Design and implementation of the general read-write system of the smart card

The state of the art of unified read-write of the smart card of different data formats is presented. Based on the framework designing and system organizational structures of “card type determining-> function calling ->Data Conversion ->unified read-write”, a data reading, writing and reception data management of the smart card of different data formats through PC is implemented. The experimental results on smart cards of water meter, such as the RF card, TM card and IC card show that the general read-write system is feasible, and the read-write efficiency is not affected, possessing good operating conditions and scalability.
