Abstract

The invention provides a smart card writing method and a smart card writing device. When a card writing request used for indicating the writing of a smart card is received, idle personalized data card resources are acquired, idle personalized data code number resources are acquired, and the personalized data card resources and the personalized data code number resources are sent to a terminal loaded with the smart card so as to enable the terminal to write the smart card according to the personalized data card resources and the personalized data code number resources. The idle personalized data card resources and the idle personalized data code number resources are acquired separately when the card writing request is received, so that pre-writing of the personalized data card resources into the smart card is avoided, pre-establishment of the corresponding relation between the personalized data card resources and the personalized data code number resources is avoided, and the technical problem that the utilization rate of the personalized data card resources and the personalized data code number resources is low is solved.
