A new handhold device with ID card identification

摘要

With the application of 2nd generation ID card in China, it is imperative to research and develop a kind of device used to identify and verify the ID card. In this paper, we propose an original solution to implement above functions. Based on GPRS (General Package Radio Services), GPS (Global Position System) and IC (Integrated Circuit) Card technology, this solution fits the demands of the application. The state machine method is adopted to implement the software design. A practical and useful encryption algorithm is used, which meets the safety of this application completely. Our developed sample machines are tested and used. The results show that this solution is feasible and practical. In addition, the independence of the function and structure make sure that it is easier to maintain and upgrade the system according to the viewpoint of software engineering.
