AI Ju-mei, Hongzhen Xu, Shumin Zhou · 2007
The state of terminal device is critical to IC card system which consists of different kinds of terminal device. The paper introduce the structure of terminal device table and present a state location of IC Card terminal device based on two stage index strategy. As a keyword, the device number is a compressed four bit BCD code. The device number is divided into two parts, the previous two-bit and last two-bit correspond two index. The device state information can be located according to the index information in a fast way.
