The present invention discloses a network-based IC card issuing system and method. The network-based IC card issuing system comprises a card issuing client, a card issuing server and an IC card reader, the IC card reader comprises a power supply management module used for supplying power to the IC card reader, a main processor and an IC card control chip connected with the main processor, and the card issuing client is connected with the card issuing server via an Ethernet. The card issuing server comprises a core board and a power supply module, and the IC card reader also comprises a network interface unit used for accessing the Ethernet. The main processor is connected with the network interface unit, the power supply management module is connected with the main processor, the IC card control chip and the network interface unit separately, and the core board is connected with the IC card reader via the network interface unit. The system and the method of the present invention realize the convenient networking by utilizing the advantages of a network, have the characteristics of long transmission distance, strong anti-interference capability and fast transmission speed, and enable the IC card issuing speed to be improved substantially.
