を参照して、本発
明をより詳細に説明する。Next, the present invention will be described in more detail with reference to the drawings showing one embodiment of the present invention.
第1図を参照すると、本発明の一実施例によるブリへイ
ドカード1は、温度により性質が変化する部材(例えば
、液晶やインク等)2を一部分に塗布したもので、常温
状態のときは、その部分に変化はない。Referring to FIG. 1, a bridge card 1 according to an embodiment of the present invention is partially coated with a material 2 whose properties change depending on temperature (for example, liquid crystal, ink, etc.). There is no change in that part.
高温状態になると、第2図に示すように、温度により性
質が変化する部材2の部分が透過し、カードの識別につ
かうバーコード3が浮び出てくる。When the temperature reaches a high temperature, as shown in FIG. 2, the part of the member 2 whose properties change depending on the temperature becomes transparent, and the barcode 3 used for card identification comes out.
また、第2図の状態から温度をさらに上げることで、第
3図に示すように、カードの識別につかう暗号4が浮び
出て温度の変化で何回もの識別チエツクを行なうことが
できる。Furthermore, by further increasing the temperature from the state shown in FIG. 2, the code 4 used to identify the card comes out as shown in FIG. 3, making it possible to perform identification checks many times due to temperature changes.
以上説明したように、本発明によれば、プリペイドカー
ドに温度により性質が変化する部材を塗布しその部分が
常温状態の場合、識別不可能で変化せず、高温状態にす
ると、識別可能となり、識別を困難にすることでカード
自身のセキュリティがあり、また偽造防止にもなる。As explained above, according to the present invention, when a prepaid card is coated with a member whose properties change depending on temperature and the part is at room temperature, it is unidentifiable and does not change, but when it is brought to a high temperature state, it becomes distinguishable. Making identification difficult provides security for the card itself and also prevents counterfeiting.
