| Abstract: | For B smart card can not be manipulated by the reader with class A interface, in this paper, a contact reader/ writer of 5 V source for B smart card of 3 V source is introduced. Hardware circuit design and firmware is discussed separately. Finally, the simple application software is introduced. From the running of the system, it shows that the reader/writer has a simple structure and stable performance, providing furtherance for development reader/writer for 3 V/5 V smart card. |
