The invention discloses a digital good transaction system and the method. It mainly carries on coding process to at least one digital good in a content downloading center into a coded digital good, and the coded digital good will be transmitted to at least one content downloading station with real memory transmission path, when the consumer selects a digital good, the user can uses a content downloading card into a content downloading station, uses a reality transmission path to store the digital good to be purchased, and uses a network transmission wire to connect the content downloading center, the center incriminates the card number in order to generate a card number decoding data, and download the decoding data into a content downloading card, when the consumer want toe buy a digital good, the content can be downloaded into a content card reader, and the reader incriminate the card number to reduces the decoded data and the digital good, in order to generate the digital good which can be read and used.

本发明公开了一种数字商品交易系统及其交易方法，其主要是将至少一数字商品在一内容下载中心进行加密处理以成为一加密数字商品，而加密数字商品将以实际的储存器传递线路以直接送到至少一内容下载点中，当消费者选定一欲购买数字商品时，可持一内容下载卡至其中一内容下载点，利用一实体传输线路直接储存所欲购买的加密数字商品，并藉由一网络传输线路以连接内容下载中心，内容下载中心将根据卡号识别码以产生一卡号解密资料，并将卡号解密资料下载至内容下载卡，当消费者欲使用欲购买数字商品时，即可将内容下载卡置入一内容卡片阅读机中，而内容卡片阅读机将根据卡号识别码以还原卡号解密资料及加密数字商品，以产生可供读取使用的数字商品。

A universal card with multi-purpose refers to a card that can be used in both of card brushing reader and optical driving to fetch data. It is mainly made as to set a CD fetching face and a magnetic strip on the disc (thickenss of 0.8 mm) being produced in accordance with ISO 7816 agreement rules to fetch the data stored in the magnetic strip or IC card by inserting them to a card brushing machine or a card inserting machine. The disc also can be placed on the fetching sheath disc of 0.4 mm thickness and further to place them together into an optical driving firmly for reading out data on CD fetching face by optical fetching head in optical driving so that it is not only integrating magnetic card, IC card and CD disc for easy to carry but also increasing the safety in using, storing volume of the disc and expanding the using range.

本发明涉及一种多用途万用卡，尤指一种可同时适用在刷卡卡片阅读机及光驱内进行数据读取的多用途万用卡，其主要是在一符合ISO 7816协议规范(厚度0.8mm)的盘片上设有一CD读取面及一磁条，可插入一刷卡机或一插卡机内读取磁条或IC芯片内的储存数据，而该盘片又可放置在一厚度为0.4mm的读取套盘上，致使当该盘片放置在读取套盘后可安稳放置在一光驱内，且方便光驱内的光学读取头读取CD读取面内的数据，因此不仅可整合一磁卡、IC卡、CD片等于一盘片中以方便携带，又可提高盘片使用的安全机制、内存容量及扩展其使用范围。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
