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。
