    • The present invention provides a payment system using a digital card. The digital card consists of a predetermined image file and a data file storing encrypted card information. The digital card is issued by a card issuing server and downloaded to a user's mobile terminal and loaded on the user's terminal. In response to the user's request, the mobile terminal for loading the digital card outputs an optical signal corresponding to information in the data file. A digital card read device senses the optical signal output from the mobile terminal, converts the sensed optical signal into an electrical signal, and transmits the electrical signal to an external payment terminal or an associated external server. According to the present invention, a plurality of digital cards can be loaded on the mobile terminal without modification of hardware of the mobile terminal and the user can conveniently use the digital cards.
    • 本发明提供一种使用数字卡的支付系统。 数字卡由预定的图像文件和存储加密卡信息的数据文件组成。 数字卡由发卡服务器发行并下载到用户的移动终端并加载在用户的终端上。 响应于用户的请求,用于加载数字卡的移动终端输出对应于数据文件中的信息的光信号。 数字卡读取装置感测从移动终端输出的光信号,将感测的光信号转换成电信号,并将电信号发送到外部支付终端或相关的外部服务器。 根据本发明,可以在移动终端上加载多个数字卡,而无需修改移动终端的硬件,并且用户可以方便地使用数字卡。
